For disclosure, the secrets will need various machines and equipment. Amateur treatment of stone raw materials includes the following operations: Stone cutting (or galton); rough grinding, or riding; Thin grinding; drilling holes; Polishing.
Consider the first stone processing operation - cutting.
In the old days, when there was no diamond saw, the stone was cut with copper or brass circles, feeding abrasive powder divided by water. The speed of rotation of the circles was relatively small - from 200 to 300 rpm. With an increase in the speed of rotation, the loose abrasive is easily reset from the circle. Cut, thus, was a very long procedure. In the designs of the machines, we tried to use various mechanical devices that secured the stone, provided a uniform pressure on the saw, gradually fed the abrasive powder and turned off the machine after the end of the cutting. They also cut the strips - straight steel saws using an abrasive powder in the zone.
In the invention of the diamond circle, the cutting process accelerated significantly. As considered above, the diamond grains in the cutting circle are located in firm-frame metal bundles, which hold them to complete wear. During operation, the metal bundle is gradually engaged, exposing new particles of diamond.
If, with long-term operation, the diamond circle suddenly stopped cut, it means some diamond grains almost extended, while others have not yet been exposed. To fix the situation, cut them a piece of an old grinding circle or sharpened the graininess from 100 to 300 microns. The ego will not only improve the cutting properties of the saw, but also eliminate the eccentricity of the circle. Diamond cutting circle can be used to complete wear of the diamond layer.
In amateur practice To eliminate overheating of the diamond layer of saws and cracking of stone raw materials, lubricating cooling fluids (coolant) are used, usually cold water into which it is sometimes added for better wetting and cooling. drinking soda. It should, however, remember that water with soda is better to use in closed machines, as a soda fog is formed when working on the details of the machine, clothing and furniture. Cutting the cooling fluid is needed from two sides of the saw with flexible rubber or plastic tubes. At the end of the cutting, the diamond cutting wheel and the entire machine should be carefully witch. If this is not done, the saw blade and metal parts of the machine from water and the sludge are covered by corrosion.
A basic diagram of the device device can be seen in the figure. Usually, such a machine consists of an electric motor, a diamond cutting circle, a coolant supply system, protection from its spraying, a stubble table, on which a stone is cut, and a tank for collecting the sludge.

The machine for cutting small samples is easy to make a "skillful hand" kit type K-1, manufactured by the Mogilev Plant "Electric Motor". In it, it is necessary to slightly modify the base of the base of the machine, make a table and a mandrel for attaching a diamond saw. The "skilled hand" kit includes a single-phase electric motor with a capacity of 250 W with a number of revolutions per minute - 2500, which is enough to install a diamond cutting circle with a diameter of 125 mm (in this case, the district velocity will be 14.8 m / s) for cutting hard stones height up to 30 mm.
All the details of the table of the machine (the hull, enclosing the visor, the bath and the upper plate) can be glued from the plexigla, only for the body and the table you need to take a plexiglass with a thickness of 5-6 mm - it will make the design of tight and durable. Water is better to bring through the copper tube with a diameter of 3-4 mm. The tube must be bent in a semicircle, soldering a fitting fitting from the same tube and put on it a rubber hose for filing cold water. The tube should cover a diamond saw from two sides.
The stone during the cut holds with both hands tightly adjacent to the table, which eliminates the skew or the "jump" of the stone, and the light pressure spend through the saw. Cutting the mineral on the plates of a strictly defined thickness can be on the machine with an emphasis located on the left of the cutting circle. The position of the stop determines the thickness of the plate. The stone with the right hand is pressed to the slope and promote through the saw.
It is especially convenient to keep the stone with two hands when cutting almonds agate and minerals proper form. However, you need to very carefully turn the stone to accidentally do not squeeze it and do not break the saw.
To give a stagnation of a stable position, it is seen (cut off) the edge. The resulting support pad is pressed to the unit and spend through a diamond saw.
You can still put a stone in cardboard box, pour cement or plaster and, when it hardens, cut. At the end of the sawing, the locking cement and gypsum must be carefully removed. If you have to cut a cracked stone, it is first treated with epoxy glue and allow to dry.
It is possible to lengthen the service life of the diamond cutting circle by installing radial-stop bearings on the shaft, which will get rid of the shaft from the longitudinal and transverse backlats, as well as with the help of a slice of the emery circle, which will minimize the eccentricity of the cutting circle. When the machine operation, a lot of sludge is formed (mixtures of abrasive and stone waste). To get along with water to the bearings and other rotating parts of the machine, you need to close their screen, gasket, etc.
Cut the stone is more convenient when it moves towards a circle. Options for the plane of the table cutting machine With respect to the cutting circle are shown in the figure.
Options for installing a stubborn table with respect to the diamond cutting circle: 1 - optimal; 2 - mediocre; 3 - worst
If the stone is small in size, it can not be cut, but to polish.
The machine shown in the following figure is favorably different from the previous one that the torque from the engine is transmitted to the saw elastic bond, which absorbs the blows that occur when the stone skews allows the electric motor from the high humidity zone, thereby suppressing the main security rule , and, not less important, to obtain up to three speeds of rotation using removable or stepped pulleys. As an elastic communication, you can use any wedge belt from washing machine.

How many machines have and which one, each master decides itself. One, for example, wants to make separate stones cutting machines and for grinding, the other prefers to combine in one machine and cutting and grinding. What to choose the option? First of all, proceed from the size of the work room. A serious condition is also the possibility in minutes to replace one sawder to another or releasing the machine with cutting stone on grinding, change the speed of rotation of the working body.
Machine for cutting stone. Diamond cutting circle and electric motor are located on the same swinging frame: 1 - diamond cutting wheel; 2 - belt; 3 - motor; 4 - stone; 5 - clamping device; 6 - knob
For the manufacture of a cutting machine, it is necessary that the frequency of rotation of the diamond cutting circle is equal to 1500-2500 rpm at a row speed of 15-25 m / s. Weak, fractured stones are best cut on small revolutions (1000-1500 rpm). The optimal grain of the diamond cutting circle is 250/200, 200/160, 160/125 and 125/100. Use circles with a smaller graininess in amateur practice is inappropriate due to a sharp increase in the duration of cutting.

In addition to cut, you will need grinding machine. Sometimes grinding operations are performed on the electricity. But it can only be used in initial stage Works, since to process the stone in the vertical plane is uncomfortable.
You can, of course, install grinder It is vertically and on his shaft to attach a grinding wheel, but this is also not a way out of the position. If you put the electric motor vertically, its housing and bearings will quickly heat up, a certain force will appear along the shaft, and the presence of one speed, sometimes high, does not allow to produce stone treatment with bulk abrasive and other works. That is why ultimately will have to construct the machine with a horizontally installed rimpable tool. With the design of two types of such a machine, you can find the following figure.

Today we will talk about how to make a self-made currency machine from girlfriend with your own hands at home to cut or saw any breeds natural stone. Also consider drawings of cutting machines and cutting stones that can be made independently
Homemade stone saws. "Heart" of any stone machine is the spindle - the location of the cutting disk and the caliper feeding the sample.
The support for both nodes is a cooling fluid tank, which must be sufficiently rigid to ensure the immutability of these nodes relative to each other in the process of sawing. Such a tank is best made from plaelated sheet steel 3 mm thick, welding the locations of the connections. But you can make it from boards or tolstoy (12 mm) plywood, lonely from the inside sheet metal, soldered in places of compounds. Well done, they are practically not inferior to all-metal tanks.
Spindle is fastened to the side wall of the finished tank with bolts and washers. If the tank walls are made of wood, it is necessary to use large washers so that the tree does not adequate, and the bolts are not loosened. Clamp for stone is just a solid tree bar with a cross section of 50 x 100 mm, at one end of which the usual one is coming as a hinge door hinge.
The stone is clamped using long bolts with carrying nuts. Since the longitudinal direction of the loop cannot move, the need arises more than once to rearrange the stone in the clamp. But if a across the tank fasten a piece of the pipe, along which the sleeve slides, connected to this bar, then you can cut several plates at once, without rearring the stone in the climax. Of course, you can not achieve great accuracy here, but with some skill you can get good results.
Machine parts are also a power engine of 0, 25 liters. p., Wedge-shaped belt and protective casing. The rear wall of the latter needs to be made from any metal sheet, and the side and front side close the fabric strips, which could be lifted to monitor sawing. The finished machine and the motor are installed on a shared base, putting the sheets of spongy rubber or felt sheets to reduce noise and vibration.
The machine for cutting and grinding the stone can be assembled on the basis of an electric sharpener or an electric drilling device. This device has two shaft outputs, one - equipped with a chipper (caliper), another emery circle or a special table cheeper with a diamond or other coating. The power of the device is 0.25 kW, the rotational speed of 2800 rpm.
For the processing of the stone, other electric motors in the power dipase from 0.25 to 0.5 kW and the frequency of the rotation from 1500 to 3000 rpm can be applied.
The stand under the machine can serve as a drawer with a folding lid. The machine is attached to the lid bolts. The folding cover allows for some operations to install the machine into the focus position.
A panel table is attached to the box from the cartridge. Its height is adjustable so that you can work with cutting circles of various diameters.
On the panel table there is a guide plate, made of a duralumin corner of 30 x 30 mm. Side the protective fence of the cutting circle is installed. On the table and the protective fence, a middle line was held, which helps to orient the stone during cutting.
For the soundproofing of the machine, the bottom of the Box Stand and the supports of the appaled table are risber or felt.
Under the prefix table, the machine put the pallet with water to cool the cutting circle. To reduce friction in water, you can add a soap solution. The second pallet for water is installed under the bowl.
Homemade stonecase machines can be improved unusual design. The main thing is to comply with security techniques when working with a stone.
The principle of work of the stone saw is the same as the saws on the tree, but it is necessary to remember that minerals are much harder than wood and therefore special techniques need to be studied with them. A good diamond saw cuts soft minerals at a speed of about 5 mm / min, and more solid and viscous minerals with a slight slower speed.
The tree drank the same distance in seconds. Since diamond cutting discs are significantly thinner and many times more peeling on a tree, you need to contact them very carefully to avoid jamming, bending and breakage. The accuracy of the manufacture of stone saws is presented very high demands. This is a thin technique.
If the size of the stone is greater than 50-70 mm, it is impractical in hand in hand when sawing - uncomfortable. But stone - natural material, Therefore, it rarely has a flat platform and cannot be steadily installed on the table of saws. It is necessary to apply various clamps so that they are firmly held by the stone and excluded its turning or shaking. The clip is attached to the caliper, sliding along the guides to the cutting disk. The stone is served slowly and carefully to provide only the easiest contact with the cutting disc.
So, the main nodes of the stone saw are: the spindle on which the cutting disk is attached; Drive device for rotation of the disk; Caliper with clip clip; Capacity for the content of coolant and bed.
Those who wish to make a clinker machine with their own hands you need to know that cutting discs should be installed on sufficiently thick steel shafts, so that the stiffness of the structure and the accuracy of its operation under the action of the supplied voltages are preserved.
Small discs (diameter up to 100 mm) can work well on the shafts with a diameter of 12 mm, although preference should be given to shafts with a diameter of 15 mm. For disks with a diameter of up to 400 mm, the diameter of the shafts is needed 18-25 mm. The end of the shaft can be smaller diameter if the rest has an appropriate diameter.
Disks on both sides are fixed with flanges to provide rigidity and uniformity of their rotation. Thin discs require large flanges than discs thickening. For a disk with a diameter of 112 mm, the flanges with a diameter of 75 mm should be used; for discs in 200 mm - flanges 37-50 mm; For 300-400 mm - flanges 75 87 mm. In some cases, when it is required, for example, to cut down thin slits with great accuracy, the flanges can only at 12 mm do not reach the edge of the disk.
All the details of the table of the machine (the hull, enclosing the visor, the bath and the upper plate) can be glued from the plexigla, only for the body and the table you need to take a plexiglass with a thickness of 5-6 mm - it will make the design of tight and durable. Water is better to bring through the copper tube with a diameter of 3-4 mm. The tube should be bent in a semicircle, solder the fitting of the same tube to it and put on it the rubber hose for the supply of cold water. The tube should cover a diamond saw from two sides.
The stone during the cut holds with both hands tightly adjacent to the table, which eliminates the skew or the "jump" of the stone, and the light pressure spend through the saw. Cutting the mineral on the plates of a strictly defined thickness can be on the machine with an emphasis located on the left of the cutting circle. The position of the stop determines the thickness of the plate. The stone with the right hand is pressed to the slope and promote through the saw.
It is especially convenient to keep the stone with two hands when cutting almonds agate and minerals in the wrong shape. However, you need to very carefully turn the stone to accidentally do not squeeze it and do not break the saw.
To give a stagnation of a stable position, it is seen (cut off) the edge. The resulting support pad is pressed to the unit and spend through a diamond saw.
You can still put a stone in a cardboard box, pour cement or plaster and when it hardens, cut. At the end of the sawing, the locking cement and gypsum must be carefully removed. If you have to cut a cracked stone, it is first treated with epoxy glue and allow to dry.
It is possible to lengthen the service life of the diamond cutting circle by installing radial-stop bearings on the shaft, which will get rid of the shaft from the longitudinal and transverse backlats, as well as with the help of a slice of the emery circle, which will minimize the eccentricity of the cutting circle. When the machine operation, a lot of sludge is formed (mixtures of abrasive and stone waste). To get along with water to the bearings and other rotating parts of the machine, you need to close their screen, gasket, etc.
For the manufacture of a cutting machine, it is necessary that the frequency of rotation of the diamond cutting circle is equal to 1500-2500 rpm at a row speed of 15-25 m / s. Weak, fractured stones are best cut on small revolutions (1000-1500 rpm). The optimal grain of the diamond cutting circle is 250/200, 200/160, 160/125 and 125/100. Use circles with a smaller graininess in amateur practice is inappropriate due to a sharp increase in the duration of cutting.
Now about the cutting machine device. The home machine is a lot of compromises and simplifications compared to industrial, but also strict requirements are presented to it. The most important one is to minimize the eccentricity of the cutting circle on the shaft, the eccentricity of the bearing shafts, longitudinal and especially transverse shaft backlates (good results can be obtained using radial-resistant rolling bearings). These measures will allow to significantly lengthen the life of the cutting circle and avoid nail-like bores on the surface of the stone.
The shaft bearings need to be protected from the sludge, which is formed during cutting and, together with the coolant, sprinkles and settles on the details of the machine. The sludge has high abrasive and corrosive properties. Conventional felt or rubber glands protect the bearings is not enough, you still need a minimum shielding protection.
The easiest way to make the machine whose diamond circle is satisfied directly on the axis of the electric motor. The frequency of rotation of the circle with a diameter of 200 mm should be 2500-3000 rpm. With such a scheme, it is necessary that the engine bearings are very accurate (for example, sliding bearings), and the rotor is well balanced. Otherwise, such an expensive and rare tool, like a diamond circle, will not last long.
If it is not possible to purchase good engine, You should choose the design of the machine with an elastic connection between the motor and the circle.
The best results gives a clinorem transmission. It absorbs hard blows when the stone is skewed, allows you to bring the engine from the zone of a large humidity, as well as the simple selection of the diameters of the pulley to get the frequency of its rotation necessary for the good work of the engine, regardless of the engine revolutions. The design needs to be thought out to replace the cutting discs easily, without viewing the machine. The diameter of the flange fastening the circle to the shaft may be small, only 8-10 millimeters larger than the diameter of the circle planting hole. The electric motor is best acquired by single-phase, asynchronous with a capacity of 180-230 watts. Such engines are used in household appliances and are always available.
The coolant should be supplied to a circle on both sides, and so that its entire surface is moistened. It is usually bodied by two flexible tubes, slightly pressed to the sides of the circle. They are closer to the axis and 30-40 millimeters above the line connecting the shaft axis with the center of the working section of the circle.
When cutting, the coolant is sprinkled, and it is necessary to take care that it falls into the catchment.
Developing protection should be remembered that about 60-70% of water is sprayed in the plane of the rotation of the disk. Runs on the side goes at an angle not exceeding 5-10 degrees. The figure shows the direction of fluid separation. It is most difficult to manage with the rest of 30-40% of the fluid, since it is precisely this part that will fly out quite evenly in all directions. Fortunately, the splashes formed at the site of the entry of the disk to the stone almost do not contain sludge. The sludge goes from below and sinking in the bath.
Good protection against splashing can be obtained in the following design. Here in the front of the bath is attached an apron of polyethylene or oilcloth, which top Butterflakes around the neck of the wizard. If it is made great enough, then almost all splashes, flying outside the machine, fall on the apron and flow into the bath. From the bath, the liquid with sludge on the tube (diameter of at least 10 millimeters) is removed from the machine. The amount of water supplied will have to be selected experimentally, but, as a rule, it is enough that, when the motor from the circle is broken, a thin strika (necessarily from two sides) and was not divided into drops, at least for 3-5 centimeters of its free fall.
It should not be especially alleviated by the machine, the more its weight, the larger samples on it can be cut. It is best to mount the machine stationary. For example, in any bedside table. You can cut the stone as at the stop (table), pressing the stone to it and moving on the surface, and without it, when you just keep the stone with two hands. The advantages of the last way are that it is possible to completely arbitrarily choose a plane of cutting, regardless of the shape of the stone and slowly turn it into this plane, which is 2-5 times the case is 2-5 times. The disadvantages include relatively rapid wear of the instrument (uneven cutting edge generation) and the fact that the stone is quite difficult to keep in the cutting plane.
.
To master this technique follows with caution, since when the stone is skewed, it can be knocked out of the hands, and the tool is broken. When working with a stopping, the plane of cutting is forced to choose so that the stone resistantly lightened to the table and did not roll on it. Cutting with an emphasis is easier and safer in the sense of breakdown tools, a diamond circle is preserved better, but it goes much slower. The stone is served on a circle with a slightly pressing, it increases the cutting speed, but too large pressure leads to the ingun of not yet worn diamond grains. However, the skill appears pretty quickly.
As already mentioned, the stone can be cut and without a diamond circle, as they did before his appearance. For cutting take a brass or copper disk and abrasive powder supplied to the place of cutting in the form of casis. Additional cooling is not required, since the heating in this case is insignificant. Any of the above-mentioned machines is suitable for work, in which the disc rotation frequency is reduced to 200-300 revolutions per minute. For greater speed, the abrasive will be discharged from the disk. Cutting is very long, and to accelerate it is desirable to make a device that automatically feeds the cashem and the holding stone. Here the stone is fed under the action of its own weight and the weight of the lever on which it is rigidly fixed.
The other end of the lever is freely rotated around the AA axis, strictly parallel axis of the cutting circle. Rounding, the cutting wheel passes through a layer of oil-abrasive suspension and carries cutting particles along with oil. Considering the slowness of the process, you can fix the limit switch on the path of the lever to automatically turn off the machine at the end of cutting.
In addition to the outlined methods, a stone is also cut with straps - straight canvases like havice. Strips are made of steel with a diamond cutting part. Strip machines are used for simultaneous stone cutting into several plates. The frame is lowered on the stone unit with parallel stripped strips. The crank mechanism tells her reciprocating movements. The cutting field is irrigated by a liquid that cools, lubricates and carries sludge. In this principle, you can imagine different variants Amateur machine, working not with a diamond instrument, but with an abrasive suspension.
The most common way to serve stone on cutting tool. Reverse option is possible: the stone is fixed, the cutting tool is served, installed with the engine on the swinging frame.
The main elements of the clinker machine are:
- Steel shaft on which the cutting disk is attached;
- Pulley and belt connecting the electric motor and shaft;
- The platform on which the sawdust material moves.
The principle of his work is no different from the machine for the tree, with the only accounting that the stone is much harder than wood, so some special techniques need to know. Diamond saw cuts a stone at a speed of 5 millimeters per minute, and more solid and viscous materials are slower.
Note! For the normal cutting of the stone, the shaft must be tough and not fade, and the bearings should give the accuracy of rotation.
When working, keeping the stone more than 50 millimeters in the volume is impractical and uncomfortable. But natural material is very rarely the right form, so it does not have a flat platform and stability. To fix it, special clamps are used, which protect the stone from trembling and turning. Clips are attached to the caliper, which slides towards the cutting disc. A stone is applied carefully and slowly so that there is a minimum contact between its surface and the cutting disk.
How does the system work?
Stone grinding can be made on ordinary glass using abrasive powders. It is only a few drops of water and a little powder to apply on the glass. Now you can start work. During the process, the powder is gradually added with small portions as the abrasive wear is used, and the water is added to be maintained in order to maintain a sour cream. Cutting a stone with a transition from a large fraction to smaller, hands, glass and stone should be washed with water and a brush, because if there will be some grains of a large fraction in a small fraction, then all work will be spoiled.
Important! All work should be carried out only in protective glasses.
This is one of the schemes, how the smooth clinisse machine works. Different speciesThe schemes and designs of such machines are quite a lot, and you can do from various infringement materials. They can be collected from spare parts of an old motorcycle, lawn mowers and so on. For those who want to make the machine alone, one of the designs of the machine for cutting medium-sized stones will be described below.
Collect the tool yourself
A motor from a washing machine can be used as a motor in a stonecase machine, with a capacity of 180-250 watts and with the ability to develop 1500 revolutions per minute. With such data, the pulley may be two-stage with a gear ratio of 1: 1 and 1: 0.35. The first is more convenient for stone processing with abrasive material, which is attached, the second is to quickly work with bulk powder.
As a gear, a wedge-like belt is perfectly suitable from "Zaporozhets". The carving of the attachment of the table cheeper can be both left and right, the main thing is that during operation under the load of the table cheeper did not fly from the axis. Corto for collecting the sludge should be twice as much as the table cheeper, and its height is two centimeters above. Rubber is fastened to the side walls, so that the stone does not accidentally unfastened.
All work with a stone is made with the addition of water, but a special dropper is used only to work on the tables with a fixed abrasive. If the work is carried out with a bulk abrasive, it is better to use the hotel bath for wetting. Kamnezny machine with their own hands, made by this principle - it is simple and enough effective method Get the necessary blanks.
Note! You should always have about the reserve sufficient number disks.

Stamine Machine
Kohrine saw nothing particularly different from the usual circular saw For wood and in essence is a fairly simple mechanism. In both designs, you can see almost the same devices.
The main parts of the clinker machine are:
- steel shaft or spindle on which the disk is mounted,
- pulley and wedge belt connecting the shaft with an electric motor
- as well as a platform, or a caliper where the sawn material is placed.
To the stone sawing, it is necessary to have a container with a coolant for immersion disk in it when rotating to cool the saw and flush the stone dust from it.
The principle of work of the stone saw is the same as the saws on the tree, but it is necessary to remember that minerals are much harder than wood and therefore special techniques need to be studied with them. A good diamond saw cuts soft minerals at a speed of about 5 mm / min, and more solid and viscous minerals with a slight slower speed. The tree drank the same distance in seconds. Since diamond cutting discs are significantly thinner and many times more peeling on a tree, you need to contact them very carefully to avoid jamming, bending and breakage. The accuracy of the manufacture of stone saws is presented very high demands. This is a thin technique.
If the size of the stone is greater than 50-70 mm, it is impractical in hand in hand when sawing - uncomfortable. But the stone is a natural material, so it rarely has a flat platform and cannot be steadily installed on the saw table. It is necessary to apply various clamps so that they are firmly held by the stone and excluded its turning or shaking. The clip is attached to the caliper, sliding along the guides to the cutting disk. The stone is served slowly and carefully to provide only the easiest contact with the cutting disc.
So, the main nodes of the stone saw are: the spindle on which the cutting disk is attached; Drive device for rotation of the disk; Caliper with clip clip; Capacity for the content of coolant and bed.
Those who wish to make a clinker machine with their own hands you need to know that cutting discs should be installed on sufficiently thick steel shafts, so that the stiffness of the structure and the accuracy of its operation under the action of the supplied voltages are preserved.
Small discs (diameter up to 100 mm) can work well on the shafts with a diameter of 12 mm, although preference should be given to shafts with a diameter of 15 mm. For disks with a diameter of up to 400 mm, the diameter of the shafts is needed 18-25 mm. The end of the shaft can be smaller diameter if the rest has an appropriate diameter.
Disks on both sides are fixed with flanges to provide rigidity and uniformity of their rotation. Thin discs require large flanges than discs thickening. For a disk with a diameter of 112 mm, the flanges with a diameter of 75 mm should be used; for discs in 200 mm - flanges 37-50 mm; For 300-400 mm - flanges 75 87 mm. In some cases, when it is required, for example, to cut down thin slits with great accuracy, the flanges can only at 12 mm do not reach the edge of the disk.
The saw shaft is supplied with bearings to provide easy and accurate rotation. Durable are ball bearings that need to be applied. Saw with ball bearings retains accuracy after very many hours of working with a stone, which provides a straight line and long-term efficiency of the cutting disk.
Some saws use sliding bearings, but saws with such bearings quickly lose their accuracy in operation, if significant efforts are attached to the ends of the shafts. Shafts begin to vibrate, the accuracy of sawing is lost. Therefore, in most modern saws, only ball bearings are applied.
Most bearings, of course, need lubrication, especially sliding bearings in which a thin oil of oil helps to center the shaft and prevent friction.
Today, several types of bearings have been developed, which cost without lubrication at all or require its occasionally. In some ball bearings, lubricants are laid during their manufacture, and in the future they no longer require refueling due to the presence of glands. These bearings are protected from abrasive powder, which quickly displays the bearings of other types.
Slip bearings from porous bronze do not require care. Bronze in them is impregnated with oil providing lubrication for many days.
It should be remembered that the shaft of any clinker equipment is independent of its type, should be tough and not fade, and the bearings of any design should ensure the accuracy of rotation - then the cutting of the stone will take place without difficulty.
The caliper and clamping devices of the machine are the following in the importance of details after cutting discs and spindle. They serve to hold and feed stone to the cutting disk. Modern machines are equipped with massive calipers and clamps that make it easy and accurately manipulate a stone from a small size (5-7 cm) to a large - 30 cm.
For the clips of the stone, metal sponges are usually used for considerations of strength, but their inner surface is usually lined with solid wood pieces, due to the elasticity of which the best stone capture occurs. Proppite slides or roll forward on the guides, which are adjusted in such a way as to promote the caliper for a certain distance. The most important requirement, the provision being to any clinker machine, is that the caliper slides or rolling strictly parallel to the plane of the cutting disk. If this is not, then when sawing the stones of a large size, the disk will be thrown about the stone and bend.
The feeding of the caliper in simple machines is carried out by severity of the load attached to the cable, which is transferred through the unit and is connected to the sliding caliper, moving towards the cutting disc. The master turns on the motor and hands moving the caliper so that the cutting of the stone began. When the depth of the cut reaches 12 mm or more, the cargo is allowed to pull the caliper. The weight of the cargo is adjustable depending on the size of the sawn stone.
This design has drawbacks.
Since most of the stones processed are irregularly form, cross section They are changing, that is, in places they will be wider, and in some places. Consequently, the load must be harder, then it is easier. Therefore, if the sawing is not to pay constant attention, it will be difficult to regulate the mass of the cargo. If the load is sufficiently heavy, then the cutting disk, getting into thin cross sections will experience a harmful pressure for it and will quickly come into disrepair. If you choose a lot of cargo mass, counting on thin cross sections, then it will drag the sawing of thick sections.
Another disadvantage of the structure is that at the end of the sawing, when the cross section of the stone suddenly narrows and the speed of the cutting disk due to the decrease in resistance increases sharply, the remaining piece of stone is often closed and the gearbox remains on the path of the cutting disk, which is not cut off when further promotion , but climbs on it, which causes the bending of the disk in the form of a plate. A curved disk in further work is becoming increasingly crushing, and finally, the deformation reaches such sizes that further sawing is impossible and the disk has to be thrown away, even if there are a lot of unused diamond.
But these are inexpensive such machines, since they do not have a complex feeding mechanism, and, if the lover's master is familiar with the specified shortcomings, he, exploiting a saw with appropriate precautions, can receive good results.
Of mechanical methods The caliper feed is particularly often used by a screw feed and feeding with the use of cargo adjustable mass.
When screw feeds use a long shaft with cutting, which passes through the caliper or connects to it through the chassis nut. When the cutting disk rotates the shaft slowly rotates and moves the caliper forward. Some machines provide for different speed of rotation of the shaft and, therefore, the ability to adjust the caliper feed rate. Large sections or viscous material, for example, jade or chalcedony, require minimal feed speeds.
Soft materials (calcite onyx or snake) can be cut with higher feed speeds. A valuable feature of some machines with a mechanical feed is the presence of a clutch of the clutch, which does not allow the disk jamming in the stone if the cutting speed of the stone lags behind the feed rate.
Clamping devices
Many calipers are equipped with a transverse feed, which allows you to cut several plates from the stone, before the stone moves into the clamp. Press the stone should be very carefully so that it does not break out when sawing and did not damage the disk. Many novice lovers, cutting a stone on the plates, insert into the clamps only a small part of it, hoping to get as much plates as possible until the next rearrangement of the stone. But if the stone is fixed not securely, it can move and sometimes bend the cutting disc that damage will be irreparable.
Exact clamps make it possible to cut off the plates with a thickness of up to 1.5 mm or blocks with a thickness of up to 100 mm.
Cooling fluids of stone machines
The stone machine must be equipped with a bathroom with a liquid through which the cutting disk will pass during rotation. When sawing, a lot of heat stands out. It is warm, as well as stone dust formed during cutting, should be given. But the liquid is needed as a lubricant, which reduces the friction of the stone disk.
Fluids used during stone sawing are called cooling.
However, cooling is not the only goal. It is convenient to use light, almost colorless oils, which are used in the auto repair shops, as well as kerosene, to which ordinary engine oil is added in proportion of 1-2 parts of the oil on 10 parts of kerosene.
You can use diesel fuel.
Diesel fuel and kerosene - flammable. It is best to keep them outside the house or room where the stone is treated, and not shed them to the floor. The floor under the machine must be covered with a material from which it is easy to erase the spilled fluid, and the oil rags will be thrown into a safe place.
Water-oil emulsions can be used to cut the stone, which are used when processing metal on melloweer-mounted machines. However, they can contribute to the occurrence of corrosion of the machine parts, even if they are thoroughly wipe and clean.
Therefore, manufacturers of stone processing machines require not to apply in the operation of emulsion and water.
With good results, antifreeze used in vehicles as non-freezing fluid is used as a coolant. He evaporates slowly, does not ignite and almost odor.
Catching cutting stones, you must have a bucket or a solution with a solution at hand detergent For laundering the cut plates from oil surplus.
With a large squeeze, sawing should be a box with sawdusts to absorb excess oil, it is necessary to take care of anti-shirtlessness.
Rags used to remove oil cannot be stored in closed containers, as they can be self-splash. Cooling oils easily penetrate the stone, so they need to be quickly removed to pollute the artistic and jewelry material as little as possible.
Turquoise, varislicitis and other porous minerals absorb oil very quickly, so before sawing, they need to withstand several days in water, which will fill the pores and prevent oil penetration.
At the bottom of the pallet, sludge from thin particles of stone dust, which must be periodically deleted. In order for the slurry tightly donkey on the bottom of the pallet, for several days the saw does not use. Then the liquid above the sludge is carefully drained and if desired, it is used to be damaged. The pallet is thoroughly cleaned, purified purified oil into it and a portion of fresh is added to bring the fluid level to the corresponding mark. According to the rules, the cutting disk must be immersed in a fluid to a depth of no more than 6 - 12 mm.
Many stone saws are arranged in such a way that the tank not only serves as a coolant container, but is also constructive elementcarrying spindle and caliper. Then the tank is usually made from a thick steel sheet, welding the places of compounds.
In the machines of another type, the tank is made of thin sheet steel and insert into wooden drawerwhich serves as the basis of the entire design of the machine. It is important that it is hard, as it is a support for a caliper and a spindle with a cut off disk and provides them with a strictly defined location relative to each other.
Regardless of whether the machine is homemade or manufactured by the industry, it should stand vertically and firmly on its basis.
Noise and vibration can be significantly reduced by putting felt or spongy rubber under the supports of the machine. For the machine you can make a special stand from the boards, which is better than a cross section of 60 x 120 mm.
The machine requires a protective casing that would delay the oil splash when the cutting disk rotates and returned it to the tank. The housings are made of metal, plastics.
When designing a homemade clinping machine, you need to know that the main thing is the spindle in it - the place of installation of the cutting disc and the caliper feeding to the stone disk. The support for both nodes is a cooling fluid tank, which should ensure the immutability of these nodes relative to each other during sawing. The tank is best made from a sheet steel with a thickness of 3 mm, welding the connections. But it can also be made of boards or thick plywood (12 mm), lining from the inside by sheet metal, soldered in places of compounds. If such a tank is good, it will not give way to the Baku made of metal.
The spindle is attached to the side wall of the finished tank with bolts and washers.
If the walls of the tank are made of wood, it is necessary to use large washers so that the tree is not adequate, and the bolts are not loosened. The clamp for the stone can be made from a solid wood bar with a cross section of 60 x 120 mm, at one end of which the usual door loop is coming as a hinge. The stone is clamped using long bolts with carrying nuts. Since in the longitudinal direction of the loop, it cannot move, the need arises more than once to rearrange the stone in the clamp. But if across the tank fasten a piece of pipe, along which the sleeve flashes, connected to this bar, then you can cut several plates at once, without rearring the stone in the climax.
For the manufacture of the machine, the engine is also a power of about 0.25 kW, a wedge belt and a protective casing. The rear wall of the casing is made of metal sheet, and the side and front sides are closed with strips of the fabric that can be lifted to observe the sawing stone.
The finished machine and the motor are installed on a shared base, putting the sheets of spongy rubber or felt sheets to reduce noise and vibration.
The machine for cutting and grinding the stone can be assembled on the basis of an electric sharpener or an electric drilling device. This device has two shaft outputs, one - equipped with a chipper (caliper), another emery circle or a special table cheeper with a diamond or other coating. The power of the device is 0.25 kW, the rotational speed of 2800 rpm.
For the processing of the stone, other electric motors in the power dipase from 0.25 to 0.5 kW and the frequency of the rotation from 1500 to 3000 rpm can be applied.
The stand under the machine can serve as a drawer with a folding lid. The machine is attached to the lid bolts. The folding cover allows for some operations to install the machine into the focus position.
A panel table is attached to the box from the cartridge. Its height is adjustable so that you can work with cutting circles of various diameters.
On the panel table there is a guide plate, made of a duralumin corner of 30 x 30 mm. Side the protective fence of the cutting circle is installed. On the table and the protective fence, a middle line was held, which helps to orient the stone during cutting.
For the soundproofing of the machine, the bottom of the Box Stand and the supports of the appaled table are risber or felt.
Under the prefix table, the machine put the pallet with water to cool the cutting circle. To reduce friction in water, you can add a soap solution. The second pallet for water is installed under the bowl.
Homemade stonecase machines can be improved unusual design. The main thing is to comply with security techniques when working with a stone.

Stamper machine. Some types of machines:
The clinker machine, in which free abrasive is provided, has a number of advantages regarding equipment with diamond cutting tools.
Advantages and disadvantages of saw with a free abrasive
First of all, they are significantly cheaper, since the canvas itself and the abrasive component have low cost in comparison with diamond cutting discs. At the same time, such machines can be designed quite large, which will allow to silent bulky stone blocks and plates.
At the same time, if you try to handle such blocks with diamond discs, it will entail significant additional costs. On the other hand, in situations where the defining factor is the speed of work, the stone-cutting machines with free abrasive are inferior to equipment equipped with diamond discs. This is due to a slower sawing machines with a free abrasive.
Types of clinner equipment with free abrasive
Currently, a clinical machine with a free abrasive, equipped with three types of working tools, is presented on the market. First, it is a disk cloth. Secondly, there are ribbon canvas. There is also equipment with wire canvases. Machines equipped with ribbon canvases are divided into two types. There are those equipped with frame saws with the movement of the cutting tool forward and back. The principle of operation of the machines is similar to a conventional manual saw. In addition, there is equipment with ribbon saws equipped with a narrow belt cutting tool that moves around the rollers in the vertical direction.
General principles of work
In the clinical machines of all these three types, a mixture of silicon carbide is sent to a canvas or wire in the form of a suspension. It falls into the groove and, praised by a moving cutting tool or wire, destroys the stone, gradually deepening cutting to the full separation of the stone. At the same time, it is appropriate to note that the saws of the circular type are treated with stone blocks very neat. As a result, it cuts with such machines a flat and smooth surface of the material, often more high Qualitythan after processing a diamond disk. After processing a stone with tape saws, wavy uneven planes often remain. The result of the work of such machines depends on the width of the canvas.
A wavy surface is obtained and after cutting a stone with a havice saw. At the same time, if the cutting tool is quite long, the stone surface will be smooth and smooth. The most low-quality planes of the treated material leave wire machines. This is due to the constant deviation of the wire after any minor lateral movement of the unit, which leads the cutting element in a reconnect movement.
Machine with straight web and free abrasive
Such a stone machine to make is much easier than the disk. In addition, after work, significantly less dirt remains. With this design, there are practically no restrictions on the size of the cutting tool. There are even amateurs who produce a stone machine with their own hands using in its design of 180 centimeters with a width of about 150 millimeters in its design. It should be borne in mind that a thin canvas vibrates strongly, so it is recommended to strengthen the longitudinal slats from the wood. Therefore, in the manufacture of such equipment, it will be necessary for your own efforts. detailed drawing Stone machine. In the saws of a small size, the cutting tool is fixed by the stand, similar to the goats, which were previously used throughout the seeding of firewood.
In the design of small saws, a cloth with a thickness of 0.8-1 mm is used. Such a cutting tool is made of soft steel, and for larger devices, a thickest metal sheet is required for larger devices. It is necessary to ensure the continuous flow of water and the abrasive powder in the area of \u200b\u200bthe cutting of the stone. Abrasive composition, gradually cutting material, picked up by metal sawing tool. A drops of water falling down on the powder, create conditions for the constant and evenly distributed flow of the mixture into the cutting zone through a special manufacturer of plasticine bath. When carrying out work using free abrasive, the mixtures of number 100 and 220 are used. Many are made by their own arms of stonecases. Instructions of specialists and experienced designers will be quite by the way.
Wire Machine
The largest distribution such a stone machine received in China. With their help, massive boulder boulders are cut into small and comfortable pieces of material for further work. When using such equipment, there are practically no restrictions on the size of the stone that can be cut by this machine.
The only thing that limits these dimensions is the arc parameters to which the cutting wire is installed. This element of the equipment must have a sufficiently large dimensions, which allows the whole to cover the stone. 
There are two types of wire machine. In the first version there is an arc, in the second - rollers. In the arc method, the cutting element is stretched between the ends of the arc made of wood, and in the roller type it is rewinding from one cassette to another. At the same time, the direction of rotation of the Bobin changes after the completion of one complete rewind.

Homemade machines do it yourself: components
If a person often faces the fact that he needs to make anything from a tree, just likes to do it or makes things to order, then he simply needs a machine. Acquire such things not only expensive, but they are not always suitable in size, may be inconvenient or not fit into the design. But the homemade machine with their own hands, made on the desired size, perfectly fit into the room space and will always be comfortable.
Engine
If it was decided to make this device on your own, then it is important to choose the right components correctly. For example, in order to construct milling Machine Wood, be sure to need an electric motor. This item may be several types.
The first type of engine that can be used in the manufacture of the machine with their own hands is asynchronous. The advantage is that it does not require maintenance, and will also allow working with a larger cutter. From disadvantages can be allocated a large number of Noise that makes the engine when working. However, there is already a question purely individual.
Collective engine. This option is somewhat worse than the previous one, for the reason that, over time and work, it is abrained by the brushes that have to change. The greater and more intense the engine is operated, the more often the brushes will have to be changed.
Engine power
Select the engine type for homemade machine Do with your own hands - it's not all. You need to pay attention to the power of this element. This is a very important indicator.
Machines with a capacity of up to 0.5 kW are best suited for surface treatment. It is worth adding that only the softest wood species can be processed on such a machine and use only small cutting tools.
The second type of engine power for a homemade machine with their own hands is 1.2 kW. As practice shows, this indicator is the most versatile and in demand. This power is enough for deep wood processing. For home use 1.2 kW is enough.
The last type of power is up to 2 kW. Most often, such machines are already semi-professional. They open up wide wood processing opportunities, almost any types of mills can be used, as well as process some types of plastic and soft metal - aluminum.
Number of revolutions and food workbench
If we talk about the number of revolutions for a homemade machine with your own hands, then everything is quite simple and understandable. The higher the numeric indicator of this characteristic, the cleaner and more efficient will be the final processing of the tree. However, there is another small plus. If the speed is high enough, then such an engine is not terrible such such defects like swirls. The mill will take them without any problems.
With meals, too, everything is quite simple. Most often, those engines are chosen from 220/50. Installing and connecting this type of engine does not cause problems. Several more difficulties occur when connecting elements with three-phase power.
Workbench and Frame for Aggregate
Made with your own hands the machine on the tree must necessarily have such an element as a workbench. The choice of its size should be based on what details will have to work in the future. The dimensions of the table, to which all this will be mounted, do not matter much.
The frame for the machine must be chosen so that it is not just very strong, but also stalling could carry dynamic loads. The main difference between the machine collected by its own hands is electric from manual in the fact that the device itself will not move, but the workpiece will have to actively move. From a practical point of view, the use of wood for the machine frame is not best idea. All due to the fact that over time the tree is drying, covered with cracks and loses its strength. The most optimal option will be a metal tube that has a square or rectangular profile.
Table top
When this item is selected, everything is exactly like with the frame, but on the contrary. Metal will be ne. the best choice As a starting material for two reasons. First, the countertop will be very massive and will have too rough look. Secondly, you will have to use welding to securely secure.
It is best to use one of the following three materials:
- planed boards;
- slabs from chipboard, army;
- multilayer Phaneur.
Material for the tabletop must be quite strong to withstand subsequent loads. For this reason, the thickness and material for the manufacture of this element should be chosen, relying on what work will be carried out in the future. Another important detail is a smooth surface of the table. If you do not comply with this recommendation, it will not be possible to make an accurate mill. If it is important to assemble a homemade machine with your own hands so that it can be done by decent quality of the workpiece, then this is one of the most important conditions.
In order to provide a perfectly smooth surface, you can use in such ways as: lamination, leaf upholstery or an accurate fit of planed boards.
How to make the machine with your own hands
The order of assembling this device begins with the fact that it is necessary to determine the location of the engine. Best option It is considered to install this element under the table. On the shaft of the engine, which must be directed vertically up, have a mill. In order to facilitate the order of assembly, it is best to make a drawing of the machine with your own hands, on which all the details were depicted in advance.
The last was quite productive in terms of different crafts. All summer was the work immediately above the three projects: a new model of the ski lift, a generator and a stone-striking machine. Today I will tell you just about the stonecraft. This machine is needed to my brother, seriously the fondant petrified trees. In the future, this machine will be intended for sawing fossil trees.
Before the start of work in my location there were photos of similar machines, it was possible to visit the stone workshop, where the operating machine was shown. I well represented the device and the principle of operation of this machine, thought out the design of the homemade machine. I wanted to make a convenient and compact machine, I think, as a result, it turned out.
Brother has already had some workers: a single-phase engine with a capacity of 0.75 kW was acquired, the hub is turned out for bearings and a shaft. The engine and hub were located on one platform.
The hub was made with a large margin of strength, and as a result, there were considerable dimensions. Because of this, a significant part of the saw blade is "eaten", and the discs of large diameter are expensive. I decided to make the hub of my own design, using the UCP-205 hull bearings. These bearings have proven themselves in operation of the ski lift.
Rama is welded from corners and a rectangular profile. Rama reminds rectangular parallelepiped. Overall dimensions of frame 600 * 400 mm.
After making a frame cut out of 3mm billets for a future tank under water. The tank with water is designed to cool the saw disk.
The final layout of the machine nodes began.
True, during the work, it was necessary to cut off one rack, because it prevented the electric motor pulley. In the future, the rack was replaced by the corner. And in general, the racks could also be made from the corners.
After carrying out the main welding and assembly works, the future machine looked like this.
As already wrote above, the hull Bearings UCP-205 were used in the hub. The shaft is sharpened from the semi-axis of the car ZIL-157. True, the workpiece had to be burned, turning machine No teeth had such an axis. Here I immediately remembered the Soviet quality.
Having made the necessary calculations, it came to the conclusion that the engine revolutions would be enough to cut the stone and the disk will not split, so the transmission is 1: 1. A tripartuous aluminum pulley of the shaft of the motor motor-block was purchased. From this pulley were made two pulleys for the stone machine.
The tabletop machine is made of 3 mm of leaf iron. The table top is attached to the frame with 17 M6 bolts. Botes with a secret head, and the openings of the required diameter and depth are drilled on the worktop, thanks to this, the caps are not exhibited above the surface.
So looked the machine after the first painting. Painting with the use of an aerosol cylinder.
The side walls of the machine are closed with a stainless steel grid with a shallow cell. The grid is fixed with aluminum corners and M6 bolts.
It has come important moment - Testing machine. In the photo and video, the first cutting of the fossil tree on this stone-cutting machine.
Small modifications are coming: installing a protective visor above the saw disk, installation of protective casing for an electric motor. Do not forget about the ground when working with this machine, all the same water is next to the engine.
During the first test, it turned out that the water into the tank should be poured quite a bit, so that the saw blade goes into water by 5-10 mm, otherwise there is a strong splashing of water and work on the machine becomes dangerous.
On this stonecraft machine, when using a large saw blade, you can cut the blanks with a thickness of up to 90 mm. The water tank is removable, it is necessary for washing the tank from the residues of the stone particles.
