General principles of the stone cutting machine
The main elements of the stone cutting machine are:
- Steel shaft on which the cutting blade is attached;
- Pulley and belt connecting electric motor and shaft;
- Platform on which the sawn material moves.
The principle of its operation is no different from the machine for wood, with the only consideration that the stone is much harder than wood, so you need to know some special techniques. A diamond saw saws a stone at a speed of 5 millimeters per minute, and harder and more viscous materials are slower.
Note! For normal sawing, the shaft must be rigid and not bend, and the bearings must give the accuracy of rotation.
At work to keep a stone more than 50 millimeters in volume is inexpedient and inconvenient. But natural material is very rarely a regular shape, so it does not have a flat area and stability. To fix it, special clamps are used, which protect the stone from shaking and turning. Clips are attached to the slide, which slides in the direction of the cutting disc. The stone is delivered gently and slowly, so that there is minimal contact between its surface and the cutting blade.
How does the system work?
Stone grinding can be done on ordinary glass with the use of abrasive powders. Only a few drops of water are necessary and a little powder is applied to the glass. Now you can start work. During the process, the powder is gradually added in small portions as the abrasive wears off, and water is poured in order to maintain the creamy mass. Cutting the stone with the transition from the coarse fraction to the smaller one, hands, glass and stone should be washed with soap and water and a brush, after all, if a small fraction of the grains of a large faction gets into the small fraction, all the work will be spoiled.
Important! All work should be carried out only in goggles.
This is one of the schemes of how the self-made stone-cutting machine works. There are many different types, schemes and designs of such machines, and they can be made from various materials at hand. They can be assembled from old motorcycle parts, lawn mowers and so on. For those wishing to make the machine independently, one of the designs of the machine for cutting medium-sized stones will be described below.
We assemble the tool by ourselves
As an engine in a stone cutting machine, it is possible to use an electric motor from a washing machine, 180-250 Watt and with the ability to develop 1500 rpm. With this data, the pulley can be two-stage with a gear ratio of 1: 1 and 1: 0.35.The first is more convenient for processing stone with abrasive material, which is fastened, the second - for quick work with bulk powder.
As a transmission, the wedge-type belt from Zaporozhets perfectly suits. The thread of fastening the faceplate can be both left and right, the main thing is that during the work under load the faceplate does not fly off the axis. The trough for collection of sludge should be twice as large as the faceplate, and its height is two centimeters higher. The rubber is attached to the side walls, so that a stone that accidentally jumped out of the hands did not break.
All work with the stone is done with the addition of water, but a special dropper is used only for working on faceplates with fixed abrasive. If the work is carried out with a bulk abrasive, then it is better to use the hotel bath for wetting. A stone-cutting machine with its own hands, made on this principle, is a simple and effective way to obtain the necessary blanks.
Note! You must always have enough drives in stock.
