It is better to use diamond tools sintered by diamond for stone. Domestic diamond tools are developing in four directions in the field of stone processing: environmental protection, high efficiency, energy saving and professionalism. The commonly used diamond tools are as follows:
(1) Diamond slices, ultra-thin slices
Diamond slices and ultra-thin slices, which are mainly distinguished by the thickness of giant slices. Using thin slices and ultra-thin slices to process granite and marble plates can greatly improve the cutting efficiency and the yield of raw materials and reduce the power consumption.
(2) Frame saw Diamond frame saw, also known as diamond saw, is a new type of frame saw developed in 195s. In the developed stone technology, the diamond frame saw frame has basically replaced the sand saw, which has the advantages of fast cutting speed and high production efficiency; The processing quality is good, and the sawn plate is smooth and flat, which can save a rough grinding process; Save labor and steel, improve working environment and facilitate management.
(3) Super-large saw blade matrix with a diameter of more than 26mm
Many stone mine producing areas mainly adopt the backward method of drilling and blasting to collect stone wastes, which is not only inefficient in production, but also unsafe in operation, especially because of the rock mass fracture caused by explosion, which seriously damages the stone resources, and the mined wastes are irregular in size, even scrapped due to cracks, and the yield is very low. It is estimated that only 5% to 25% of the raw materials mined by drilling and blasting can be processed into timber. It has been paid more and more attention and widely used to mine stone waste with super-large saw blades.
(4) hollowed-out saw blade
Compared with the conventional saw blade, hollowed-out saw blade only processes several rows of holes on the blade body, and the shape of the holes is mainly water drop. Judging from the current use of the hollowed-out circular saw blade, the hollowed-out circular saw blade has the following advantages without any change in the sawing process: (1) it is easy to enter water, which obviously improves the cooling effect; (2) increased chip removal; (3) The weight of the saw blade and the running load of the sawing machine are reduced, and the current is reduced by 5 amps year-on-year; (4) reducing the operation noise; (5) Due to the weight reduction of saw blades, it is possible to load more saw blades on the small combined sawing machine; (6) the service life of the saw blade can be prolonged, the number of cutting square meters can be increased, and the welding deformation is small; (7) Using intermittence, the tension recovery performance is good. Using hollowed-out saw blade to process stone can not only greatly reduce the power consumption per square meter, but also improve the utilization rate of stone waste resources and improve the productivity of stone processing.
