Generally speaking, the working environment of diamond saw blades is relatively harsh. The primary use of diamond saw blade products is cutting stone, which is widely used in cutting marble, granite, ceramic wall and floor tiles and concrete products. It is the primary processing equipment in the stone and building materials industry.

Circular saw blade cutting has the advantages of convenient operation, high efficiency and good processing quality. But the noise is high and the rigidity of the blade is poor. During the cutting process, the saw blade is prone to oscillation and deviation, resulting in poor parallelism of the workpiece being cut. Sawing machine spindle can not bear relatively large cutting force, which makes the cutting process oscillate, but can not cut straight line. Although increasing the thickness of saw blade can improve its rigidity, it is still difficult to guarantee the parallelism of the slices. In addition, the increase of thickness not only increases the cost of saw blade, but also increases the width of saw slot and reduces the yield. The linear speed of circular cutting is relatively high, up to 50 meters per second. The cutting depth is limited by the diameter of the saw blade. Generally, it does not exceed one third of the diameter, and generally does not exceed one meter.

Diamond grain size is the key to the quality of diamond saw blades, which is the most important index to check the wear resistance and sharpness of diamond saw blade.
