Cracks on the surface of the diamond cutter head, which are longitudinally continuous or intermittently distributed on the surface of the steel, are mainly caused by residual cracks and subcutaneous defects in the blank. This situation will affect normal use. What will happen during work:
When the line speed is high and the cutting rate is fast, when the diamond and carcass are mainly affected by impact wear, the diamond with high grade, high strength, and fine-grained diamond and the carcass with high strength and good toughness are required when the line speed is low and the cutting rate is slow. When the diamond and the matrix are mainly worn by grinding, the diamond with lower strength and coarser grain size and the matrix with better wear resistance can be used. The speed of the general equipment is fixed, the linear speed of the saw blade is unchanged, and the speed of the cutting rate is controlled by the operator. Allow the cutting rate to increase. The cutting rate is equal to the product of the cutting amount and the cutting amount. When the cutting rate is the same, the cutting rate is large, and the cutting amount is small, which is beneficial to the diamond cutter head.
