Grinding is often the final finishing process in the machining of parts. During the grinding process, fine cracks are often generated on the surface of the parts. These cracks not only improve the surface roughness, but also greatly reduce the fatigue strength and load of the material. ability. In general, once a grinding crack occurs, the part has to be scrapped. Therefore, it is extremely important to prevent the occurrence of grinding cracks.
