What are the causes of grinding cracks? BKCNC

The formation of grinding cracks is related to the hardness of the workpiece. Although burns may occur on workpieces with hardness less than 55 HRC, grinding cracks are rarely produced, and the possibility of grinding cracks is greatly increased for workpieces with hardness above 60 HRC. The measured hardness of the part is 59-60 HRC, which
