[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones, abrasive belts, and free abrasives for processing, such as honing machines, superfinishing machines, abrasive belt grinders, grinders, and polishing machines. The main working parts and tools on a rolling mill that cause continuous plastic deformation of metals. The roll is mainly composed of three parts: the roll body, the roll neck, and the shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is installed in the bearing and transmits the rolling force to the frame through the bearing seat and the pressing device. After the metal rolling mill has been out of use for a long time, the roll may rust. When the rusty roll is working, it is easy to contaminate the processed metal, so the roll surface needs to be rusted.

[0003] The existing roller outer circle grinding is mainly carried out by grinding the rotating roller surface with a belt machine or a grinding wheel machine. The roller is arranged in a bearing frame and rotates at a uniform speed manually or driven by a motor to fit the grinding mechanism. During the grinding process, manual cooperation is required to control the movement of the grinding mechanism so that the grinding mechanism moves laterally along the roller surface to comprehensively grind the roller surface. It is also necessary to control the fitting pressure between the grinding mechanism and the roller surface to control the grinding amount of the grinding mechanism. The operator controls the action mainly based on experience and judgment, which leads to uneven grinding of the roller surface, poor roller surface molding quality, and certain defects.
