Shaft parts are one of the typical parts often encountered in hardware fittings. They are mainly used to support transmission components, transmit torque, and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: optical shafts, stepped shafts, and special-shaped shafts, or into solid shafts, hollow shafts, etc.

[0003] The cylindrical grinding machine is mainly used for the grinding of the outer surfaces of workpieces such as cylindrical, conical, or other surfaces developed by generatrix, and the end faces of shaft shoulders. Among all grinding machines, the cylindrical grinding machine is the most widely used type of machine tool. It generally consists of a cast iron bed for the basic part, a workbench, a headstock for supporting and driving the workpiece to rotate, a tailstock, a grinding headstock for installing the grinding head (grinding wheel), a transverse feed mechanism for controlling the size of the ground workpiece, and electrical and hydraulic devices for controlling the movement of the machine tool components, etc.

[0004] In the prior art, during the grinding process of shaft parts, the control of grinding accuracy is not good, resulting in products with small outer diameter grinding not meeting the requirements of high-precision grinding. At the same time, due to the long-term friction with the surface of the product parts during rotation, the accuracy of the rollers is prone to decline, and new bearings need to be replaced and the surface of the grinding rollers needs to be repaired for accuracy. However, the component structure of the existing grinding machines is complex and difficult to replace, seriously affecting the processing efficiency and processing accuracy.
