[0002] In current life and industrial applications, some workpieces or metal surfaces need to be smooth and clean, which requires polishing of the workpiece or metal surface. Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and flat surface. Polishing is mainly divided into chemical polishing and mechanical polishing. Among them, mechanical polishing is divided into dry polishing and wet polishing. In the wet polishing process, the equipment investment is large, the brightness is dim, the polished product has good mirror surface and no directionality, and the generated dust can flow out with the polishing liquid, which is convenient for handling. Generally, a grinding head is installed on the CNC polishing machine to polish the processed metal surface. The CNC polishing machine is a device used for polishing and grinding the surface of the workpiece, and is widely used in the surface treatment of various metals and non-metallic materials.
