At present, the polishing technology of metal surface mainly includes chemical polishing, electrolytic polishing, mechanical polishing and composite polishing between them. Chemical polishing is a polishing process completed by chemical etching. It is characterized in that it does not need DC power supply and conductive hangers, and can polish workpieces with complex shapes and various sizes, but the service life of the solution is short, and it is difficult to ensure the concentration of the solution; while electrolytic polishing It is the process of putting the workpiece into a specific solution for anodic electrolysis to make the surface of the workpiece smooth and produce a metallic luster, but it pollutes the environment and cannot remove defects such as macroscopic scratches and pitting on the surface of the workpiece; mechanical polishing is through grinding The treatment process for obtaining a smooth surface by machining. Traditional surface treatment methods for metal materials include planing, milling, electric spark, wire cutting, etc. Usually, the surface roughness Ra value obtained by these processes is greater than 10 μm, and high-precision grinding machines are used.
