Common knowledge of mold mirror polishing
Manual mechanical polishing: It is a polishing method that obtains a smooth surface by removing the polished convex parts by cutting and plastic deformation of the surface of the material. Generally, you use whetstone strips, wool wheels, sandpaper, etc., mainly manual operations, special parts such as rotating For the surface, auxiliary tools such as turntables can be used. For high surface quality requirements, ultra-refined polishing can be used. The ultra-precise grinding polishing adopts a special grinding tool. In the grinding polishing liquid containing abrasives, it is pressed against the surface of the workpiece to be processed for high-speed rotation.
