Currently commonly used polishing methods

Mechanical polishing is a polishing method that relies on cutting and plastic deformation of the material surface to remove the polished convex parts to obtain a smooth surface. Generally, oilstone strips, wool wheels, sandpaper, etc. are used, and the operation is mainly manual. Special parts such as the surface of the rotary body can be Using auxiliary tools such as turntables, ultra-precision grinding and polishing methods can be used if the surface quality is high. Super-precision polishing uses special abrasives, which are pressed against the surface of the workpiece to be processed in a polishing fluid containing abrasives to perform high-speed rotation. Using this technology, a surface roughness of Ra0.008 μm can be achieved, which is the highest among various polishing methods. This method is often used for optical lens molds.
