Mechanical polishing is a polishing method that obtains a smooth surface by cutting and polishing the surface of the material to remove the convex parts after polishing.
Generally, you use whetstone strips, wool wheels, sandpaper, etc., mainly manual operations, and special parts such as the surface of a rotating body , can use auxiliary tools such as turntable, the surface quality requirements can be used ultra-refined polishing method. 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. Using this technology can achieve a surface roughness of Ra0.008μm, which is the highest among various polishing methods. This method is often used in optical lens molds
