Polishing

Mechanical polishing is a polishing method that obtains a smooth surface by cutting and plastic deformation of the surface of the material to remove the convex parts after polishing. Generally, using whetstone strips, wool wheels, sandpaper, etc. Using auxiliary tools such as turntables, ultra-precise polishing methods can be used for high surface quality requirements. Ultra-precision grinding polishing is 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 to reduce the surface roughness of the workpiece to obtain a bright and flat surface. .
