Using auxiliary tools such as turntables, ultra-fine grinding and polishing methods can be used for high surface quality requirements. Ultra-fine polishing uses a unique abrasive tool, which is pressed against the surface of the workpiece to be processed in a polishing liquid containing abrasives for high-speed rotation. The surface roughness ...

Magnetic Grinding and Polishing. Magnetic grinding and polishing typically use magnetic abrasive to form abrasive brushes under the action of the magnetic field to grind the workpiece. The process is highly efficient, easy to carry out, and controllable. With an appropriate abrasive, the roughness of the surface can get achieved up to Ra 0.1μm.
