High-speed Rotating Polishing

- Aug 28, 2020-

When polishing, the high-speed rotating polishing wheel (with a circumferential speed of more than 20 m / s) presses the workpiece, which makes the abrasive roll and micro cut the surface of the workpiece, so as to obtain a bright machined surface, and the surface roughness can reach ra0.63-0.01 μ m generally. When the non greasy Matt polishing agent is used, the bright surface can be dulled to improve the appearance. In mass production of bearing steel balls, drum polishing is often used.
