Study of the compound polishing process on SnSb alloy moulds

By using a high-speed rotating tool system made by a traction drive technique and the electrochemical–mechanical–magnetic compound process on a numerically control machine tool, SnSb alloy moulds are polished with ease. This greatly improves the polishing efficiency and the quantity of SnSb alloy moulds, without processing defects such as burning, scraping and workpiece hardening on the surface of the moulds.
