FAQ

Answer: Depending on the shape of the workpiece, different widths and particle sizes of grinding wheels can be selected, and the speed of the grinding wheel should be controlled within a certain range. When it is too high, the grinding wheel damages quickly and has a short service life; When it is too low, the production efficiency is low, so the circumferential speed of the grinding wheel must be appropriate. The optimal circumferential speed for polishing metal materials such as cast steel, steel, nickel, and chromium is 18-30m/s, for polishing copper and its alloys, silver, and zinc it is 14-18m/s, and for polishing aluminum and its alloys, lead, tin, and plastics it should be 10-14m/s.
