To obtain high-quality polishing effect, the most important thing is to have a high-quality of the stone, sandpaper and diamond grinding paste polishing tools and aids. The choice depends on the pre-polishing process after processing the surface condition of numismatics slip Caizhuan mold, such as machining, EDM, grinding, and so on. General mechanical polishing process is as follows: (1) the surface after the rough polishing process by milling, EDM, grinding, etc., may choose the speed at 35 000-40 000 rpm rotary surface polishing machine or ultrasonic grinding machine for polishing. Commonly used methods are the use of diameter Φ3mm, WA # 400 wheels to remove layers of white sparks. Then hand Whetstone grinding Caizhuan mold, strip Whetstone add kerosene as a lubricant or coolant. 2) semi-fine polishing semi-fine sandpaper and polishing the main use of kerosene. Number of sandpaper were: # 400 to # 600 to # 800 to # 1000 to # 1200 to # 1500. (3) The main use fine polishing fine polishing diamond polishing paste.
