[0002] Mechanical polishing relies on the grinding and rolling action of very fine polishing powder to remove an extremely thin layer of metal from the polished surface of the specimen. Generally, oilstone bars, wool wheels, sandpapers, etc. are used, mainly by manual operation. For special parts such as the surface of a rotating body, auxiliary tools such as a turntable can be used.
