Background
The high-precision mirror polishing of the mold means that the surface of the material is plastically deformed by using a polishing sheet, a woolen sheet, a diamond polishing paste, or the like, and the protruding portion of the surface of the work is removed to obtain a smooth surface having a mirror-like effect. High precision mirror lapping is currently generally performed by hand, and repeated lapping is performed on the mold surface by manually holding the tool with the abrasive disc attached thereto, with very slow efficiency, wherein diamond lapping must be performed under as light a pressure as possible, particularly when polishing pre-hardened steel and polishing with fine lapping paste.
