PURPOSE:To enable uniform and sure polishing of any complicated surface, by providing a polishing pad on a polishing surface corresponding to the surface form of the profile of a polished plate. CONSTITUTION:A cylinder 12 for reciprocation and a single-acting cylinder 13 are operated in connection with the reciprocation of a carriage 15 to move a polishing pad 5 back and forth relatively to a polished plate 2 secured on frames 3, 4. The polishing pad 5 is thrusted and slid on the profile 1 of the polished plate 2. As a result, the profile 1 of the polished plate 2 is uniformly and surely polished by the polishing surface of the polishing pad 5 whose surface form corresponds to that of the profile 1. |
