PROBLEM TO BE SOLVED: To provide a spherical surface grinding/polishing instrument for grinding and polishing a spherical surface at the same time by inserting a processing object in the inside to be processed because the whole of a spherical shape can be polished but a part or several parts of a spherical surface can not be ground and polished at the same time.SOLUTION: A reversed elliptic-hemisphere-shape dug part having continuous curved surfaces different in curvatures are formed on an outer surface of an elevation surface body. Grinding/polishing function is applied to the inside thereof to form a processing object insertion guide groove. |
