Method for polishing plate and apparatus therefor

摘要

Disclosed is a method for specular polishing the surface of a metal or non-metal plate (10) to be polished, especially a large-sized plate, in which the surface of the plate is polished by rotating a polishing member (9) via cranks (36, 37), while pressing the polishing member against the surface of the plate at a predetermined pressure. Since the polishing member is rotated via cranks, while being pressed against the surface of the plate at a predetermined pressure, the predetermined pressure is uniformly distributed over the entire surface to be polished, hence, precise and uniform specular polishing of even a large-sized plate is feasible. <IMAGE>
