PURPOSE:To obtain a desirable finished surface having high accuracy by attaching an elastic polisher which does not contain grinding grain and has a Young's modulus over a specific value or more onto a work under pressure and supplying the abrasive liquid which contains minute free grinding grains, under permitting relative movement of the polisher. CONSTITUTION:A work 11 having a Ni-p plated surface having a flatness of (a) is attached onto an elastic polisher 13 which is made of phenol resin and consists of a network structure having gas holes 12 and possesses a Young's modulus of 10<4>g/mm.<2> or more, and the work 11 is surface-polished by supplying the abrasive liquid 16 containing the free grinding grains having a grain diameter of 1mum or so from an abrasive-liquid feeding pipe 15, pressed by a weight 14. In this case, it is necessary to use a polishing tool having a large Young's modulus in order to obtain the high plane accuracy of the work, and the gas hole in the elastic polisher serves to remove working scrap, and the favourable surface poslishing is permitted. Therefore, with this method, the surface of the work which has high accuracy can be obtained, and the desirable finished surface can be obtained at the same time. |
