Abstract

PURPOSE:To polish a work in correctness further with a fine finish, by comparing polished area of the work, adapted to a polishing surface, with preset area and changing polishing pressure in accordance with a change of said polished area. CONSTITUTION:A work 2 is moved through handles 4, 6 while pressing its side A to a pressure detector surface B, arranged with plural pressure sensors 1b of a pressure detector device 1a in a matrix state, and approximate area information relating to a position of the work is programmed through an encoder and stored to a RAM11. To approximately obtain contact area, a scanning circuit 10 is operated under control of a CPU13, and its output in a line direction is obtained through an amplifier 1c and comparator 1d and measured. Then at polishing, polishing pressure is changed on the basis of area information stored in said RAM11.
