PROBLEM TO BE SOLVED: To improve machining efficiency by providing work holding means holding and rotating disk-like works having chamfered outer peripheral edges on the surface and the back face and bringing the edges of the works into contact with multiple polishing drums simultaneously. SOLUTION: Three work holding means 12 are radially arranged at intervals of 120 deg. to surround the periphery of three polishing drums 11 on a rotary table 10 so that each work holding means 12 is located just in the middle between two adjacent polishing drums 11. Each work holding means 12 holds a disk-like work 1 having outer peripheral edges 1a, 1b chamfered at the angle θ on the surface and the back face, rotates it around the axis, and brings the outer peripheral edges 1a, 1b of the work 1 into contact with the work faces of two adjacent polishing drums 11 simultaneously. |
