ABSTRACT:
Two cylindrical polishing drums 2 and 2, each having a polishing work surface 2a on their outer circumference, are disposed at an interval smaller than the diameter of a workpiece 7. The polishing drums 2 and 2 are rotated at a required speed, and a chamfered edge 7a of the outer circumference of the workpiece held by a workpiece holding means 3a is pressed against both polishing drums at the same time to mirror-polish the edge 7a at two different points.
