Method of beveling plate-like metal member

摘要

A stamped-out plate-like metal member (1) for use as an element of a belt in a continuously variable transmission has a recess including an undercut (3d) therein. A stream of a liquid (14) mixed with particle members (13) is ejected toward an edge (3a) to be beveled of the recess thereby to bevel the recess. After the edge (3a) is beveled by deburring the edge, the recess is finished by removing a bulge (3c) formed on an outer surface of the edge by deburring the edge.
