Means for Achieving the Object: The method comprises steps of abutting a grinding wheel (5) against the periphery of a long rod material (10a) placed at a predetermined work position and kept in rotation about its axis; moving the grinding wheel towards, and along, the axis of a first portion of the long rod material (10a) to taper the tail end of the first portion (to become a rod member); and then moving the grinding wheel (5) further towards the axis of the rod material (10a) to cut the first portion off the long rod material and at the same time chamfer the leading end of a second portion of the long rod material in contact with the rear side of the grinding wheel. After removing the first rod member cut (rod member) off the long rod material, the sequence of these steps is repeated as needed. |
