Abstract
A method of efficiently cutting and machining opposite ends of rod members in sequence is provided, which comprises steps of: abutting a grinding wheel () against the periphery of a long rod material () placed at a predetermined work position; moving the grinding wheel towards and along the axis of a first portion of the long rod material () in rotation to taper the tail end of the first portion (to be provided as a rod member); and then moving the grinding wheel () further towards the axis of the rod material () 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 off, the sequence of these steps is repeated as needed.
