Method of machining opposite ends of rod members

摘要

A method of efficiently cutting and machining opposite ends of rod members in sequence is provided, which comprises steps of: abutting a grinding wheel (5) against the periphery of a long rod material (10a) placed at a predetermined work position; moving the grinding wheel towards and along the axis of a first portion of the long rod material (10a) in rotation to taper the tail end of the first portion (to be provided as 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 off, the sequence of these steps is repeated as needed.

1. A method of machining opposite ends of round rod members, comprising steps of:
moving a long round rod material to a predetermined work position; abutting a rotating disk-shaped grinding wheel on the periphery of the long round rod material in rotation; moving the grinding wheel towards, and along, the axis of the long rod material to chamfer a first portion of the long rod material on the front side the grinding wheel; cutting and chamfering the long rod material by moving the grinding wheel towards the axis of the long rod material at a predetermined position of the first portion to cut said first portion off the long rod material, and at the same time to chamfer the leading end of a second portion of the long rod material in contact with the rear side of the grinding wheel; moving the chamfered second portion of the long rod material to the work position after removing the first cut portion away from the work position; and repeating the above-mentioned steps as needed.
