違点を中心に説明する。(Second Embodiment) In an end machining apparatus for a cylindrical work according to a second embodiment, as shown in FIG. 3, a grinding wheel 2 of a cylindrical body is chamfered 23 at both ends in the axial direction. This is a difference from the first embodiment, and the following description will focus on the difference.

面取りを施し実施したものである。In the first embodiment described above, the cylindrical grinding wheel 2 having the same outer diameter is used as an example throughout the entire axial direction. Since it is necessary to remove the outer peripheral surface 22 from the processing surface of the cylindrical work 1, in the second embodiment, the reciprocating motion at the time of cutting is facilitated and the time required for the direction switching is reduced. Then, chamfering is performed at both ends in the axial direction.
