DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of chamfering an edge of a rod-shaped body such as a round bar, a pipe, a wire rod (wire material) by bringing the end portion into contact with a rotary polishing portion of a rotary polishing device. The present invention relates to a rod end processing apparatus for polishing an end face.
