CHAMFERING MACHINE FOR PROVIDING OPTIMAL OPERATION CONDITION DURING OPERATION OF CUTTING SURFACE OF CIRCULAR MATERIAL AND SURFACE CUTTING METHOD

摘要

Disclosed is a chamfering machine which enables a smooth cutting operation by allowing a workpiece to be fixed to a position corresponding to an optimal cutting condition. The chamfering machine comprises a cutting position groove, which is formed in the bottom surface of an upper guide, and into which a part of the outer circumferential surface of a workpiece is inserted, wherein the central part of the cutting position groove is formed to correspond to the cutting end of a chamfering cutter. The machining method is configured such that the chamfering cutter enters perpendicular to a centerline direction of a circular material and, after entering while cutting, to a point where the cutting end of a cutting tip is in line with the centerline, rotates a tubular material or revolves the chamfering cutter around the tubular material and thus can cut the surface of the circular material.

主权项

1. A chamfering machine comprising:
a chamfering machine body having a chamfering cutter which is disposed perpendicularly to a central axis of a circular material, a workpiece to be processed, and chamfers or cuts a surface of the circular material by an outer periphery of the lower end thereof; and an upper guide coupled to a lower part of the chamfering machine body, wherein a cutting position groove in which a part of the outer peripheral surface of the circular material is inserted is formed on the lower surface of the upper guide, and the central portion of the cutting position groove is aligned with a cutting end of a cutting tip formed at the edge of the chamfering cutter.
