Abstract

See full text

Position adjustments of a chamfering cutter and a deburring cutter in a chamfering device with respect to a workpiece can be easily carried out. The chamfering device has a chamfering cutter, a deburring cutter which has a diameter different from that of the chamfering cutter; a cutter swing block, a cutter longitudinal feed block, and a base block, which rotatably support the chamfering cutter and the deburring cutter and are capable of subjecting the chamfering cutter and the deburring cuter to position adjustment with respect to the workpiece. The longitudinal feed block can perform single-axis feeding with respect to the workpiece. The chamfering cutter and the deburring cutter are disposed so that the cutting change amount of the chamfering cutter and that of the deburring cutter will be approximately equal to each other throughout the diameter range of the workpiece to be processed.
