When the removal of the burr is completed by the burr removing means 90, the cutting means 60 moves forward to reprocess the round surface of the raw material P to form the round surface of the raw material P. Is complete.

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.
