After the apparatus has stopped and stayed at the retracted position for a predetermined stopping time, the apparatus is moved forwards again for a feed length of an intermittent cutting from the position where the cutting was once interrupted. Thereafter the above process of retract movement from the end of the steel pipe is repeated to perform machining of the end of the steel pipe to form a desired amount of chamfer.
