PURPOSE: To shorten the work time by chucking the center of a pipe and automatically performing the cutting and surface machining operation on the pipe rotating together with a chucking ring by use of a cutter and a facer.
CONSTITUTION: A pipe P proceeds on a pipe feed conveyor line 10, is chucked by a chucking ring at its center, and is supported rotatably in its peripheral direction. The timing for chucking the pipe P at its center is performed by determining the stop position of the pipe P with length measuring units 14, 16 composed of a pair of photoelectric tubes at the inlet of the conveyor line 10. When the pipe P is stopped, it is rotated around its axis by rotary drive rollers 22A, 22B connected to motors at front and rear ends, and the cutting and end surfacing is performed by pipe cutters 18A, 18B and facers 20A, 20B by means of control outputs from pipe cut control units 28, 30 based on the length information of the pipe P.
