END PROCESSING MACHINE OF PIPE

PROBLEM TO BE SOLVED: To provide a pipe end processing machine capable of processing a pipe without rotation, making the machine small and light by using only one drive part, and feeding cutting tools at a constant feeding amount. SOLUTION: This pipe end processing machine 10 grinds a spacer receiving face 50 by a cutting tool 18 by rotating a turntable 14 by driving an air motor 16. When the turntable 14 rotates, a feed screw 20 is intermittently rotated by a 1-tooth rotation action of a sprocket 22 by a pin 24. Thereby, a cutting tool holder 92 screwed with the feed screw 20 is moved in a radial direction of the turntable 14 along a groove 90, and the cutting tool 18 held by the cutting tool holder 92 is moved toward an inner peripheral position from an outer peripheral position. By the movement of the cutting tool 18, the entire spacer receiving face 50 of a flange 48 is ground with the cutting tool 18, so as to process the spacer receiving face 50 flat.
