ROTATION PROCESSING MACHINE

PROBLEM TO BE SOLVED: To provide a rotation processing machine capable of delivering a cylindrical workpiece, a rotation support jig, and a cutting tool using the same revolving loader, and reducing time required for the stage change operation of the rotation support jig and the cutting tool.SOLUTION: A rotation processing machine 1 includes: a rotating device 2 which supports a cylindrical workpiece 8 through a rotation support jig 6 and rotates it; a processing device 3 which is mounted with a cutting tool 7 and processes the cylindrical workpiece 8; and a revolving loader 4 which revolves to make a plurality of grippers 5 face the rotating device 2 in sequence. The plurality of grippers 5 are capable of changing a height position where the cylindrical workpiece 8 is delivered to the rotating device 2, a height position where the rotation support jig 6 is delivered to the rotating device 2, and a height position where the cutting tool 7 is delivered to the processing device 3. The revolving loader 4 revolves each gripper 5 between an external delivering position 502 where the each gripper faces an external carriage and an inner delivering position 501 where the each gripper faces the rotation device 2.
