PURPOSE:To provide a cutting work device capable of manufacturing a pipe member applicable to various types of precision machines by simultaneously cutting the outer peripheral surface and the inner peripheral surface. CONSTITUTION:An outside diameter bearing 8 and an outside diameter cutting blade 9 are parallely arranged inward on an outside diameter rotor 2 rotatably attached to an outside diameter main body 1, and an inside diameter bearing 16 and an inside diameter cutting blade 17 are parallely arranged outward on an inside diameter rotor 4 rotatably attached to an inside diameter main body 3. And respective rotors 2, 4 are rotated in the state where the outside diameter bearing 8 and the outside diameter cutting blade 9 are respectively faced to the inside diameter bearing 16 and the inside diameter cutting blade 17 at the specific distances, and the outer peripheral surface and the inner peripheral surface are simultaneously cut by respective cutting blades 9, 17 by facing tube members (a) to each other at the specific distances, and also they are simultaneously specular-finished by respective bearings 8, 16. |
