Abstract

PURPOSE:To obtain a nodal ring generating no deformation in molding and lowered in the hardness of burr to simplify the removal of the burr in a post- process, by mounting a thin wall tube to a jig and cutting the same by laser beam. CONSTITUTION:A motor 29 wherein a thin wall short pipe 20 is mounted to the rotary jig 26 mounted on a table 27 movable in a uniaxial direction is rotated and the power of said motor is transmitted to the rotary jig 26 by a belt 30 and the laser beam 24 condensed by a lens 25 is allowed to irradiate the thin wall short pipe 20 while the rotary jig 26 is rotated. At this time, the movement of the table 27 is made synchronous to that of the motor 29 to form the focus of the laser beam on the thin wall short pipe 20. Further, a gas stream is given in the same direction as that of the irradiation with the laser beam. Further, a gas stream is given by connecting a gas pipe 28 behind the rotary jig 21 so as not to bond generated dross to the inner surface of the short pipe 20 so as to allow gas to pass through the thin wall short pipe 20. There is no deformation in a molded nodal ring and the processed hardened burr viewed at the time of press cutting is not observed and the shape accuracy of a part is enhanced.
