LASER CUTTER AND LASER CUTTING METHOD

摘要

PURPOSE:To allow the execution of cutting with high accuracy by providing a rotating mechanism which subject the laser beam to be projected to a work to precession at the point just before the processing surface of the work of an induction means. CONSTITUTION:The laser beam 9 is applied from a laser oscillator to a head 4 of the laser cutter. The work 2 is imposed on a moving table and is moved. The laser beam 9 is guided and condensed by a bending mirror 10, a beam parallel 13 and a condenser lens 11 to the work 2. The irradiation with the laser beam 9 and the movement of a moving table are controlled by a control means. The rotating mechanism which subject the laser beam 9 to be projected to the work 2 to the precession is provided at the point just before the processing surface of the work 2 of the induction means. The generation of the taper cut surface is obviated in this way.
