APPARATUS FOR CUTTING CYLINDRICAL WORK AND METHOD FOR MANUFACTURING METAL RING

摘要

The present invention minimizes adhesion of dross on a cut portion at the time of cutting a cylindrical work by laser beam irradiation. At the time of cutting a rotating cylindrical work (W) using a laser beam, a machining head (200) is displaced in parallel from a position on a line (L1), on which the laser beam travels toward the rotating axis of the work, to a position on a line (L2) in the upstream in the rotating direction of the work.
