The laser tube cutting machine uses the laser emitted by the laser, which is focused into a high-power density laser beam through the optical path system to irradiate the surface of the workpiece, so that the workpiece reaches the melting point or boiling point. As the relative position of the light beam and the workpiece moves, a slit is eventually formed in the pipe, thereby achieving the purpose of cutting. Since the outer surface of the pipe is curved, a clamping device is needed to fix it to prevent the position of the pipe from shifting during the processing, resulting in misaligned cutting, which affects the use of the pipe.
