  • Laser cutting nozzle for a laser machining unit and method for operating such a laser machining unit
    Patent number: 12017303
    Abstract: A laser cutting nozzle for a laser machining unit is described, the nozzle including a passage for the laser beam and cutting gas. The passage extends between a nozzle inlet and a nozzle mouth along a passage longitudinal axis. The passage comprises a convergence portion and a divergence portion. In the entire divergence portion, the wall of the passage forms an angle of inclination relative to the passage longitudinal axis of at most 5°. In addition, the length of the divergence portion is less than 5 times the diameter of the constriction.

  • LASER CUTTING METHOD AND LASER CUTTING APPARATUS
    Publication number: 20230111969
    Abstract: A method for laser cutting a workpiece having a thickness of less than 6 mm includes the steps of directing a first laser beam, a second laser beam, and a gas jet at an entrance surface of the workpiece such that the first and second laser beams at least partially overlap one another on the workpiece. The first laser beam has a smaller focus diameter than the second laser beam, a beam parameter product of the first laser beam is at most 5 mm*mrad, and a power proportion of the second laser beam of a total laser power is less than 20%. A cutting kerf with a broken cutting edge is formed on the entrance surface of the workpiece.
