Description

Technical Field

[0001] The utility model relates to a cutting structure of a laser cutting machine, belonging to the technical field of laser cutting machines. Background Art

[0002] Laser cutting machine is to focus the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material is eventually cut, thus achieving the purpose of cutting.

[0003] During the cutting process of the laser cutting machine, some of the slag will splash when the high-pressure gas blows away the slag. When the slag splashes onto the cutting nozzle, it is very easy to stick to the cutting nozzle, thus affecting the cutting effect and cutting quality of the cutting machine. Utility Model Content
