Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a non-metal laser cutting machine. Background Art

[0002] A laser cutting machine uses laser light emitted from a laser source, focused through an optical system into a high-power-density laser beam. The laser beam strikes the workpiece surface, causing it to reach its melting or boiling point. As the beam and workpiece move relative to each other, a slit is formed in the material, achieving the desired effect. Laser cutting replaces traditional mechanical knives with invisible beams. It offers high precision, fast cutting speeds, unlimited cutting patterns, automatic layout to save material, smooth cuts, and low processing costs. It is poised to gradually improve upon or even replace traditional metal cutting equipment.

[0003] During use, the laser cutting machine needs to cool the cutting head to ensure its high working efficiency. Currently, water cooling is mostly used to cool the cutting head, which is a single method and has poor effect. Therefore, it is necessary to provide a new technical solution to overcome the above defects. Utility Model Content
