Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine with a protective structure for precision mechanical processing. Background Art

[0002] The laser cutting machine focuses the laser 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 its melting point or boiling point. 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, a cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] For example, the Chinese utility model provides a patent number of "a laser cutting machine with good protection effect for precision machining": CN 216177651 U, which includes a laser cutting machine body, the right side of which is fixedly connected to an electrical control box, and both sides of the top of the laser cutting machine body are provided with a second walking mechanism, and the first walking mechanism is provided on the side opposite to the two second walking mechanisms.
