technical field

The invention relates to the field of laser cutting machinery, in particular to a laser cutting workbench.

Background technique

The laser cutting machine focuses the laser light emitted from the laser device into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece 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. With the movement of the relative position of the beam and the workpiece, the material will eventually form a slit, so as to achieve the purpose of cutting.

Laser cutting process replaces the traditional mechanical knife with an invisible beam.
