Description

Laser cutting machine for plate processing

Technical field

The invention relates to a spring compression machine, in particular to a laser cutting machine for processing plates.

Background technique

Laser cutting 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 workpiece surface to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam will melt or gas The metallized metal is blown away, and as the relative position of the beam and the workpiece moves, the material is finally slit, so as to achieve the purpose of cutting. The laser cutting process replaces the traditional mechanical knife with an invisible beam.
