Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to an environmentally friendly cutting device for making billboards. Background Art

[0002] Billboards refer to all outdoor media that convey advertising information. When billboards are produced, laser cutting devices are needed to cut them to the appropriate size. 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 the 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 slit is eventually formed in the material, thereby achieving the purpose of cutting.
