Description

Technical Field

[0001] The invention relates to the field of laser cutting machinery, in particular to a laser cutting workbench. Background Art

[0002] Laser cutting machine 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 surface of the workpiece, causing the workpiece to 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. As the relative position of the beam and the workpiece moves, the material is eventually cut, thus achieving the purpose of cutting.

[0003] Laser cutting replaces traditional mechanical knives with invisible beams. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It will gradually improve or replace traditional metal cutting equipment. The mechanical part of the laser cutter head does not contact the workpiece and will not scratch the surface of the workpiece during operation; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat-affected zone is small, the plate deformation is small, and the cutting seam is narrow; the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plane diagram, and can cut a large whole plate without opening a mold, which is economical and time-saving.
