The laser cutting machine focuses the laser light emitted from the laser into a high power density laser beam through the optical path system. The laser beam is irradiated to the surface of the workpiece, so that the workpiece reaches the melting point or boiling point, and the high-pressure gas coaxial with the beam will blow away the molten or vaporized metal. The cutting tolerance of the laser cutting machine is generally around 0.1 mm. If it is a small format, the cutting tolerance is about 0.02 mm.
With the movement of the relative position of the beam and the workpiece, the material is finally formed into a slit, so as to achieve the purpose of cutting.
The laser cutting process replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting pattern limitation, automatic typesetting to save material, smooth incision, low processing cost and so on. It will gradually improve or replace the traditional metal cutting process equipment.
The mechanical part of the metal cutting laser cutter head is not in contact with the workpiece, and will not cause scratches on the surface of the workpiece during work. The laser cutting speed is fast, the incision is smooth and flat. After laser cutting, the product generally does not require subsequent processing. Laser cutting has a small heat-affected zone, small sheet deformation and narrow slits. The laser-cut incision has no mechanical stress and no shear burrs. Laser cutting has high processing precision, good repeatability, and does not damage the material surface. Laser cutting adopts numerical control programming, can process any plan, and can cut the whole board with a large format. It does not need to open the mold, which is economical and time-saving.
