Hello, A. The laser cutting machine focuses the laser emitted by the laser into a laser beam with high power density 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 laser beam blows away the melted or vaporized metal. With the movement of the relative position between the beam and the workpiece, the material finally forms a slit, thus achieving the purpose of cutting.

B, the laser cutting process replaces the traditional mechanical knife with invisible light beam, which has the characteristics of high precision, fast cutting speed, automatic typesetting, material saving, smooth incision and low processing cost, and will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head is not in contact with the workpiece, and the surface of the workpiece will not be scratched when working; Laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is needed; Small cutting heat affected zone, small plate deformation and narrow cut (0.1mm ~ 0.3 mm); The incision has no mechanical stress and shear burr; High machining accuracy, good repeatability and no damage to the surface of the material; Numerical control programming can process any scheme, cut the whole board in large format, and it is economical and time-saving without mold opening.
