in recent years, the demand for laser cutting machine tools in China is rapidly increased, and the demand for the optical fiber laser cutting machine tools is remarkably increased due to the advantages of convenience in maintenance, low consumption cost, excellent cutting sections and the like.

the laser cutting machine focuses laser emitted from a laser into a laser beam with high power density through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach a melting point or a boiling point, and simultaneously, the high-pressure gas coaxial with the laser beam blows away the molten or gasified metal. And finally, the material is cut along with the movement of the relative position of the light beam and the workpiece, so that the cutting purpose is achieved. The laser cutting processing is to replace the traditional mechanical knife by invisible light beams, has the characteristics of high precision, quick cutting, no limitation on cutting patterns, automatic typesetting, material saving, smooth cut, low processing cost and the like, and can gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser tool bit is not in contact with the workpiece, so that the surface of the workpiece cannot be scratched in the working process; the laser cutting speed is high, the cut is smooth and flat, and subsequent processing is generally not needed; the cutting heat affected zone is small, the deformation of the plate is small, and the cutting seam is narrow (0.1 mm-0.3 mm); the notch has no mechanical stress and no shearing burr; the numerical control programming can be used for processing any plane graph, cutting the whole plate with large breadth without opening a die, and the method is economical and time-saving.
