Laser cutting uses an invisible beam to replace the traditional mechanical knife. It has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth cuts, and low processing costs. It will gradually improve or replace Traditional metal cutting process equipment. The mechanical part of the laser head has no 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, and generally does not require subsequent processing; the cutting heat-affected zone is small, the plate deformation is small, and the cutting slit is narrow ( 0.1mm~0.3mm); the incision has no mechanical stress and no shearing burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plan view, and can cut the entire board with a large format, without Opening the mold is economical and time-saving.
