The high power density laser beam is used to irradiate the cut material. The material is heated to vaporization temperature quickly and evaporates to form a hole. As the beam moves to the material, the hole continuously forms a narrow cut or perforation, which completes the cutting of the material.
Laser cutting is to replace the traditional mechanical knife or difficult processing technology with invisible beam. It has high precision, fast cutting, not limited to cutting pattern, automatic typesetting saves material, smooth cut, low processing cost. Environmental protection and other characteristics, will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutting head has no contact with the workpiece and will not cause scratching on the workpiece surface in the work, the laser cutting speed is fast, the cut is smooth and smooth, and generally no subsequent processing is required. The cutting heat affected area is small, the plate deformation is small, the cut joint is narrow (0.1mm~0.3mm) or more fine, the notch has no mechanical stress and no shear burr, the machining accuracy is high, the repeatability is good, the material surface is not damaged. NC programming, can process arbitrary plan, can be a very large size of the whole board cutting, no need to open the mold, economical and time saving.
