The high-power density laser beam is used to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the light beam moves over the material, the holes continuously form narrow slits to complete the cutting of the material. The laser cutting process replaces the traditional mechanical knife with an invisible light beam. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece and will not scratch the workpiece surface during operation.
