Laser cutting is the laser beam emitted from the laser, through the optical path system, focusing on the high power density of lasers. The laser beam is irradiated to the workpiece surface, so that the workpiece reaches the melting point or boiling point, while the high-pressure gas with the coaxial beam is blown away by melting or gasification metal. With the relative position of the beam and the workpiece moving, the material is finally formed to cut the seam, so as to achieve the purpose of cutting.

Laser cutting is the use of invisible beam instead of the traditional mechanical knife, with high precision, cutting fast, not limited to cutting patterns, automatic typesetting saving materials, incision smoothing, low processing costs, will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter has no contact with the work, in the work will not cause scratches on the work surface, laser cutting speed, smooth incision, generally no need for subsequent processing; cutting heat affected area small, plate deformation small, slit narrow (0.1mm~0.3mm); the incision has no mechanical stress, no shearing burr; Good repeatability, no damage to the surface of the material, NC programming, can be processed arbitrary floor plan, can be a large-format plate cutting, no need to open the mold, economic province.

As a new type of tools, laser equipment is becoming more and more mature to various industries, including laser cutting machine, laser engraving machine, laser marking machine, laser welding machine, etc.
