Laser cutting is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material eventually forms a slit, thereby achieving the purpose of cutting.

Laser cutting replaces the traditional mechanical knife with an invisible beam, with the characteristics of high precision, fast cutting, no limitation on cutting pattern, automatic typesetting to save materials, smooth incision, and low processing cost. 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 work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm); the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plane diagram, and can cut a large whole plate without opening a mold, which is economical and time-saving.

As a new type of tool, laser equipment is increasingly used in various industries, including laser cutting machines, laser engraving machines, laser marking machines, laser welding machines, etc.

Laser cutting machines are mainly divided into metal laser cutting machines and non-metal laser cutting machines
