Laser cutting involves using a highly focused, high-power-density laser beam to照射 the workpiece, causing the material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed gas stream coaxial with the laser beam is used to blow away the molten material, thereby cutting the workpiece. Laser cutting is one of the thermal cutting methods.

Metal cutting machines are equipment that utilize laser technology for cutting. Many metal processing factories now use laser cutting machines to cut metal. Lasers are highly energetic light beams that can achieve rapid cutting in extremely short periods. Metal cutting machines are primarily used for the quick cutting of various metals, including carbon steel, silicon steel, stainless steel, aluminum alloys, titanium alloys, galvanized sheets, pickled sheets, aluminum-zinc coated sheets, and copper.
