The laser cutting machine is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the work piece to make the work piece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.
As the relative position of the beam and the work piece moves, the material will eventually form a slit, so as to achieve the purpose of cutting.
Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting, saving materials, smooth cuts, and low processing costs. It will be gradually improved or replaced. Traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the work piece, and will not scratch the surface of the work piece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally does not require subsequent processing; the cutting heat affected zone is small, the plate deformation is small, and the slit is narrow ( 0.1mm~0.3mm); the incision has no mechanical stress, no shearing burr; high processing accuracy, good repeatability, no damage to the surface of the material; CNC programming, can process any plan, can cut the entire board with a large format, without Opening the mold saves time and economy.
Compared with traditional oxyacetylene, plasma and other cutting processes, laser cutting speed is fast, the slit is narrow, the heat-affected zone is small, the edge of the slit is perpendicular, and the cutting edge is smooth. At the same time, there are many types of materials that can be laser cut, including carbon steel, Stainless steel, alloy steel, wood, plastic, rubber, cloth, quartz, ceramics, glass, composite materials, etc. With the rapid development of the market economy and the rapid development of science and technology, laser cutting technology has been widely used in automobiles, machinery, electricity, hardware, and electrical appliances. In recent years, laser cutting technology is developing at an unprecedented speed, with an annual growth rate of 15% to 20%.
