The principle of laser cutting: Laser cutting is to focus the laser beam on the surface of the material with a focusing mirror to melt the material, and at the same time use the compressed gas coaxial with the laser beam to blow away the melted material, and make the laser beam and the material follow a certain trajectory. Relative movement, thus forming a certain shape of the slit.
Application fields of laser cutting: machine tools, engineering machinery, electrical switch manufacturing, elevator manufacturing, grain machinery, textile machinery, locomotive manufacturing, agricultural and forestry machinery, food machinery, special vehicles, petroleum machinery manufacturing, aerospace, environmental protection equipment, household appliances manufacturing, Various machinery manufacturing and processing industries such as large motor silicon steel sheets.
Application range of laser cutting processing
Most laser cutting machines are controlled by CNC programs or made into cutting robots. As a precision processing method, laser cutting can cut almost all materials, including two-dimensional cutting or three-dimensional cutting of thin metal plates.
In the field of automobile manufacturing, the cutting technology of space curves such as car roof windows has been widely used. Volkswagen of Germany uses a fiber laser with a power of 2000W to cut complex-shaped body sheets and various curved parts. In the field of aerospace, laser cutting technology is mainly used for cutting special aerospace materials, such as titanium alloy, aluminum alloy, nickel alloy, chromium alloy, stainless steel, beryllium oxide, composite materials, plastics, ceramics and quartz. The aerospace parts processed by laser cutting include engine flame tube, titanium alloy thin-walled casing, aircraft frame, titanium alloy skin, wing stringer, tail panel, helicopter main rotor, space shuttle ceramic insulation tile, etc.
Laser cutting forming technology is also widely used in the field of non-metallic materials. Not only can it cut materials with high hardness and high brittleness, such as silicon nitride, ceramics, quartz, etc.; it can also cut and process flexible materials, such as cloth, paper, plastic board, rubber, etc., such as clothing cutting with laser, can save 10% of clothing material % to 12%, increasing the efficacy by more than 3 times.
