CO2 laser cutting principle and technology characteristics

CO2 laser cutting is used CO2 laser beam focusing mirror to focus on the material surface melting, while the laser beam coaxial with the cutting of gas blown off by the molten material, and to the laser beam and Materials relative movement along a certain path to do to a certain shape kerf. Most suitable for CO2 laser cutting machine cutting thickness of <12 mm low carbon steel, <6 mm stainless steel, <4 mm of aluminum.

CO2 laser cutting machine, precision cut to ensure maximum capacity at the cutting quality of their products must meet the requirements of the standard ISO 9013-221, which is the highest of three standards of thermal cutting. The material used in accordance with national standards and gas, not dross; processing of stainless steel, aluminum alloy, the smooth cut surface without oxidation, sharp corners well. CO2 laser cutting width with a narrow incision (typically 0.1 ~ 0.5 mm), high accuracy (typically bore center distance error of 0.1 ~ 0.4 mm, profile size error 0.1 ~ 0.5 mm), cut a good surface roughness (Ra = 12.5 ~ 25μm general ) of the process characteristics, the incision were thin, cut and sewn on both sides of the parallel and perpendicular to the surface, generally do not need to slit processing to welding. CO2 laser cutting speed, such as the use of laser power 3 kW, 8 mm thick carbon steel cutting speed of 1.6 m / min, 2 mm thick stainless steel cutting speed of 3.5 m / min, and the cutting method of small heat-affected zone, deformation minimal.
