Laser cutting is the use of high-power density laser beam to irradiate the cut material, so that the material is quickly heated to vaporization temperature, evaporation to form holes, as the beam to the material, the hole continuous formation width is very narrow (e.g. 0. 1mm or so) cut, complete the cutting of the material.
Laser cutting features: Laser cutting is precise because it is based on the “full flight light path” principle, it is the first condition to complete CNC processing. Laser cutting is a contactless processing technology that uses laser as energy. The laser beam focuses on its energy density of 105 to 108 watts per square centimeter, which is sufficient to vaporize and melt a variety of engineering materials. When cutting black metal, oxygen is sprayed simultaneously, oxygen reacts with metal oxidation, releasing a large amount of heat to cause the metal to melt further, while high-speed air flow can eliminate slag in the seam. Therefore, laser cutting has the advantages of fast cutting speed, small deformation of material, high precision and low noise.
Analysis of CNC processing technology: combined with the actual situation, such as some large-scale turbine generator projects, magnetic pole punch larger, plate waste on each side can only be left 5mm, even if the production of mold in the punch ingle processing, burrs, sheet thin and easy to deform, easy to produce waste parts, so laser cutting is the best choice. Laser cutting collection intelligent, precision, generalization, simplicity and so on, is the necessary condition stake for CNC processing, but also in the new era, the new era of better development of favorable factors.
