For many mechanical and electrical manufacturing industry, modern computer program controlled laser cutting system to facilitate the cutting of workpieces of different shapes and sizes, it is more often than punching, molding process is preferred; despite its processing speed is slower than the punches. but it does not mold consumption, no need to repair the mold, while also saving to replace the mold time, thus saving processing costs, reduce production costs, so the overall consideration is more cost-effective. Laser cutting is a high energy density controllability of good non-contact processing. Laser beam is focused to form a very small point of strong energy, it used in cutting many of the features. First, the laser light energy to convert the amazing heat retention in a very small area can provide (1) narrow straight edge slotted; (2) The minimum heat-affected zone adjacent a cutting edge; (3) very small local deformation. This kind of Laser pointer has two models suitable to different locations. 
Laser cutting a wide range of adaptability and flexibility. Compared with other conventional methods of processing, laser cutting and greater adaptability. First, compared with other thermal cutting methods, the same as a thermal cutting process, other methods can not be like a laser beam as the role of a very small area, resulting in wide incision, the heat-affected zone and obvious deformation of the workpiece. Laser cutting non-metallic, and other thermal cutting methods can not be. Laser cutting of the main process. High power density laser beam heating, the surface temperature rose to the boiling temperature of the speed is so fast enough to avoid melting caused by heat conduction, so part of the material vaporized into steam to disappear, part of the material as ejecta from the kerf bottom The auxiliary gas flow blown away. The manager explained the easy manipulation function of this kind of Laser pointer .
When the incident laser beam power density exceeds a certain value, the beam irradiation point inside the material begins to evaporate, and the formation of holes. Once such a small hole is formed, it will absorb all of the incident beam energy as a blackbody. Holes surrounded by the molten metal wall, then the beam coaxial auxiliary air holes around the molten material away. With moving parts, holes synchronous traverse the cutting direction to form a kerf. The laser beam is to continue along the slit cutting-edge radiation, continuous or pulse of the molten material to be blown away from the seam inside. The general use of inert gas melt cutting, replaced by oxygen or other reactive gases, materials under the irradiation of the laser beam was ignited fierce chemical reaction with oxygen to produce another heat source, known as the oxidation of the melt cutting. The working time of Laser pointer can be calculated accurately.
