Laser cutting machine is atechnological revolution in sheet metal processing, and it is the"processing center" in sheet metal processing; laser cutting machinehas high flexibility, fast cutting speed, high production efficiency, and shortproduct production cycle, which has won wide acclaim for customers. market, theeffective lifetime of the technology.
Laser is to use matter excitationto generate light. This kind of light has a strong temperature. When itcontacts the material, it can quickly melt on the surface of the material,forming a hole, and forming a cutting according to the movement of the point topoint. Therefore, such a Compared with the traditional cutting method, thecutting method has a smaller gap and can save most of the materials. However,according to the definition and analysis of the cutting effect, the cuttingeffect of the material cut according to the laser can be satisfactory and theaccuracy is high. This is the inheritance In addition to the advantages of laser,it is also unmatched by ordinary cutting methods. Compared with traditionalcutting methods, laser cutting is easier to understand and learn, and hasabsolute advantages in terms of processing effect and speed required bymerchants. Therefore, it is believed that in the choice of cutting methods inthe future, laser cutting machines will be the needs of the public.
Laser welding is a high-efficiencyprecision welding method that uses a high-energy-density laser beam as a heatsource. Laser welding is one of the important aspects of the application oflaser material processing technology. In the 1970s, it was mainly used forwelding thin-walled materials and low-speed welding. The welding process isheat conduction, that is, the laser radiation heats the surface of theworkpiece, and the surface heat diffuses to the inside through heat conduction.By controlling the width, energy, peak power and repetition frequency of thelaser pulse and other parameters to melt the workpiece and form a specificmolten pool.
Laser has the characteristics ofhigh intensity, high energy density, strong focus, and good directionality.Laser cleaning technology uses three effects of laser pulse vibration, thermalexpansion of particles, photodecomposition or phase change of molecules ortheir combined effects to overcome pollution. The binding force between thesubstance and the surface of the substrate makes the dirt detach from thesurface to achieve the purpose of cleaning.
Laser cleaning is a"green" cleaning method that does not need to use any chemicals orcleaning fluids. The wastes that are cleaned are basically solid powders, smallin size, easy to store, recyclable, and can easily solve the problems caused bychemical cleaning. Environmental Pollution;
The basic principle of laser marking isthat a highenergy continuous laser beam is generated by a laser generator, andthe focused laser acts on the printing material to instantly melt or evengasify the surface material. By controlling the path of the laser on thesurface of the material, a Graphical markup required.
Laser marking is characterized bynon-contact processing, which can be marked on any special-shaped surfacewithout deformation and internal stress on the workpiece. It is suitable formarking metal, plastic, glass, ceramics, wood, leather and other materials.
