The metal laser cutting machine has the characteristics of high cutting accuracy and fast cutting speed, and its cutting pattern has fewer restrictions. Therefore, many customers are very optimistic about the metal laser cutting machine. So what is the working principle of the metal laser cutting machine? Let's give you a brief introduction. The laser cutting machine is a dense beam of light in the form of light with high concentration and high heat through the laser stroke. The beam irradiates the surface of the material, uses the high temperature generated to melt the material and uses the high pressure gas generated by the beam coaxial to remove the melted Exhaust gas material, so that the purpose of cutting metal is achieved. From here we can see that laser cutting is essentially different from traditional machining. The laser cutting machine generates a laser beam through the laser transmitter. This laser beam will enter the external circuit system and converge to form a high-density and high-intensity laser beam, and then directly irradiate the surface of the material. After the material is irradiated, its temperature rises rapidly until it reaches its peak. At this time, the material begins to vaporize to form holes, and then the laser beam begins to move on the surface of the material to form a cut.   Many industries are already using laser cutting technology, such as cutting metal materials, cutting textile materials, and using lasers for marking and engraving. But I believe many people still don't understand the specific working principle of metal laser cutting machine. The core of the application principle of    metal laser cutting machine is u0026mdash;u0026mdash; the use of laser beams. By converging the laser into a laser beam with a very small diameter, it can reach a very high, high-power and high-density heat source. The material is heated and vaporized by this high heat source, thereby evaporating and creating a small hole. Then the beam starts to move, and the beam moves and the material is released and then vaporized to reach the cutting purpose. At the same time, the material will not be deformed or damaged because of the small impact.   At the same time, in the process of cutting the material, the laser is used for cutting, and auxiliary gas matching the material is added. For example, when cutting steel, oxygen is added to chemically react with the hot gas generated by the metal to oxidize it and help blow away waste gas residues. Only compressed air is used when cutting plastic and other materials, and inert gas is added when cutting cloth and paper. The auxiliary gas can also cool the focusing lens and prevent the lens from overheating due to soot progress.  Most materials can be cut by laser. Therefore, laser cutting plays a very important role in industrial manufacturing. Most materials can be cut and deformed regardless of their hardness. However, it does not deny that some high emissivity materials will also make laser cutting very difficult or even impossible to cut because of their excellent thermal conductivity properties.   metal laser cutting machine is also loved by many electromechanical manufacturing industries because of its features of no burrs, no wrinkles, and high processing accuracy. Because of its precise micro-control operation, CNC laser cutting can cut materials of different shapes and sizes very conveniently.   Wuhan Gaoneng Laser Equipment Manufacturing Co., Ltd. is a high-tech enterprise integrating Ru0026D, production and sales of professional laser complete sets of equipment.
