Laser cutting machine has been applied to all walks of life, so what is the principle of laser cutting machine? The following will give you an answer.
In fact, laser is also a kind of light. Like other light in nature, it is generated by the transition of atoms (molecules or ions) and is caused by spontaneous radiation. Although laser is light, it is different from ordinary light in that laser only depends on spontaneous radiation for a very short time at the beginning, and the subsequent process is completely determined by stimulated radiation. Therefore, laser has very pure color, almost no divergence, and has extremely high luminous intensity. This makes the laser power very concentrated. When metal cutting, only a small amount of heat is transferred to other parts of the metal plate, resulting in little or no deformation. The blanks with complex shapes can be cut very accurately by using laser, and the cut faces of the blanks are smooth, so it is almost unnecessary to make further treatment. This is also a reason for the rapid development of laser cutting machines.
At the same time, the laser also has high brightness, high coherence, high intensity, and high directivity. After being generated by the laser, the laser is transmitted by the reflector and shines on the processed articles through the collecting mirror, so that the processed articles (surfaces) are subject to strong thermal energy and the temperature increases dramatically, so that the point can be rapidly melted or vaporized due to high temperature. The purpose of processing can be achieved by matching the running track of the laser head. According to the different ways of working clothes, laser equipment can be divided into:;
As a high-tech laser cutting technology, since its inception, it has been developing laser products suitable for various industries according to different social needs, such as laser cutting machines, laser engraving machines, laser marking machines, laser welding machines and other products. Although the domestic laser industry started late and lagged behind some developed countries in technology research and development, with the rapid development of domestic industry, In the R&D and production of the complete machine and some spare parts, it has gradually moved closer to foreign advanced products. In some aspects, it is even better than foreign products, and with the advantage of price, it has occupied a dominant position in the domestic market; Moreover, many manufacturers have gone abroad to the world. Whether a laser cutting machine manufacturer has its own foreign trade channels is also a reflection of the strength of this enterprise.
In a word, the principle of laser cutting machine is: laser cutting is to melt and evaporate the workpiece by the energy released when the laser beam shines on the workpiece surface, so as to achieve the purpose of cutting, carving or welding.
