Laser cutting machines have been used in all walks of life, so what is the principle of laser cutting machines? The laser cutting machine supplier below will give you an answer.
The laser is actually a kind of light. Like other light in nature, it is produced by the transition of atoms (molecules or ions) and is caused by spontaneous radiation. Although the laser is light, it is obviously different from ordinary light in that the laser only relies on spontaneous emission for a very short period of time, and the subsequent process is completely determined by the excitation radiation. Therefore, the laser has a very pure color and almost no divergence. It also has extremely high luminous intensity. This makes the laser power very concentrated, and only a small amount of heat is transferred to other parts of the metal sheet during metal cutting, resulting in little or no deformation. The use of a laser can cut blanks of complex shapes very accurately, and the cut surface of the cut blanks is smooth, almost no further processing is necessary. This is one of the reasons why the laser cutting machine has developed rapidly.
The laser also has high brightness, high coherence, high intensity, and high directivity. After the laser is generated by the laser, it is transmitted by the reflecting mirror and irradiated on the processed item through the focusing mirror, so that the processed item (surface) is subject to strong heat and temperature The sharp increase will cause the point to melt or vaporize rapidly due to high temperature, and match the movement track of the laser head to achieve the purpose of processing. According to different work 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.
A brief overview of the principle of the laser cutting machine in one sentence is: laser cutting is the energy released when the laser beam is irradiated to the surface of the workpiece to melt and evaporate the workpiece to achieve the purpose of cutting, engraving or welding.
