The so-called laser cutting is the energy released when the laser beam is irradiated on the surface of the workpiece to melt and evaporate the workpiece to achieve the purpose of cutting and engraving. Features such as smoothness and low processing cost will gradually improve or replace traditional metal cutting process equipment. Laser cutting machine system generally consists of laser generator, (external) beam transmission components, workbench (machine tool), microcomputer numerical control cabinet, cooler and computer (hardware and software) and other parts.
1. Principle
The basic principle of laser cutting is: focus the laser on the material, heat the material locally until it exceeds the melting point, and then blow the molten metal away with coaxial high-pressure gas or the generated metal vapor pressure, as the beam moves relatively linearly with the material, Continue the holes to form very narrow slits.
2. Follow-up system
In the large-format laser cutting machine, the processing height of different places is slightly different, which causes the surface of the material to deviate from the focal length, so that the focused spot size and power density are different in different places, and the laser cutting quality of different cutting positions is very inconsistent. , can not meet the quality requirements of laser cutting.
3. Auxiliary gas
The auxiliary gas suitable for the material to be cut must be added during the cutting process. In addition to blowing away the slag in the slit, the coaxial gas can also cool the surface of the machined object, reduce the heat affected zone, cool the focusing lens, and prevent smoke and dust from entering the lens holder and contaminating the lens and causing the lens to overheat. The choice of gas pressure and type has a great influence on cutting. Common gases are: air, oxygen, nitrogen.
