The laser system of the fiber laser cutting machine needs regular maintenance
The carbon dioxide laser cutting system of the fiber laser cutting machine requires carbon dioxide as the laser gas. Due to the purity of carbon dioxide gas, the resonant cavity will be polluted and needs to be cleaned regularly. For a multi-kilowatt carbon dioxide system, this project costs at least US$20,000 per year. In addition, many carbon dioxide cutting requires high-speed axial turbines to deliver laser gas, and the turbines require maintenance and overhaul. Finally, compared with carbon dioxide cutting systems, fiber cutting solutions are more compact and have less impact on the earth, so less cooling is required and energy consumption is significantly reduced. There are also maintenance issues. The carbon dioxide gas laser system requires regular maintenance; the combination of less maintenance and higher energy efficiency makes fiber laser cutting and carbon dioxide laser cutting systems emit less carbon dioxide and is more environmentally friendly. Laser is a kind of light, and it emits light in nature. Like the body, it is produced by the transition of atoms (molecules or ions, etc.) and is caused by spontaneous radiation.
Although the laser of the fiber laser cutting machine is light, it is obviously different from ordinary light in that the laser only relies on spontaneous radiation in the first very short time, and the subsequent process is completely determined by the excitation radiation, so the laser has Very pure color, almost no divergent directionality, extremely high luminous intensity. The laser also has 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 object through the focusing mirror, so that the processed object (surface) is subjected to strong heat and the temperature increases sharply. The point is quickly melted or vaporized due to high temperature, and the operation track of the laser head is matched to achieve the purpose of processing. The application of laser processing technology in the advertising industry is mainly divided into two working methods: laser cutting and laser engraving. For each working method, we have some differences in the operation process.
