What is the principle of the metal optical fiber laser marking machine? It is to use the laser beam to remove the metal materials in specific parts, so as to achieve the desired effect or logo. In the application of metal laser marking and carving, the laser beam is like a chisel used in carving, which chisels away the excess metal materials.
Metal laser marking is generally divided into two types: shallow carving and deep carving. Generally, the depth of shallow carving is 5~25, and the depth of deep carving is generally deep. The specific depth depends on different materials, the laser power used and the carving time.
Shallow engraving is mainly used for various tools of laser marking machine, permanent marking on the surface of spare parts, and deep engraving is mainly used for carving molds, seals, etc. Whether the required depth determines the power of the required fiber laser marking machine and the choice of lasers (some brands of lasers have certain advantages in depth).
Generally speaking, the marking depth is related to factors such as the laser absorption of the marked material, the laser power and the action time of the laser on the marked material. The depth marking usually requires a long action time. On the surface of various metal plastic materials, the optical fiber laser marking machine and the shallow carving can be carried out, such as marking identification code, company trademark and more complex images.
Compared with the traditional marking process, the modern laser marking has made a great breakthrough. What are the mainstream marking materials of laser marking.
1. The range of processing materials is more extensive. It can mark a variety of non-metallic and metallic materials, especially for brittle materials, high melting point materials, high hardness materials, etc. Traditional marking machines can only process certain specific non-metallic materials.
2. The laser technology is different from the old marking machine. Only the surface of the object to be processed can be processed and marked. With the integration and innovation of laser technology, laser marking can be completed only by concentrated high-energy laser irradiation on the surface of the object to be processed. This indirect contact processing will not damage the surface of the object to be processed, and there is no cutting force, The quality of characters is very high.
3. The laser beam gathered by the characteristics of high energy density of laser is very thin, making the influence range of processed objects very small, which is conducive to reducing the loss of raw materials.
