laser engraver for metal processing has the following advantages:
1. The thermal impact is very low. Compared with the traditional welding and cutting methods, laser processing does not need to generate high temperature, thereby minimizing the material damage to the base metal and coating;
2. The material deformation is very small, and a large amount of material deformation can be controlled within the range of a few percent of millimeters;
3. High-speed processing, for thin stainless steel materials, the welding speed can reach 10-20m/min, and there will be changes in response to different materials and thicknesses;
4. The surface of the processed material will be very clean and smooth. Most of the steel, aluminum and alloy materials will not have obvious deformation or damage on the surface after laser processing, and the appearance and characteristics of the original materials are maintained to the greatest extent;
5. Single-side processing without contact, because the working principle of the laser is non-contact beam focusing, so only one side needs to act on the material at a certain distance;
