Fiber laser cutting machine is an excellent cutting tool, which plays a very important role in the cutting of many materials. However, do you know that the quality and performance of materials also have a great impact on the cutting effect of fiber laser cutting machines?
1. Material surface reflectance of fiber laser cutting machine: For the 10.6mm far-infrared beam emitted by CO2 fiber laser cutting machine, non-metallic materials absorb it better, that is, it has a high absorption rate, while surface metal materials have an absorption rate of 10.6. The mm beam has poor absorption, especially for gold, silver, copper, and aluminum metals with high reflectivity. Generally, it is not suitable to cut with CO2 laser beams, especially continuous wave beams. For aluminum and copper metals, it usually takes more than 3KW to form sufficient starting power to obtain the initial small holes required for penetration effects. Ferrous materials such as iron and steel and nickel, titanium, etc. have a certain absorption rate for the 10.6mm CO2 beam, especially when the surface of the material is heated to a certain temperature or an oxide film, its absorption rate will be greatly improved, so as to obtain better cutting effect.
2. Surface condition of the material of the fiber laser cutting machine The surface condition of the material directly affects the absorption of the light beam, especially the surface roughness and the surface oxide layer will cause a significant change in the surface absorption rate. In laser cutting practice, the influence of the surface state of the material on the beam absorption rate can sometimes be used to improve the cutting performance of the material. When we use the fiber laser cutting machine, we also need to pay attention to the performance of the cutting material, so that the fiber laser cutting machine can play a better effect.
