With the wide application of high-power laser cutting machines, more and more types of materials are being cut. I believe that everyone has encountered similar problems in this process. Some special materials are difficult to cut, such as brass and other high-reflective materials. material, which cannot meet the high-quality cutting requirements. How to do it? Let’s take a look at several common material cutting skills summarized by professional laser cutting machine manufacturers!
Laser cutting skills of aluminum, copper and brass for laser cutting machines:
Aluminum is a material with high reflectivity and good thermal conductivity among metal materials. Due to the reflection problem of laser irradiation on aluminum material, the laser cutting effect is reduced, and severe cutting cannot be performed. Undoubtedly, in order to cut better, the reflection problem must be solved, and the anti-reflection device can be used to solve the problem of cutting aluminum reflection. The power of the equipment is different, and the thickness of the aluminum that can be cut is different. The best gas for cutting aluminum is nitrogen, so that the surface of the finished product is smooth and burr-free. Copper, like aluminum, is also a high-reflection material. It also needs an anti-reflection device and needs to be cut with nitrogen, but the difference is that copper with a thickness of less than 2mm should be cut with oxygen, and brass with a thickness of less than 1mm should be cut with nitrogen.
Laser cutting skills of carbon steel for laser cutting machine:
Carbon steel is a material with relatively low reflectivity. When cutting carbon steel, oxygen cutting should be used. Using oxygen cutting can greatly improve the cutting efficiency. The oxide film produced during the cutting process can increase the beam spectral absorption factor of the reflective material. The only downside is slight oxidation on the cut edges. If the quality of the cut surface is high, it is recommended to use nitrogen for high-pressure cutting.
Fiber laser cutting machine stainless steel laser cutting skills:
Nitrogen gas is generally used for stainless steel plate cutting, and the cutting edge is free of burrs. Due to the characteristics of stainless steel itself, it can speed up the flow of liquid, making the cutting speed faster and the surface smoother. If it is cut with oxygen, it will have the same problem as carbon steel cutting. Oxidation will cause the cut surface to turn black and have burrs.
