Tips for cutting aluminum with fiber laser cutting machine

In recent years, the efficiency problem of metal processing has gradually been solved by fiber laser cutting machines, and common metals are mainly stainless steel, carbon steel, and aluminum plate. Until now, both stainless steel and carbon steel can be easily cut. As a high reflectivity material, cutting aluminum has always been a difficult problem for fiber laser cutting machines. High reflectivity materials have low absorption rates for lasers, and aluminum is the main circulating material in the market. This has forced us to think about how to use fiber laser cutting machines to cut aluminum.

1. If the subsequent appearance of the aluminum material is not considered, the surface of the aluminum material can be painted black, which can effectively reduce the reflectivity of the aluminum material to the laser, making it easier to cut the aluminum material.
2. If the economy allows, a larger laser can be replaced, and a slightly larger laser power can be selected according to the thickness to be cut, which can better cut aluminum materials.

3. Aluminum can be cut better by adjusting the cutting process. Aluminum itself cannot withstand high temperatures, and if the cutting dwell time is not appropriate, burrs will be generated. By adjusting parameters such as cutting focus, speed, output power, and air pressure, aluminum can be cut better.

4. Choosing the appropriate auxiliary gas, due to the special color of aluminum and to ensure uniform color of the cut product, nitrogen can effectively prevent oxidation and preserve the characteristics of the material itself. Therefore, using nitrogen is a better choice.

Overall, it is not difficult for laser cutting machines to cut aluminum materials. Many manufacturers on the market have developed cutting heads that resist high reflectivity materials, which can effectively reduce the damage of reflection to lenses. As long as the processing technology is patiently adjusted and the cutting speed is paid attention to, aluminum materials can be easily cut.
