What aspects should be paid attention to when cutting aluminum by laser cutting machine

Cutting aluminum has always been a cutting problem for fiber laser cutting machines, mainly because aluminum is a highly reflective material and has a low absorption rate for laser light. At the same time, aluminum is a widely used material in the market, which makes us have to think about how to To solve the problem of laser cutting aluminum, what aspects should be paid attention to in the process of cutting aluminum?

1. Paint the surface of the aluminum material black, which can effectively reduce the reflection degree of the aluminum plate, and then cut it;

2. During the processing, it is necessary to focus on the control process, because aluminum materials are not resistant to high temperature, and compared with ordinary metal materials, the cutting process is more difficult to grasp, and burrs are prone to occur in the process of cutting aluminum materials;



3. The laser cutting speed also needs to be controlled. Too fast cutting is also prone to burrs, and too slow cutting speed will cause cracks in the aluminum material, which will affect the cutting quality;

4. It is recommended to use nitrogen gas when cutting aluminum plate by aluminum laser cutting machine, because of the special color of aluminum and to ensure the uniform color of the cut product, nitrogen can well prevent oxidation and retain the characteristics of the material itself. It is better to use nitrogen. choose;

5. The cutting thickness of 3000W can cut aluminum below 8mm, 6000W can cut aluminum below 16mm, and 10000W can cut aluminum below 20mm.

In general, the fiber laser cutting machine can cut aluminum, and the processing technology should be adjusted patiently, and the cutting speed should be paid attention to. After reading the precautions for cutting these aluminum laser cutting machines, I believe everyone can use them correctly.
