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. In the process of 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. Cutting thickness 3000W can cut aluminum below 8mm, 6000W can cut aluminum below 16mm, 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.

Laser cutting machine cutting aluminum plate also depends on the power of the laser generator. The maximum thickness of 6000W can be cut to 16mm, and the thickness of 4500W can be cut to 12mm, but the processing cost is only high, because it is a highly reflective material, and laser cutting uses The focused high-power-density laser beam irradiates the workpiece, so that the irradiated material rapidly melts, vaporizes, ablates or reaches the ignition point, and at the same time, the molten material is blown away by the high-speed airflow coaxial with the beam, thereby realizing the cutting of the workpiece.



Is the cut surface of laser cut aluminum sheet as smooth as cutting other materials?

The incision of the aluminum plate is also smooth. The aluminum plate is only a highly reflective material, which requires a large laser generator. The cutting gas, like other materials, is cut with nitrogen gas, which will not cause the surface to be uneven.



Aluminum plate using laser cutting features:

1. Thin cutting seam: The cutting seam of laser cutting aluminum plate is generally 0.1mm-0.2mm

2. The cutting surface is smooth: the cutting surface of the laser-cut aluminum plate has no burrs and no slag.

3. Small thermal deformation: The laser processing of laser processing has thin slits, high speed and concentrated energy, so the heat transmitted to the material to be cut is small, and the deformation of the material is also very small.

4. Material saving: laser processing adopts computer programming, laser equipment can cut different shapes of aluminum plate processing parts, improve the material utilization rate of aluminum plates, and save a lot of material costs.

5. The thickness of the aluminum plate that can be cut mainly depends on the power of the laser generator. Generally, the maximum thickness of 6000W can be cut to 16mm, and the thickness of 4500W can be cut to 12mm.
