Aluminum plate processing is a common problem encountered in Sheet Metal Processing. One of the questions is whether aluminum plates can be laser cut? The answer is yes, it can be cut with laser.

A few years ago, laser cutting machines could already cut aluminum plates. I remember when the workers applied ink to the aluminum plate (it is said that the aluminum plate has a high reflection coefficient and is afraid of reflecting laser). In addition, laser parameters are not easy to adjust. At that time, only aluminum plates with a thickness of 1mm could be cut. After accumulating experience, aluminum plate cutting is very smooth and slag free.

The cutting of aluminum plates by a laser cutting machine also depends on the power of the laser generator. The thickness of 6000W can be cut to 16mm, and 4500W can be cut to 12mm. But the processing cost is high because it is a highly reflective material. Laser cutting is the use of a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, burn, or reach the ignition point. At the same time, with the help of a coaxial laser beam, high-speed airflow blows away the molten material, thereby achieving cutting of the workpiece.

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

The cutting edge of aluminum plate is also smooth. Aluminum plate is just a highly reflective material that requires a large laser generator and cutting gas. Like other materials, it is cut with nitrogen gas, which will not cause uneven surface.

The above are some personal experiences of aluminum laser cutting. Let's collect information from a professional perspective to explain.

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

2. Smooth cutting surface: The laser cut aluminum plate has no burrs or slag on the cutting surface.

3. Small thermal deformation: The laser cutting seam of laser processing is thin, fast, and energy concentrated, so the heat transferred to the cut material is small, and the deformation of the material is also very small.

4. Material saving: Laser processing uses computer programming, and laser equipment can cut materials for aluminum plate processing parts of different shapes, improving the material utilization rate of aluminum plates and saving a lot of material costs.

The thickness of cutting aluminum plates depends on the power of the laser generator. Generally speaking, a thick aluminum plate of 6000W can be cut to 16mm, and 4500W can be cut to 12mm.
