Aluminum plate processing is often encountered in gold processing. One of the questions is whether the aluminium plate can be cut by laser. The answer is yes.
A few years ago, laser cutting machines could cut aluminium plates. When workers took ink on the aluminium plates (said to be because of the high reflection coefficient of the aluminium plates, afraid of reflecting laser), it was difficult to adjust the parameters of the laser. At that time, only 1 mm thick aluminium plate could be cut. Through the accumulation of experience, the incision of aluminum plate is very smooth and there is no slag hanging.

激光切割铝板也看看激光发生器的力量,较能降低到16毫米厚6000 w, 4500 w减少到12毫米,但只有处理费用高,因为,这是一个高反光材料,激光切割是利用高功率密度激光的焦点工件,使辐照材料迅速融化,蒸发和消融或达到燃点,同时借助高速气流和束流同轴吹塑材料，从而实现工件的开槽。
Laser cutting of aluminium sheet can also see the power of laser generator, which can be reduced to 16 millimeter thick 6000 w, 4500 w to 12 millimeter, but only the processing cost is high, because this is a high reflective material. Laser cutting is to use high power density laser focus workpiece, so that the irradiated material quickly melts, evaporates and melts or reaches the ignition point, at the same time, with the help of. High-speed airflow and beam coaxial blow moulding material, thereby realizing the grooving of the workpiece.

Is the cutting surface of laser cutting aluminium plate as smooth as other materials?
The cutting of aluminium sheet is very smooth. Aluminum sheet is only a kind of high reflective material, which requires a large laser generator. Cutting gas, like other materials, is cut with nitrogen, which will not make the surface not smooth.
The characteristics of laser cutting for aluminium sheet are as follows:
1. Fine Cutting Seam: Laser Cutting Aluminum Plate Cutting Seam is generally 0.1mm-0.2mm
2. Smooth cutting surface: laser cutting aluminum plate cutting surface without burrs and slag.
3. Small thermal deformation: the laser cutting slit is thin, fast and energy is concentrated, so the heat transferred to the cutting material is small, and the deformation caused by the material is very small.
4. Save material: Laser processing is programmed by computer. Laser equipment can cut different shapes of aluminium sheet workpieces, improve the utilization rate of aluminium sheet materials and save a lot of material costs.
5. 铝板的切割厚度主要取决于激光发生器的功率大小。一般较大厚度6000W可以切割到16mm, 4500W可以切割到12mm。
5. The cutting thickness of aluminium plate mainly depends on the power of laser generator. Generally, the maximum thickness of 6000W can be cut to 16 mm, and 4500W can be cut to 12 mm.
Aluminum plate belongs to high reflection material, laser damage is very big!
Generally, customers are not advised to use optical fiber laser cutting machine to cut aluminum plate, as little as possible!
A laser beam is hundreds of thousands of dollars, the damage is not worth it!
Conclusion: according to my experience, the price of CO2 laser is relatively low and the power of laser generator is relatively high. Note that, as I said above, a layer of absorbed light black on the aluminium plate prevents the reflected light from burning the lens or laser head. As for fiber laser or non-cutting aluminium sheet, it is not worth losing. We choose other ways to process aluminium sheet.
Cautions for laser cutting of aluminium sheet: aluminium sheet belongs to high reflective material, which will cause great damage to laser, so it should be used as little as possible. It is suggested that the aluminium sheet less than 6 mm be processed by numerical control punching machine and the aluminium sheet more than 6 mm be processed by water cutting.
