Processing often encounter aluminum plate processing, one of the problems is aluminum plate can be laser cutting?The answer is yes.
A few years ago, laser cutting machines were able to cut aluminum plates. At that time, workers took ink and painted on aluminum plates (it was said that the reflectance of aluminum plates was high, so they were afraid of reflecting the laser). In addition, laser parameters were not adjusted well.At that time, you could only cut aluminum sheets that were 1 mm thick.With experience, the aluminum cut is smooth and no slag.
Laser cutting aluminum plate also look at the power of laser generator, the most can cut to 16 mm thick 6000 w, 4500 w cut to 12 mm is done, but only the high cost of processing, because, this is a high reflective materials, laser cutting is the use of the focus of the high power density laser beam artifacts, cause the irradiation materials rapidly melting, evaporation and ablation or reach the ignition point, at the same time with the aid of high-speed airflow and beam coaxial blow molten material, so as to realize the workpiece cut open.
Is the laser-cut surface of aluminum as smooth as that of other materials?
The cut of aluminum plate is also smooth. Aluminum plate is only a highly reflective material, which requires a large laser generator. The cutting gas, like other materials, is cut with nitrogen, which will not cause the surface to be not smooth.
Laser cutting features of aluminum plate:
1. Fine cutting seam: The cutting seam of laser cutting aluminum plate is generally between 0.1mm and 0.2mm
2. Smooth cutting surface: The cutting surface of laser cutting aluminum plate is burr free and slag free.
3, small thermal deformation: laser processing of laser slit, fast speed, concentrated energy, so the heat transferred to the material to be cut is small, causing material deformation is also very small.
4, material saving: Laser processing adopts computer programming, laser equipment can be different shape of aluminum plate machining workpiece material nesting, improve the material utilization rate of aluminum plate, save a lot of material costs.
5. How thick aluminum plate can be cut mainly depends on the power of laser generator. Generally, the thickness of 6000W can be cut to 16mm, and that of 4500W to 12mm.
Conclusion: According to personal experience, the price of carbon dioxide laser machine is relatively low and the power of laser generator is large. You can try to cut aluminum plate when you are in special need.Notice, as I said above, that you coat the aluminum plate with black absorbent color to prevent reflective lenses or laser heads from burning.As for the fiber laser machine or do not cut the aluminum plate, it is not worth the loss, choose other ways to process the aluminum plate.
Precautions for laser cutting aluminum plate: aluminum plate belongs to high anti-material, which causes great damage to the laser and should be used as little as possible.It is recommended that the processing of aluminum plate below 6 mm can be used CNC punch processing, more than 6 mm water cutting processing.
