Because of the wide processing demand, many customers who do sheet metal processing will ask whether the optical fiber laser cutting can cut aluminum, copper and other high-reflective materials when purchasing the optical fiber laser cutting machine. Many salesmen of the optical fiber laser cutting machine manufacturers will tell the customers that they can cut. So is it really possible to cut? The answer is yes. Of course, aluminum and copper can be processed by laser cutting machine.

In fact, several years ago, the optical fiber laser cutting machine could cut the aluminum plate. I still remember that at that time, the workers painted ink on the aluminum plate (it is said that the aluminum plate has a high reflective coefficient and is afraid of reflecting the laser) and then cut it. In addition, the laser parameters are very difficult to adjust, because the process problem was that only 1mm thick aluminum plate could be cut. After accumulating experience, the cut of aluminum plate is also smooth and free of slag.

In fact, we all know that laser processing of highly reflective materials is very important in the current manufacturing environment and market applications. However, many types of laser technologies are affected by their inherent sensitivity to return light, resulting in unstable operation and destructive automatic shutdown during the processing process, and even causing great damage to the laser, which virtually shortens the life of the laser.

For example, copper, aluminum and their alloys, due to their own characteristics (high reflectivity), laser cutting is not easy to process, among which, special attention should be paid when using aluminum plate laser cutting machine.

In addition, because the aluminum material is not resistant to high temperature, burr is easy to appear in the process of cutting aluminum material, so it is necessary to focus on controlling the process to obtain ideal cutting quality. The cutting speed also needs to be controlled. Too fast cutting is also easy to produce burrs. Too slow cutting speed will cause cracks in aluminum materials, which will affect the cutting quality.
