At present, in the metal processing industry, in addition to stainless steel and carbon steel, the utilization rate of copper and aluminum is relatively high. Because the processing demand in this field is relatively wide, many customers who do sheet metal processing will ask whether fiber laser cutting can cut aluminum, copper and other high-reflective materials when they buy fiber laser cutting machines. In fact, a few years ago, the fiber laser cutting machine was able to cut aluminum plates. After repeated attempts to innovate, the quality of cutting high-reflection materials is getting higher and higher.
Actually, everyone knows that the laser processing of high-reflection 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 the return light, resulting in Unstable operation and destructive automatic shutdown occurred during processing, and even caused great damage to the laser, which invisibly shortened the life of the laser. For example, copper, aluminum and its alloys, due to their own characteristics (high reflectivity), make laser cutting difficult to process. Among them, special attention should be paid when using aluminum plate laser cutting machines.
In addition, during the processing process, because the aluminum material is not resistant to high temperatures, burrs are prone to appear in the process of cutting the aluminum material. It is necessary to focus on the control process to obtain the ideal cutting quality. The cutting speed also needs to be controlled, too fast cutting is also prone to burrs, too slow cutting speed will cause cracks in the aluminum material, which will affect the cutting quality.
