In addition to stainless steel and carbon steel, copper and aluminum are also widely used in the metal processing industry. Due to the wide processing demand in this field, many customers who process gold sheets will ask whether the fiber laser cutting can cut aluminum, copper and other high reflective objects when purchasing the fiber laser cutting machine. In fact, a few years ago, optical fiber laser cutting machine can cut aluminum plates. After repeated attempts to innovate and cut high negative materials, the quality is getting higher and higher.
In fact, the laser processing of highly reflective materials is very important in the current manufacturing environment and market application, but many laser technologies have been affected to some extent due to their sensitivity to the reflected light. The unstable operation and destructive automatic shutdown phenomenon in the processing process even cause great damage to the laser, which virtually shortens the service life of the laser. For example, copper, aluminum and other alloys are difficult to be processed by laser cutting due to their own properties (high reflectivity), so special attention should be paid when using aluminum plate laser cutting machine.
In addition, in the processing process, because the aluminum material is not resistant to high temperature, it is easy to produce burrs when cutting the aluminum material, so 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 speed is also easy to produce burrs. Too slow cutting speed will lead to aluminum cracking and seriously affect the cutting quality.
