Difficulties and solutions of optical fiber cutting aluminum plate
Aluminum plate has always been one of the difficulties of laser cutting. As aluminum plate is a high-reflective material with low laser absorption rate, it is difficult to cut aluminum plate by laser. But because of its wide processing demand, we have to think about how to cut aluminum plate quickly and safely by laser. Laser equipment can be used for cutting high reflective materials such as copper plate and aluminum plate.
Laser cutting of aluminum plate can reduce the difficulty of cutting by some means, such as blackening the aluminum surface, which reduces the reflection degree of aluminum plate. Another reason for the difficulty of aluminum plate cutting is that the parameters of the laser machine are not easy to adjust. Compared with ordinary metal materials, the cutting process is difficult to grasp, and the cut is relatively rough and easy to hang slag.
In fact, there are many high-reflective materials like aluminum. Because the laser equipment is really sensitive to light, there is a risk of unstable operation and damage to the laser lens during the processing process. Generally, it is necessary to use a high-power laser. The processing process needs to be patiently adjusted. Pay attention that the speed should not be too fast to prevent burrs, and it should not be too slow, which may cause cracks near the cutting edge, It affects the cutting quality of aluminum plate.
In addition, it is recommended to use nitrogen when laser cutting aluminum panels, because of the special color of aluminum and to ensure uniform color of the cut products, nitrogen can effectively prevent oxidation and retain the characteristics of the material itself. Using nitrogen is a better choice. The cutting thickness of 2000w can be cut to 6-84000w, and the cutting thickness of 126000w can be cut to less than 16.
