Reasons for the decline in power of fiber laser cutting machines
Fiber laser cutting machines have some more or less losses in the long-term use process, such as slow cutting speed and poor cutting accuracy. Many people think that the laser power is reduced. There are many reasons that affect the power reduction of laser cutting machines, not necessarily the problem of lasers. The work laser helps everyone analyze the reasons for the power drop of the fiber laser cutting machine:
The first is the focus position, which affects the cutting accuracy, especially the focus spot diameter. The focal spot diameter should be as small as possible to produce a narrow slit; the focal spot diameter is proportional to the focal depth of the focusing lens, and the smaller the focal depth of the focusing lens, the smaller the focal spot diameter.
Followed by the distance of the nozzle, the distance between the workpiece and the nozzle also affects the power drop of the fiber laser cutting machine. If the distance is too far, it will cause unnecessary waste of kinetic energy. If the distance is too close, it will affect the dispersing ability of the spattered cutting products. The suitable distance is 0.8mm. In addition, the fiber laser cutting machine cuts the surface of the workpiece by the follow-up adjustment. To achieve, the height of the nozzle and the workpiece must be consistent throughout the operation.
Again, the cutting speed, the cutting speed has a great influence on the power of the fiber laser cutting machine, and the cutting speed is proportional to the power of the fiber laser cutting machine. At the same time, the cutting quality is related to the quality of the laser beam. In addition, it is related to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the laser cutting quality.
