The normal life of the general laser cutting machine is about 5 years, so the use of power for a long time will certainly reduce. Now give you a summary of the reasons for the decline in the power of the laser cutting machine:

1. The focusing position will affect the cutting accuracy, especially the focusing diameter. The focus diameter should be as small as possible to form a narrow slit, and the focus diameter is proportional to the focus depth of the focusing lens, and the smaller the focus depth, the smaller the focus diameter.

2. The distance between the nozzles and the distance between the workpiece and the nozzle will also affect the power of the fiber laser cutting machine. Too long a distance will lead to unnecessary waste of kinetic energy, and too close a distance will affect the diffusion ability of the splash cutting product. The appropriate distance is 0.8 mm. In addition, the fiber laser cutting machine can mainly cut the workpiece with an uneven surface through the following adjustment, and the height of the nozzle and the workpiece should always be the same during the operation.

3. 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 quality of cutting is related to the quality of the laser beam, and also related to the characteristics of the laser beam focusing system. That is, the size of the focused laser beam has a great influence on the quality of the laser.

4 Auxiliary gas, auxiliary gas and gas pressure will also affect the power of the fiber laser cutting machine. It is recommended to use compressed air or nitrogen as an auxiliary gas. If the thickness of the material increases or the cutting speed is slow, the air pressure should be appropriately reduced. Use low pressure cuts to prevent frosting on edge cuts.

If you exclude the first four items, you need to consider reducing the laser power. Long-term use of any equipment will occur partial aging. Laser is the core component of fiber laser cutting machine. In addition to the above, the performance, size and thickness of the processed material will also affect the power of the fiber laser cutting machine.
