Generally, the normal life of laser cutting machine is about 5 years, so the power will definitely decrease after a long time of use. Now, let's summarize the reasons for the decrease of laser cutting machine power:

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 optical fiber laser cutting machine. Too long distance will lead to unnecessary waste of kinetic energy, and too close distance will affect the diffusion ability of spatter cutting products. The appropriate distance is 0.8 mm. In addition, the optical fiber laser cutting machine can cut workpieces with uneven surfaces through the following adjustments, and the height of the nozzle and workpieces should always be the same during operation.

3. The cutting speed has a great influence on the power of the optical fiber laser cutting machine, and the cutting speed is proportional to the power of the optical fiber laser cutting machine. At the same time, the cutting quality is related to the quality of the laser beam and the characteristics of the laser beam focusing system. That is, the size of the focused laser beam has a great impact on the laser quality.

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

If the first four items are excluded, consider reducing the laser power. Long term use of any equipment will cause partial aging. Laser is the core component of optical fiber laser cutting machine. In addition to the above, the performance, size and thickness of processing materials will also affect the optical fiber laser cutting machine
