Reasons for power drop of laser cutting machine?

Power drop of laser cutting machine

Generally, the normal life of a laser cutting machine is about 5-10 years, so the power will definitely be reduced when used for a long time. Now I will summarize the reasons for power drop of the laser cutting machine:
1. The focus position will affect the cutting accuracy, especially the focus diameter. The focal diameter should be as small as possible to form a narrow slit, and the focal diameter is proportional to the focal depth of the focusing lens, and the smaller the focal depth, the smaller the focal 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 distance will lead to unnecessary waste of kinetic energy, and too close distance will affect the spreading ability of splash cutting products. The appropriate distance is 0.8 mm. In addition, the fiber laser cutting machine can cut workpieces with uneven surfaces through the following adjustments, 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 directly 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 laser quality.
4. Auxiliary gas, auxiliary gas and gas pressure will also affect the power of 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 appropriately reduced. Use low pressure cutting to prevent frosting on the edge cutting.
If you exclude the first four items, you need to consider reducing the laser power. Partial aging will occur if any equipment is used for a long time. 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 fiber laser cutting machine.
