Reasons for the Power Drop of Laser Cutting Machine

Reasons for the power drop of laser cutting machine
Generally, the normal life of a laser cutting machine is about 5 years, so the power of long-term use will definitely be reduced.
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 a distance will result in unnecessary waste of kinetic energy, and too close a distance will affect the spreading ability of the splash cut product. A suitable distance is 0.8 mm. In addition, the fiber laser cutting machine can mainly cut the workpiece with uneven surface by 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 the cutting 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 influence on the laser quality.
4. Auxiliary gas, auxiliary gas and gas pressure will also affect the power of the fiber laser cutting machine. Compressed air or nitrogen is recommended as auxiliary gas. If the thickness of the material increases or the cutting speed is slow, the air pressure should be appropriately reduced. Use a low pressure cut to prevent frosting on the edge cut.
