What are the reasons that cause the power of the laser cutting machine to drop?

1.The focus position will affect the cutting accuracy, especially the focus 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 work piece 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 spattered cutting product. The appropriate distance is 0.8 mm. In addition, the fiber laser cutting machine can mainly cut work pieces with uneven surfaces through the following adjustments, and the height of the nozzle and the work piece should always be the same during 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 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 influence on the laser quality.


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 auxiliary gas.If the thickness of the material increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Use low pressure cutting to prevent frosting on the edge cutting.
