In the long-term use of laser cutting machines, there are issues such as slow cutting speed and low cutting precision, and many people believe that the laser power has decreased. There are many reasons that can affect the power of laser cutting machines, not necessarily the laser itself. Zhou Xiang Laser can help analyze the reasons for the decrease in laser cutting machine power.

Position of the focus
It will affect the cutting precision, especially the spot diameter. The spot diameter should be as small as possible to form a narrower gap, and the spot diameter is proportional to the focal depth of the focusing lens. The smaller the focal depth of the focusing lens, the smaller the spot diameter.
Distance of the nozzle
The distance between the workpiece and the nozzle also affects the decrease in the power of the laser cutting machine. If the distance is too far, it will cause unnecessary kinetic energy waste, and if it is too close, it will affect the dispersion ability of the splattered cutting products. The appropriate distance is 0.8mm. In addition, the laser cutting machine mainly relies on its follow-up adjustment to achieve cutting on uneven workpiece surfaces, and during operation, the height of the nozzle and the workpiece must always remain consistent.
Cutting speed
The cutting speed has a significant impact on the power of the laser cutting machine. At the same time, the cutting quality is related to the quality of the laser beam and also to the characteristics of the laser beam focusing system, that is, the size after the laser beam is focused has a great impact on the quality of laser cutting.
Auxiliary gas
The size of the auxiliary gas and the pressure of the gas also affect the power of the fiber laser cutting machine. The auxiliary gas uses compressed air or inert gas. If the material thickness increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Using low-pressure cutting prevents edge frosting.
If the first four items are excluded, consider reducing the laser power. Any equipment will show local aging after long-term use. The laser is the core component of the laser cutting machine. In addition to the above points, the performance, size, and thickness of the processed materials will also affect the decrease in the power of the laser cutting machine.
