What should I do if the efficiency of the laser cutting machine decreases?

　　The fiber laser cutting machine has been rapidly occupying the market with high efficiency and high precision, but many people have found that this is not the case after purchasing the fiber laser cutting machine and returning to actual use. The efficiency of the fiber laser cutting machine was reduced for no reason. They didn't know it, and the reason was a headache. We invited a professional technician to see how he responded to the reduced efficiency of the fiber laser cutting machine.

　　What should I do if the efficiency of the fiber laser cutting machine decreases?

　　 First of all, the focus position of the fiber laser cutting machine, which affects the accuracy of cutting, especially the diameter of the focus . The diameter of the focal point should be as small as possible to produce a narrow slit; the diameter of the focal point is proportional to the focal depth of the focusing lens. The smaller the focal depth of the focusing lens, the smaller the focal diameter.

　　 The second is the distance between the nozzles of the fiber laser cutting machine. The distance between the workpiece and the nozzle will also affect the power drop of the fiber laser cutting machine. Too far will cause unnecessary waste of kinetic energy, and too short will affect the dispersion ability of splash cutting products, 0.8mm is appropriate. In addition, the fiber laser cutting machine cuts the workpiece with uneven surface mainly for tracking. To achieve this goal, the height of the nozzle and the workpiece must always be the same during the operation.

　　 The third is the cutting speed of the fiber laser cutting machine. The cutting speed has a great influence on the power of the fiber laser cutting machine. 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, as well as the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the cutting quality.

　　 Then there is the auxiliary gas of the fiber laser cutting machine. The size and pressure of the auxiliary gas will also affect the power of the fiber laser cutting machine. The auxiliary gas is best to use compressed air or inert gas. If the thickness of the processed material increases or the cutting speed is slow, the gas pressure must be appropriately reduced. Cutting with lower gas pressure can prevent the cutting edge from freezing.

　　The last item is the laser power of the fiber laser cutting machine. If the first 4 items are removed, the laser power is considered lower. After long-term use of any equipment, some parts will deteriorate. The laser is the core and most important part of the fiber laser cutting machine, and the power will decrease if it is used for a long time. In addition to the above points, the performance, size and thickness of the processed material will also affect the power drop of the fiber laser cutting machine.

　　 The above is the specific content of what should be done when the efficiency of the fiber laser cutting machine decreases. It can be seen that there are many factors that affect the efficiency and accuracy of the fiber laser cutting machine. When we meet the efficiency of the fiber laser cutting machine, we must return it to the manufacturer for inspection and maintenance. Only in this way can the processed products meet customer requirements.
