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

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

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

Second, the distance between the optical fiber laser cutting machine nozzles. The distance between the workpiece and the nozzle will also affect the power reduction of the optical fiber laser cutting machine. Too far will cause unnecessary waste of kinetic energy, and too short will affect the dispersion capacity of splash cutting products. 0.8mm is appropriate. In addition, the optical fiber laser cutting machine is mainly used to cut workpieces with uneven surfaces for tracking. To achieve this goal, the height of the nozzle and the workpieces must always be the same during operation.

The third is the cutting speed of the optical 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 and the characteristics of the laser beam focusing system, that is, the size of the focused laser beam has a great impact on the cutting quality.

Then it is the auxiliary gas of the optical fiber laser cutting machine. The size and pressure of the auxiliary gas will also affect the power of the fiber laser cutter. It is better to use compressed air or inert gas as auxiliary 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 four items are removed, the laser power is considered to be reduced. After any equipment is used for a long time, some parts will deteriorate. The laser is the core and the most important part of the fiber laser cutting machine. The power will drop after a long time of use. 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 cutter.

The above is the specific content of what to do when the efficiency of the optical fiber laser cutting machine decreases. It can be seen that there are many factors that affect the efficiency and accuracy of the optical fiber laser cutting machine. When we meet the efficiency of the optical 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.
