Analysis of the Causes of Power Decline in Fiber Laser Cutting Machine

In the process of long-term use, the fiber laser cylinder machine has some more or less loss, such as slow cutting speed and poor cutting precision. Many people think that the laser power is reduced. There are many reasons that affect the power reduction of laser cutting machines, not necessarily the problem of lasers. The following is the reason why we analyze the power drop of the fiber laser cutting machine:

The first is the focus orientation, which affects the cutting accuracy, especially the focal spot diameter. The focal spot diameter should be as small as possible to produce a narrow slit; the focal spot diameter is proportional to the focal depth of the focusing lens, and the smaller the focal depth of the focusing lens, the smaller the focal spot diameter.

Secondly, the distance of the nozzle, the distance between the workpiece and the nozzle also affects the power reduction of the fiber laser cutting power. If the distance is too far, it will cause unnecessary kinetic energy. If the distance is too close, it will affect the dispersing ability of the spattered and cut products. The suitable distance is 0.8mm. In addition, the fiber laser cutting and cutting machine is mainly used to cut the surface of the workpiece. Followed by the conditioning, the height of the nozzle and the workpiece must be consistent throughout the operation.

Again, the cutting speed, the cutting speed has a great influence on the power of the fiber laser cutting, and the cutting speed is proportional to the power of the fiber laser cutting. The quality of the cut together is related to the quality of the laser beam. It is also related to the characteristics of the laser beam aggregation system, that is, the size of the laser beam after aggregation has a great influence on the quality of the laser cut.

Then there is the auxiliary gas. The size of the auxiliary gas and gas pressure also affects the power of the laser laser cutting. The auxiliary gas is preferably compressed air or inert gas. If the thickness of the processed material is added, the gas pressure should be appropriately lowered when the cutting speed is slow, and the lower gas pressure can be used to prevent the edge from being frosted.

Finally, the laser power, if the first four items have been removed, it is considered that the laser power is reduced. Any piece of equipment will exhibit some parts aging after long-term use. The laser is the most central and most important component of fiber laser cutting, and it will also show a power drop after long-term use. In addition to the above points, the performance, size and thickness of the processed materials will also affect the power reduction of the fiber laser cutting start-up.
