Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as a light source. What is the reason for the decrease in efficiency that we find when using it? How should we solve it? Here we take a look!

1. The focus position of the fiber laser cutting machine, the focus position affects the cutting accuracy, especially the focus spot diameter. The diameter of the focal spot must be as small as possible to produce a narrow slit; the diameter of the focal spot 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.

The second is the distance of the nozzle of the fiber laser cutting machine. The distance between the workpiece and the nozzle also affects the power drop of the fiber laser cutting machine. Too far away will cause unnecessary waste of kinetic energy. If the distance is too close, it will affect the dispersing ability of the sputtered cutting product. The appropriate distance is 0.8mm. In addition, the fiber laser cutting machine mainly relies on its follow-up adjustment for cutting workpieces with uneven surfaces. To achieve, the height of the nozzle and the workpiece should always be consistent during operation.


2. The cutting speed of the fiber laser cutting machine 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 it is also related to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the laser cutting quality.

Then there is the auxiliary gas of the fiber laser cutting machine. The size of the auxiliary gas and gas pressure also affects the power of the fiber laser cutting machine. The auxiliary gas is preferably compressed air or inert gas. If the thickness of the processed material increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Using a lower gas pressure for cutting can prevent the cutting edge from frosting.

3. For the laser power of the fiber laser cutting machine, if the first 4 items have been excluded, it is considered that the laser power has dropped. After a long time of use of any equipment, some parts will appear aging phenomenon. The laser is the core and most important part of the fiber laser cutting machine, and its power will drop after long-term use. In addition to the above points, the performance, size and thickness of the processing material will also affect the power drop of the fiber laser cutting machine.
