What is the reason for the decrease in power of laser cutting machines

If it is a machine, there will be losses, and the same goes for metal material laser cutting machines. In the long-term development and use process, we will definitely affect the existence of some more or less losses, such as slow cutting speed, poor cutting accuracy, and so on. Many people can think that it must be a decrease in laser power. In fact, there are many reasons that affect the decrease in laser cutting machine power, not necessarily laser problems. The following analyzes the reasons for the power failure of the fiber laser cutting machine:

Firstly, it is a focal point position that affects the cutting accuracy, especially the diameter of the social focal spot. The diameter of the focal spot is directly proportional to the depth of focus of the focusing lens. The smaller the depth of focus of the focusing lens, the smaller the diameter of the focal spot.

Secondly, the distance between the nozzle and the workpiece also affects the power capability of the fiber optic laser cutting machine. Being too far away can cause unnecessary waste of kinetic energy, while being too close can affect the dispersion of splashed cutting products. The appropriate distance is 0.8mm. Another fiber optic laser cutting machine mainly relies on its follow-up adjustment to achieve the cutting of uneven surface machined parts. During the operation and management process, the height between the nozzle and the machined part is not basically consistent.

Thirdly, cutting speed and cutting speed have a significant impact on the power of fiber laser cutting machines, and the cutting speed is directly proportional to the power of the fiber laser cutting machine. The quality of cutting work is related to the management of laser beam quality, as well as the characteristics of the laser beam focusing information system, that is, the size of the laser beam after focusing has a significant impact on the development of laser cutting quality.

There is also the size of the auxiliary gas, the auxiliary gas and gas pressure, and it is preferred to use compressed air or inert gas, which also affects the power of the fiber laser cutting machine. If the thickness of the processed material can be increased, or if the cutting speed develops slowly, the gas pressure should be appropriately reduced. Using gas pressure cutting with lower efficiency can prevent edge frosting.

Finally, if the first four have been excluded, it is considered a decrease in laser power. Any device that is used for a long time can lead to problems and aging of some components. Laser is the core and most important component of metal laser cutting machines, and long-term use can lead to a decrease in power. In addition to the above points, the performance, size, and thickness of processing technology materials can also affect the power capability of fiber laser cutting machines.
