For the laser cutting equipment, it is inevitable that there are some more or less losses in the process of long-term use of the optical fiber laser cutting machine, such as slow cutting speed, poor cutting accuracy and other problems. In fact, there are many reasons that affect the power reduction of the laser cutting machine. Today, Redsail Laser will give you an inventory!
1、 Focus position. The focus position affects the cutting accuracy, especially the focus spot diameter. The focal spot diameter should be as small as possible to produce a narrow slit. Ourui Laser reminds us that the focal spot diameter is proportional to the focal depth of the focusing lens. The smaller the focal depth of the focusing lens is, the smaller the focal spot diameter is.
2、 Distance of the nozzle. The distance between the workpiece and the nozzle also affects the power reduction of the optical fiber laser cutting machine. Too far away will cause unnecessary waste of kinetic energy, and too close away will affect the dispersion ability of sputtered cutting products. The appropriate distance is 0.8mm. Ourui Laser reminds you that the optical fiber laser cutting machine mainly relies on its follow-up adjustment to cut workpieces with uneven surfaces, and the height of the nozzle and the workpieces should always be consistent during operation.
3、 Cutting speed. The cutting speed 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 laser beam quality, and also to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great impact on the laser cutting quality.
4、 Auxiliary gas. The size of auxiliary gas and gas pressure also affects the power of optical fiber laser cutting machine. Compressed air or inert gas is used as auxiliary gas. Ourui Laser reminds you that if the material thickness increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Cutting with lower gas pressure can prevent the edge from frosting.
If the first four items have been eliminated, finally check whether the laser power decreases. The laser is the core part of a fiber laser cutting machine, so the external optical path of the laser generator needs regular maintenance. In fact, after the laser of the laser cutting machine works for a period of time, it is inevitable that the power will drop. When the power drops to affect the production, the laser and the external optical path should be maintained. When the maintenance is completed, the cutting capacity can be restored to the factory level.
In addition, the performance, size and thickness of the materials processed by the laser cutting machine will also affect the power reduction of the optical fiber laser cutting machine. Ourui Laser reminds you that in the use of optical fiber laser cutting machine, we should pay more attention to our daily maintenance, fully understand the reasons for the attenuation of optical fiber laser cutting machine, and take corresponding measures to extend the service life of optical fiber laser cutting machine.
