As long as the machine will have a loss of days, the fiber laser cutting machine is also unavoidable, in the process of long-term use, there will be a slow cutting speed, cutting accuracy and other problems. Many people think that the laser power of the laser cutting equipment must have decreased, in fact, it is not correct, there are many reasons that will affect the power of the laser cutting machine, not necessarily the laser problem.

Focus site

The focusing position will affect the precision of laser cutting, especially in the focus spot diameter. The focal spot diameter should be as small as possible to create a narrow slit; The focal spot diameter is proportional to the focal depth of the focal lens, and the smaller the focal depth of the focal lens, the smaller the focal spot diameter.

The distance between the nozzle and the workpiece

The distance between the nozzle and the workpiece also affects the power reduction of the fiber laser cutting machine. Too far will cause unnecessary waste of kinetic energy, too close will affect the dispersion of the splash cutting product, the appropriate distance is 0.8 mm. In addition, the fiber laser cutting machine mainly realizes the cutting of the workpiece with uneven surface through subsequent adjustment, and the height of the nozzle and the workpiece should always be consistent during operation.

Cut-off speed

The cutting speed has a great impact on the power of fiber laser cutting equipment, 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 also related to the characteristics of the laser beam concentrating system, that is, the size of the laser beam after concentrating has a great impact on the laser cutting quality.

Auxiliary gas

The size and pressure of the auxiliary gas also affect 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 air pressure should be properly reduced, and the cutting edge can be prevented from frosting with a lower air pressure.

Laser power

If the previous several items are excluded, the laser power reduction is considered. After a long period of use, some parts of any equipment will age. The laser is the core and most important component of the metal laser cutting machine, and the power will decrease after long-term use. In addition to the above points, the performance, size and thickness of the processed material will also affect the power reduction of the fiber laser cutting machine.
