Firstly, the focus position of the fiber laser cutting machine affects the cutting accuracy, especially the diameter of the focal spot. The diameter of the focal spot should be as small as possible to produce a narrow slit; 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 of the fiber laser cutting machine and the distance between the workpiece and the nozzle also affects the power reduction of the fiber laser cutting machine. A distance too far can cause unnecessary waste of kinetic energy, while a distance too close can affect the dispersal ability of sputtered cutting products. The appropriate distance is 0.8mm. In addition, the fiber laser cutting machine mainly relies on its dynamic adjustment to cut workpieces with uneven surfaces, and the height of the nozzle and the workpiece should always be consistent during operation.

 

Once again, the cutting speed of the fiber laser cutting machine has a significant impact on the power of the fiber laser cutting machine, and the cutting speed is directly proportional to the power of the fiber laser cutting machine. The cutting quality is related to the quality of the laser beam, as well as the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a significant impact on the quality of laser cutting.

 

Next is the auxiliary gas for the fiber laser cutting machine. The size of the auxiliary gas and gas pressure also affect the power of the fiber laser cutting machine. It is best to use compressed air or inert gas as the auxiliary 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 edge frosting.

 

Finally, the laser power of the fiber laser cutting machine is considered to have decreased only if the first four items have been ruled out. Any device will experience some component aging after prolonged use. Laser is the most core and important component of fiber laser cutting machine, and power reduction may also occur after long-term use. In addition to the above points, the performance, size, and thickness of the processed materials can also affect the power reduction of the fiber laser cutting machine.

      1. Pay attention to the maintenance of fiber laser cutting machines. The fiber laser cutting machine has been processing for a long time, and many parts will wear and tear, which will inevitably affect the performance of the processing equipment. Therefore, maintenance is very important. For vulnerable parts, they should be replaced regularly; Optical components should be wiped clean and kept clean after use; Bearings should be regularly oiled to maintain driving flexibility and machining accuracy.
2. Standardize the operation of fiber laser cutting machines. The fiber laser cutting machine should be operated by a dedicated person. Before getting started, it should be trained by professionals: correctly executing the on/off sequence is crucial, familiarizing oneself with various switch panel buttons, correctly operating the fiber laser cutting machine, and so on. Specialized operation is not only beneficial for the normal operation of fiber laser cutting machines, but also reduces the probability of safety accidents.

        1. Power: After prolonged use of the machine, the laser power will more or less decrease, which will directly affect the cutting performance of the laser cutting machine;
2. Distance: The distance between the workpiece and the nozzle also affects the cutting effect of the laser cutting machine, so it is necessary to adjust the appropriate distance to not affect the performance of the cutting;
3. Position: The focus position directly affects the cutting progress. The diameter of the focus spot should be as small as possible, resulting in narrow cutting seams. If the cutting performance decreases, adjusting the focus position is a good method;
4. Long term overloaded production, lack of maintenance, and improper operation by operators are all reasons for the decline in cutting equipment performance.
Pay attention to the maintenance of the machine in daily life. Long term processing of fiber laser cutting machines can cause wear and tear on parts, which will inevitably affect the cutting performance of the machine. Therefore, daily maintenance is very important.
Standardize machine operation. Nowadays, larger fiber laser cutting machine manufacturers will arrange for customers to have dedicated personnel receive training on the machine operation process. Only after passing the training will they be arranged to operate on duty. The operation of dedicated personnel is not only conducive to the normal operation of fiber laser cutting machines, but also effectively avoids safety accidents.
