When talking about laser cutting machines, some people think their equipment is easy to use, while others think their equipment is not. Laser cutting replaces traditional mechanical processing. It has the characteristics of high precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting saves materials, smooth incision, low processing cost, etc. Then why do some enterprises feel that it is not as easy to use as they imagined? It can be checked from the following aspects:
1. Check the focus position, which will affect the precision of laser cutting, especially the diameter of the focus spot. Focus spot diameter should be as small as possible to create a narrow slit.
2. Set a suitable distance between the nozzle and the workpiece. Too long distance will cause unnecessary waste of kinetic energy, and too close distance will produce strong return pressure on the lens, weaken the ability to disperse the splash cutting material production point, and have a negative impact on the cutting quality. The appropriate distance is 0.8 millimeters. In addition, it is necessary to ensure that the height of the nozzle and the workpiece is consistent during operation
3. Check the cutting speed, which is proportional to the power of the fiber laser cutter. At the same time, the size of laser beam after focusing has a great impact on the quality of laser cutting.
4. 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 reduced appropriately. Cutting with lower air pressure can prevent the edge from frosting.
5. Detect the laser power. The laser is the core component of the metal laser cutting machine, and the power will drop after long-term use. In addition, the performance, size and thickness of the processing materials may also affect the power of the laser cutting machine.
Finally, it is emphasized that, in addition to the above factors that affect the efficiency of the laser cutting machine, daily machine operation needs to pay attention to the problem of cutting smoke and dust removal. The laser cutting machine will produce smoke and dust in the cutting process, which may cause pollution to its precision parts. If not treated, the service life and cutting performance of the laser cutting machine will be affected.
