During the use of the laser cutting machine, there will be situations where the metal laser cutting machine cannot cut through the material, which affects the processing quality of our laser cutting machine, wastes materials and also has a certain impact on the laser cutting machine.
Why does the laser cutting machine appear to be unable to cut through the laser cutting machine?
Under normal circumstances, the reasons why laser cutting cannot be cut through are:
1. Pollution of optical components: optical components include focusing mirrors, reflectors, etc., because they are in a poor working environment for a long time, it is easy to cause residues on the surface of such lenses, which reduces the laser power of the equipment, resulting in impenetrable cutting .
2. The auxiliary gas pressure of the equipment is not enough: the auxiliary gas is used to help blow off the residue during cutting. When the air pressure is not enough, the residue is difficult to remove, which will lead to impermeable cutting.
3. The power of the laser decreases: After the laser of the fiber laser cutting machine is used for a long time, the power will gradually decrease with the time of use, which will eventually lead to a decrease in the cutting ability and impenetrable cutting.
4. The cutting speed of the laser cutting machine is too fast: if the cutting speed is too fast, missed cuts will inevitably occur, which will lead to impermeable cutting.
5. Equipment light spot debugging is not up to standard: The light spot of the fiber laser cutting machine is the most important factor affecting the cutting quality. When the light spot debugging does not meet the standard, the cutting will not be transparent.
6. The thickness of the processed sheet exceeds the cutting thickness of the equipment limit: Fiber laser cutting machines with different powers will have a limit cutting thickness. If the limit thickness is exceeded, the cutting effect of the equipment will be unsatisfactory, including the situation of impervious cutting.
Solutions for products that cannot be cut through by laser cutting:
1. Check whether the power of the laser cutting machine has dropped. If so, we need to replace the laser tube in time, and use a smoother and larger voltage regulator to increase the laser current output and increase the output power.
2. When cutting, we need to reduce the cutting speed, clean the polluted mirror reasonably, and replace the focusing lens.
3. If the optical path is not correct, you can re-adjust the optical path and adjust the focal length until the laser makes a very round spot on the paper.
4. When cutting copper and aluminum, it is best to polish its surface in advance or apply light-absorbing materials to deal with the problem of high reflectivity.
5. Regularly clean the foreign matter in the nozzle, increase the pressure of the auxiliary gas, and replace the distilled water in the cooling system in time.
When we deal with the problem of impenetrable cutting, we can follow the above method. If we do every step well, then naturally there will be no phenomenon of impenetrable cutting or rough incision.
