After upgrading CO2 laser to fiber laser cutting, you will satisfy with the cutting efficiency and less cost i.e. elctrict cost, gas cost. Of course, you still need to maintain in daily life or after a period of time to see whether the laser cutting machine is normal, which parts need to be repaired, and whether the cutting head is still at the normal calibration level, etc. The damaged laser cutting machine of the parts can be directly and obviously manifested, but it is difficult to judge whether the laser cutting head is within the normal calibration level, so what methods can we find out?
1. Stability
As the most precise part of the fiber laser cutting machine-fiber laser, its performance is stable, and the service life of key components can reach 100,000 hours, so the output is very stable and does not appear deviation during the working process. When the laser is not very stable for a certain period of time and there is a small problem in the output, it can be judged with a high probability that it is not within the calibration level, and then it can be overhauled.
2. Verticality
For the fiber laser cutting machine, when the program is programmed, the cutting head will complete the cutting task according to the instructions of the program, so there will be no deviation in verticality. The verticality of the cutting edge is very important. The cutting edge deviates from the place specified by the program instruction, so that the cutting prototype does not meet the actual demand.
3. The width of the slit
The laser cutting head is focused into a small spot, so that the focal point can reach a high power density. The material is quickly heated to the degree of vaporization, and evaporates to form a hole. As the beam and the material move relatively linearly, the hole continuously forms a width Very narrow slit. The above can meet this requirement under normal circumstances, but when the laser head calibration fails, satisfactory narrow slits cannot be cut out and the entire line is not on a horizontal line.
4. Coaxiality judgment
During the calibration process of the fiber laser cutting machine, if the center of the airflow and the center of the beam are not on the same axis, the sparks will sputter unevenly in all directions when cutting the carbon steel plate. Carry out the carbon steel plate drilling test again to observe whether the spark sputtering is uniform, and if it is not uniform, make adjustments. After many repetitions, the coaxiality of the air flow center and the beam center will be adjusted to an ideal state.
