During the use of the fiber laser cutting machine, the laser cutting head is unstable, the plate is bumped or the following distance is incorrect, which is generally caused by the replacement of the cutting nozzle, the cutting nozzle is overheated, and the parameters are not equal. In either case, in the final analysis, the capacitance value of the follower head changes, which affects the stability of the laser cutting head. How to deal with the follower plate of laser cutting machine?

If the laser cutting head of the fiber laser cutting machine is unstable, re-measure the capacitance value and save the parameters. Summarize the following experiences and analyze how to solve this situation in YAG equipment.

1. The laser cutting head is normal after hitting the plate. This is usually a parameter problem. You can reduce the upper limit and lower limit of the laser cutting head in the same proportion, and the laser cutting head will follow normally.

2. The following distance of laser cutting head is too high. Open the servo head debugging software and observe whether the following distance is set correctly; Adjust the upper limit value and lower limit value of the cutting head, increase in the same proportion, and test to the appropriate value.

3. During the cutting process, the laser cutting head suddenly rises automatically. In this case, stop the laser operation and observe whether the copper nozzle of the follower is hot. If it is hot, it means that the laser optical path is not correct, causing the copper nozzle to overheat and the capacitance value to change. The problem can be solved by adjusting the light path.
