An article to understand the correct handling method of laser cutting machine cutting head hitting the board.

In the process of long-term use of laser cutting machines, processing manufacturers will inevitably have various failures, among which the cutting head hitting the board is a common failure. If you don't know how to deal with it, then by reading this article, you will understand the correct way to deal with the cutting head hitting the board.

The cutting head hitting the board of the laser cutting machine is a common fault, whether it is a fiber laser cutting machine or a CO2 laser cutting machine, it will appear. Don’t panic if you encounter this kind of board hitting during use, turn off the laser equipment and find the hitting board The source can be.

Fiber laser cutting machine

First of all, if the fiber laser cutting machine or CO2 laser cutting machine is unstable, the board will be bumped or the following distance is not correct. At this time, the cutting nozzle can be replaced. Or the cutting nozzle is overheated, the parameters are not correct, etc. It may cause the cutting head to hit the board.

But no matter what the reason is, it is basically because the capacitance value of the tunnel head changes, which leads to the stability of the laser cutting head. Whether it is a fiber laser cutting machine or a CO2 laser cutting machine whose cutting head is unstable, you can re-measure the capacitance value, reset and save the parameters.

CO2 laser cutting machine

It is normal for the cutting head of the fiber laser cutting machine or CO2 laser cutting machine to touch the board. This situation is usually due to the parameter setting. The upper limit and the lower limit of the laser cutting head can be reduced in the same proportion, and the laser cutting head follows It will be normal; the following distance of the laser cutting head is too high. Open the follow-up head debugging software and observe whether the following distance is set correctly; adjust the upper limit and lower limit of the cutting head, increase in the same proportion, and test to the appropriate value; during the cutting process, the laser cutting head suddenly rises automatically. When this happens, stop the laser work and observe whether the copper nozzle of the follower head is hot. If it is hot, it means that the laser light path is not correct, which causes the copper nozzle to overheat and the capacitance value changes. The problem can be solved by adjusting the optical path.

Everyone has basically understood the situation of the cutting head hitting the plate of the laser cutting machine. If the cutting head hits the plate in the future use, you can check the shutdown according to the method mentioned in this article, and then do other operations to avoid mistakes. Operation causes damage to machine parts.
