In the process of long-term use of laser cutting machines, there are unavoidably various mechanical failures. Among them, 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.

It is a common fault that the cutting head touches the board of the laser cutting machine, no matter for the fiber laser cutting machine or the CO2 laser cutting machine. While encountering this kind of situation, workers should calm down and just turn off the laser equipment and find the touch board.

Fiber laser cutting machine

First of all, if the fiber laser cutting machine or the CO2 laser cutting machine is unstable, there will be a situation that the board is bumped or the following distance is incorrect. At this situation, the cutting nozzle can be replaced. If the cutting nozzle is overheated and the parameters are not correct, which might cause the cutting head to hit the board.

But no matter what the reason is, it is basically because of change of the capacitance of the tunnel head, which leads to the instability of the laser cutting head. Whether it is a fiber laser cutting machine or a CO2 laser cutting machine whose cutting head is unstable, capacitance can be re-measured and the parameters can be reset and saved.

CO2 laser cutting machine

The cutting head of the fiber laser cutting machine or CO2 laser cutting machine is normal after touching the board. This situation is usually because of parameter setting problems. That might because laser cutting head is too high since the upper limit and lower limit of the laser cutting head in the same proportion. By checking, it is necessary to open the follow-up head debugging software and to observe whether the following distance is set correctly, also to adjust the upper limit and lower limit of the cutting head then test whether the value is appropriate. However, the laser cutting head will suddenly rises automatically during the cutting process. When that happens, the laser work must be stopped and workers should observe whether the copper nozzle of the follower head is heating up. If it is heating, it means that the laser light path is not correct, which causes overheat of the copper nozzle and the change of the capacitance. The problem can be solved only by adjusting the light path.

The situation of the cutting head hitting the board of the laser cutting machine can be understood basically. If the situation happened in the future, workers should turn off the machines then check the machines according to the method mentioned in this article, and then do other operations to avoid damaging the machine parts.
