During the use of optical fiber laser cutting machines, a laser head jitter is a common problem. This phenomenon affects the accuracy and effect of cutting. To solve this problem, we need to check and adjust from multiple aspects. Here are some ways to solve the problem of jitter.
1. Calibrate laser head
Before the cutting starts, the correct calibration is made. Open the racked mirror, find the calibration function, and then calibrate the whole process.
When calibrating, let the laser head close to the plate, keep the distance from about 5 mm to 1 cm, so that the machine is restless and prevent vibration. After the calibration is successful, save the settings.
2. Check the source of gas
Checking Qi source is also a very important step. Make sure that the gas valve on the gas cylinder is completely opened to ensure that the air flow can keep up.
If the air valve is not completely opened, the air flow cannot keep up, and the cut head may also shake.
3. Check the ground
Check whether the machine tool has undergone reliable grounding. First, check whether the ground line of the machine tool has been connected. There are ground lines at the total power supply of the machine to ensure that the ground line has been connected.
Because the height of the laser cutting head is induction through the capacitor, if the capacitor is too large or the static electricity of the machine tool is too large, the cut head may be beating up and down, so it is very important to connect the ground wire.
4. Check the focus position and air pressure
If a high -power laser cutting machine is used, you need to check whether the focus position is too high and whether the air pressure is too high.
If the focus position is too high, you can be lower; if the air pressure is too high, you can also be appropriately reduced.
5. Check the temperature and protect the lens after cutting
After the cutting is completed, you can touch the cutting site by hand to feel whether there is temperature or very hot. If it feels hot, it means that the focus may be too high and need to be appropriately reduced.
At the same time, check whether the protective lens is polluted. If there is pollution, the protective lens needs to be replaced.
The above is several solutions to the laser head jitter when the laser cutter works. During the operation, pay attention to safety, ensure that all equipment work properly, and avoid other problems.
