According to the working and design principles of fiber laser cutting, the analysis shows that the following reasons are the main causes of burrs in the workpiece:
The upper and lower positions of the laser focus are incorrect, and the focus position test needs to be performed and adjusted according to the offset of the focus;
The output power of the laser is not enough. You need to check whether the laser generator is working normally.
If it is normal, observe whether the output value of the laser control button is correct and adjust it.
The cutting line speed is too slow, so you need to increase the line speed during operation control;
The purity of the cutting gas is not enough, and high-quality cutting working gas needs to be provided; the laser focus is offset, and the focus position needs to be tested and adjusted according to the offset of the focus; the instability caused by the machine tool running for too long requires shutting down at this time Restart.
