Reasons for Burr on Workpiece in Laser Cutting of Low Carbon Steel
According to the operation and planning principle of optical fiber laser cutting machine, the following reasons are analyzed:
1. The upper and lower positions of laser focus are incorrect. The orientation of focus should be tested and adjusted according to the offset of focus.
2. The output power of the laser is not good. We need to check whether the operation of the laser generator is normal. If it is normal, we need to investigate whether the output value of the laser control button is correct, and then adjust it.
3. The cutting line speed is too slow, so it needs to increase the line speed when operating.
4. The purity of cutting gas is not good, and high quality cutting gas should be supplied.
5. Laser focus offset needs focus orientation test, which is adjusted according to the offset of focus.
6. The instability of the machine tool when it runs too long. It needs to be shut down and restarted at the moment.
