How are burrs produced? In fact, burrs are excessive residue particles on the surface of metal materials. If a material has burrs, it can be identified as defective. The more burrs, the lower the quality. By analyzing the working principle and technology of the fiber laser cutting machine, the causes and solutions of burr are obtained:
1. There is a deviation between the upper and lower positions of the beam focus.
Solution: adjust the position of the focus and adjust it according to the offset position generated by the focus.
2. The output power is insufficient.
Solution: check whether the fiber laser cutting machine works normally. If it is abnormal, it needs to be repaired and maintained in time. If it is normal, please check whether the output value is correct.
3. The wire cutting speed of the fiber laser cutting machine is too slow.
Solution: timely adjust and improve the wire cutting speed.
4. The purity of the auxiliary gas of the fiber laser cutting machine is not enough.
Solution: explain how to improve the purity of auxiliary gas.
5. Check the laser beam of the cutting machine. The loading point may be offset.
Solution: debug the focus and adjust it in time
6. The working time of the cutting machine is too long, resulting in instability.
Solution: shut down and restart the fiber laser cutting machine, and then stop the machine.
When the optical fiber laser cutting machine processes the workpiece, the high energy generated by the laser beam irradiates the workpiece surface to vaporize and evaporate the workpiece surface to achieve the purpose of cutting. But there is a core equipment that we must pay attention to, that is, auxiliary gas. The auxiliary gas is the slag blown off the workpiece surface when the workpiece surface evaporates. If the auxiliary gas is not used, the slag will form burrs attached to the cutting surface after cooling. This is the main reason for burr formation.
