1. Confirm whether the output power of the laser cutting machine is sufficient. If the output power of the laser cutting machine is not enough, the metal cannot be effectively vaporized, resulting in excessive slag and burrs.
Solution: Check whether the laser cutting machine is working normally. If it is not normal, it needs to be repaired and maintained in time; if it is normal, check whether the output value is correct.
2. Whether the laser cutting machine has been working for too long, causing the equipment to be in an unstable working state, which will also cause burrs.
Solution: Turn off the fiber laser cutting machine and restart it after a period of time to give it a full rest.
3. Whether there is a deviation in the position of the laser beam focus, resulting in the energy not being exactly focused on the workpiece, the workpiece is not fully vaporized, the amount of slag generated increases, and it is not easy to blow off, which is easy to generate burrs.
Solution: Check the laser beam of the cutting machine, adjust the deviation position of the upper and lower positions of the laser beam focus generated by the laser cutting machine, and adjust it according to the offset position generated by the focus.
4. The cutting speed of the laser cutting machine is too slow, which destroys the surface quality of the cutting surface and generates burrs.
Solution: Adjust and increase the cutting line speed in time to reach the normal value.
5. The purity of the auxiliary gas is not enough. Improve the purity of the auxiliary gas. The auxiliary gas is when the surface of the workpiece evaporates and blows away the slag on the surface of the workpiece. 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 the formation of burrs.
Solution: The fiber laser cutting machine must be equipped with an air compressor during the cutting process, and use auxiliary gas for cutting.Replace the auxiliary gas with high purity.
