How to deal with the burr problem of laser cutting machine?

How do burrs come about? In fact, burrs are excessive particles of residue on the surface of metal materials. If a material appears burr, then this material can be qualitatively defective, the more burr, the lower the quality of nature. Through the working principle of fiber laser cutting machine, technical analysis, obtained the cause of burr and solution:

1. The upper and lower positions of the beam focus are deviated. Solution: Adjust the location of the focus and adjust it according to the offset of the focus. 2, the output power is insufficient. Solution: Check whether the fiber laser cutting machine works properly. If they are abnormal, they need to be repaired and maintained in time. If yes, check whether the output value is correct. 3, fiber laser cutting machine line cutting speed is too slow. Solution: Adjust and improve wire cutting speed in time. 4, the purity of the auxiliary gas of the fiber laser cutting machine is not enough. Solution: Explain how to improve the purity of the auxiliary gas.

4, the purity of the auxiliary gas of the fiber laser cutting machine is not enough. Solution: Explain how to improve the purity of the auxiliary gas. 5. Check the laser beam of the cutting machine. The loading point may be offset. 6. The working time of the cutting machine is too long, resulting in instability. Solution: Shut down the fiber laser cutter and restart it, then stop the machine from running.

When the fiber laser cutting machine processes the workpiece, the high energy generated by the laser beam irradiates the workpiece surface, so that the workpiece surface vaporizes and evaporates to achieve the purpose of cutting. But there is one core device that we must pay attention to, and that is the auxiliary gas. The auxiliary gas is blown away from the slag on the workpiece surface when the workpiece surface evaporates. If no auxiliary gas is used, the slag will cool and form burrs attached to the cutting surface. This is the main cause of burr formation.
