How to stay away from the burrs produced by the laser cutting machine ？

The most common problem in the processing of laser cutting machines is that they are prone to burrs. Generally speaking, there will be irregular metal parts such as sharp corners and burrs at the transition of the workpiece surface.It directly affects the dimensional accuracy of machined parts. This also brings a lot of problems to the follow-up inspection, assembly and use. Therefore, burrs should be avoided as much as possible.

Common causes for burrs

  1. The laser cutting machine produces a deviation in the position of the focus of the laser beam. It causes the energy to not converge on the workpiece. The workpiece is not fully vaporized, the slag increases, and it is not easy to blow off, which makes it easier to produce burrs.

  2. The output power of the laser cutting machine is not enough. Therefore, the machine cannot effectively vaporize the metal. This produces excessive slag and burrs.

  3. The cutting line speed of the laser cutting machine is too slow, which destroys the surface quality of the cutting surface and produces burrs.

  4. The purity of the auxiliary gas of the laser cutting machine is not up to the required standard.

  5. The laser cutting machine has been working too long. It leads to unstable working conditions of the equipment,will also cause burrs.

solution for burrs

  • Adjust the position of the focus of the laser beam, and adjust it to the best state according to the offset position it produces.

  • Check the working condition of the laser cutting machine. If it is not normal, needs to be repaired and maintained in time; if it is normal, check whether the output value is correct.

  • Adjust and increase the cutting line speed in time to make it reach the normal value.

  • Replace with higher purity auxiliary gas.

  • Turn off the laser cutting machine, and restart it after a period of time, so that it can be fully rested.

We need to correctly analyze the cause of the burr generated by the machine during cutting and choose the right solution.
