The reason and solution for cutting the burr by the fiber laser cutting machine

fibe laser cutting machine from china

Fiber laser cutting machine have been common in sheet metal processing. Due to their high work efficiency and high quality of finished products, they have become the standard for sheet metal processing stations. However, some customers use the laser cutting machine to cut out the workpiece burrs, many people think that the quality of the laser cutting machine products, in fact, not quite. Now Xiaobian will explain the reasons and solutions for the occurrence of laser cutting machine burrs!

Some reasons for burrs in cutting:

1.The purity of the auxiliary gas of the laser cutting machine can not reach the required standard, and the workpiece will also produce burrs.
2.The cutting speed of the laser cutting machine is too slow, which destroys the surface quality of the cutting surface and produces burrs.
3.The output power of the laser cutting machine is not enough, and the metal is not effectively vaporized, thereby generating excessive slag and burrs.
4.The laser cutting machine works for too long, so that the equipment has an unstable working state, which will also lead to the occurrence of burrs.
5.The laser cutting machine produces a deviation of the upper and lower positions of the focus of the laser beam, so that the energy does not just converge on the workpiece, the workpiece is not fully vaporized, so that the amount of slag is increased, and it is not easy to blow off, so that burrs are more likely to occur.

Some ways to solve the glitch:

1.Replace the auxiliary gas with higher purity.
2.Adjust and increase the cutting line speed in time to reach the normal value.
3.Adjust the position of the focus of the laser beam and adjust it to the optimal state according to the offset position generated by it.
4.Turn off the laser cutting machine and re-start it after a while to get enough rest.
5.Check whether the laser cutting machine works 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.

In fact, burrs are excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam illuminating the surface of the workpiece vaporizes the surface of the workpiece and evaporates to achieve the purpose of cutting. If a material has a burr, then the material can be characterized as a defective product. The more burrs, the lower the quality naturally. Therefore, we must pay more attention to the future processing process!
