Causes and solutions for burrs produced by laser cutting machines

The most common problem of laser cutting machine in the processing process is that it is easy to produce burrs. The specific performance is that irregular metal remnants such as sharp corners and burrs will appear during the transition of the workpiece surface. However, common does not mean that the generation of burrs is acceptable. It directly affects the dimensional accuracy, shape and position accuracy and surface roughness of the processed parts, reduces product quality, and brings subsequent inspection, assembly, use performance and aesthetics. There are many problems, so burrs should be avoided as much as possible.

Common causes and solutions for burrs produced by laser cutting machines
Cause 1: The laser cutting machine produces up and down deviations in the focus of the laser beam, resulting in energy that cannot be concentrated on the workpiece, and the workpiece is not completely evaporated, which leads to an increase in slag, which is not easy to blow off and more likely to produce burrs.
Solution: Adjust the focus position of the laser beam, and adjust it to the best state according to the offset position it produces.
Cause 2: The output power of the laser cutting machine is not enough to effectively vaporize the metal, resulting in excessive slag and burrs.
Solution: Check whether the laser cutting machine is working properly. If not, repair it in time. If yes, please check if the output is correct.
Cause 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.
Solution: Adjust and increase the cutting line speed in time to make it reach the normal value.
Cause 4: The purity of the auxiliary gas of the laser cutting machine is not up to the required standard, which will also cause the workpiece to produce burrs.
Solution: Replace the auxiliary gas with higher purity.
Cause 5: The working time of the laser cutting machine is too long, which makes the equipment appear unstable, which will also lead to burrs.
Solution: Turn off the laser cutting machine and restart it after a period of time so that it can be fully rested.
I believe that the above methods can help you to solve the problems of burrs and dregs during the laser cutting process!
