Reasons and Solutions for Burrs in Laser Cutting

Laser cutting machine is very common in sheet metal processing. Because of its high efficiency and high cutting quality, it has become the standard equipment of sheet metal processing station. However, when some customers use the laser cutting machine, many burrs will appear in the workpiece. Many people think that this is the quality problem of laser cutting machine products, but it is not always the case. Now let’s explain the causes and solutions of laser cutting machine burrs!
Several reasons for burrs during cutting:
1. The purity of the auxiliary gas of the laser cutting machine cannot meet the required standard, which will also cause burrs on the workpiece.
2. The cutting speed of the laser cutting machine is too slow, which will damage the surface quality of the cutting surface and produce burrs.
3. The output power of the laser cutting machine is insufficient and the metal cannot be effectively evaporated, resulting in excessive slag and burrs.
4. The working time of the laser cutting machine is too long, which makes the equipment unstable, and also causes burrs.
5. The deviation of the upper and lower positions of the laser beam focus generated by the laser cutting machine causes that the energy cannot be accurately concentrated on the workpiece, the workpiece is not fully vaporized, the number of slag generated increases, and it is not easy to blow off, so it is easier to produce burrs.
Reasons and Solutions for Burrs in Laser Cutting
Several methods for solving burrs:
1. Replace the auxiliary gas with higher purity.
2. Adjust and increase the cutting line speed in time to make it reach the normal value.
3. Adjust the focusing position of the laser beam and adjust it to the best state according to the offset position.
4. Turn off the laser cutting machine and restart it after a period of time to make it completely static.
5. Check whether the laser cutting machine works normally. If not, please repair it in time. If it is normal, check whether the output value is correct.
In fact, burrs are excessive residual 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 workpiece surface will vaporize the workpiece surface to achieve the purpose of cutting. If there are burrs in the material, it can be determined that the material is defective. The more burrs, the lower the quality. Therefore, we must pay more attention to this process in the future!
