1. The laser focus is not correct. The focal point of the laser with the highest energy is not focused on the metal sheet, resulting in burrs on the workpiece.
At this time, you need to test and adjust the focus.
2. Check whether the laser output value is correct. If it is too small, you need to increase the output power of the laser to ensure the cutting effect.
If the above two point are normal, please check whether the fiber laser source can work normally.
3. The auxiliary cutting gas is the guarantee of the cutting effect. If the gas purity is not enough, it will affect the excellent cutting effect. You need to choose high quality gas and increase gas pressure.
4. If cutting a quadrilateral, burrs appear on two adjacent edges, it indicates that the center of the light path is offset, and the center point of the light path from the nozzle shall be adjusted again; If burrs are on the two parallel edges, it indicates that there is a problem with the perpendicularity of the laser cutting head installed on the machine tool. The installation perpendicularity of the laser cutting head can be adjusted according to the burr direction on workpiece. Also you need to check whether the nozzle, it must be ensured that the nozzle mouth is a whole circle.
5. In order to improve production efficiency, enterprises will make the best use of equipment as much as possible. If you found that the high-power fiber laser cutting head runs for too long and causes burrs when cutting the workpiece, it is necessary to shut down and rest for a while, and then restart. People need to rest after working for a long time, then work efficiency can be improved, and the same is true for fiber laser cutting machines.
