Check the focus position of the laser beam:
The focus position of the laser beam is not adjusted to the appropriate position, and the energy cannot be well concentrated on the workpiece, which may cause the slag to not be blown away or evaporated in time during cutting, forming burrs.
Solution: Adjust the position of the laser beam focus and adjust the state based on the offset position it generates.
Adjust output power:
The output power of the laser cutting machine is too small, the energy is too small, and the heat is too low to fully utilize the molten metal, resulting in excessive residue and burrs.
Solution: Check if the laser cutting machine is working properly. If there are abnormalities, they should be maintained in a timely manner; If normal, the laser power should be adjusted to the appropriate size.
Check the purity of auxiliary gas:
The purity of the auxiliary gas in the laser cutting machine does not meet the regulations, which may also cause burrs on the workpiece.
Solution: Replace the high-purity auxiliary gas to ensure that the gas purity meets the required standards.
Adjust cutting speed:
The cutting speed of the laser cutting machine is too slow, which can damage the quality of the cutting surface and produce burrs.
Solution: Adjust the cutting rate in a timely manner to reach the standard value and avoid burrs caused by slow cutting.
Equipment rest and restart:
If the working time of the laser cutting machine is too long, it may cause unstable operation of the equipment and may also bring burrs.
Solution: Turn off the laser cutting machine and restart it after a period of time to get enough rest.
Choose appropriate materials and cutting parameters:
The problem of laser cutting burrs is closely related to materials, and different materials can have an impact on the cutting effect.
Solution: Select suitable materials and adjust corresponding parameters according to the characteristics of different materials during cutting, including cutting speed, power, gas flow rate, etc.
Adjusting gas flow rate:
Reasonable gas flow rate is a key factor in ensuring cutting quality. If the gas flow rate is not appropriate, it may cause material burning or insufficient removal of cutting slag, resulting in burrs.
Solution: During the cutting process, it is necessary to continuously adjust the gas flow rate according to the actual situation to achieve a good state.
