Laser cutting machine is very common in sheet metal processing. Because of its high efficiency and good finished product effect, it has become the standard configuration of many sheet metal processing stations. However, when some customers use the laser cutting machine, they cut out a lot of burrs on the workpiece. Many people think it is a quality problem of the laser cutting machine, but it is not always the case.
In the process of sheet metal processing, the gas purity and parameter settings of the laser cutting machine will affect the final processing effect. When the equipment+gas+parameters are adjusted to the best, the workpiece cut is free of burrs.
How are burrs produced?
Burr is the excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the high energy generated by the laser beam illuminating the workpiece surface makes the workpiece surface vaporize rapidly and evaporate to achieve the purpose of cutting. But there is a core device that we must pay attention to, namely, auxiliary gas.
The auxiliary gas is used to blow off the slag on the surface of the workpiece after the surface of the workpiece is gasified. If the auxiliary gas is not used, the slag will form burrs attached to the cutting surface after cooling. Therefore, the purity of the gas is very important. The gas supplier with better quality can be selected.
Another reason is the quality of the equipment itself, as well as the parameter setting factors. Therefore, when customers purchase laser cutting machines, they must have professional operators debug the equipment. Air pressure flow, focal length, cutting speed, etc., and adjust the cutting parameters to the best.
The more burrs, the lower the quality. Specifically, when burrs appear in laser cutting, the following aspects can be taken for troubleshooting
1. The upper and lower positions of the beam focus deviate.
Solution: Adjust the focus position according to its offset position.
2. The output power of the laser cutting machine is not enough.
Solution: Check whether the laser cutting machine works normally. If it is abnormal, timely repair and maintenance are required. If it is normal, check whether the output value is correct.
3. The wire cutting speed of the cutter is too slow.
Solution: timely adjust and improve wire cutting speed.
4. The purity of the auxiliary gas of the cutter is not enough.
Solution: Explain how to improve the purity of auxiliary gas.
5. The addition point of the laser beam of the cutting machine has shifted.
Solution: Conduct focus debugging and timely adjustment
6. The laser cutting machine is unstable due to too long operation time.
Solution: Turn off the machine and restart it and let it rest.
The optical fiber laser cutting machine is a precise machine, and its operation is also a fine work. Often a data error will cause its operation to be abnormal. Therefore, it should be strict and fine in the work to reduce and avoid errors.
