Laser cutting machines have become very common in sheet metal processing. Due to their high efficiency and good finished product effect, they have become standard equipment for many sheet metal processing manufacturers. However, some customers use laser cutting machines to produce a lot of burrs on the workpiece. Many people believe that it is a quality issue with laser cutting machines, but it is not always the case.
During 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 do burrs come about?
Burrs are excessive residue particles on the surface of a metal material. When a laser cutting machine is processing a workpiece, the high energy generated by the laser beam irradiating the workpiece surface rapidly vaporizes and vaporizes the workpiece surface to achieve the purpose of cutting. But there is a core device that we must pay attention to, which is the auxiliary gas.
Auxiliary gas is used to blow off the slag on the surface of the workpiece after the irradiated surface of the workpiece is gasified. If auxiliary gas is not used, the slag will form burrs and attach to the cutting surface after cooling. Therefore, the purity of the gas is crucial to its high purity, and a gas supplier with better quality can be selected.
Another reason is the quality problem of the equipment itself, as well as the parameter setting factor. Therefore, when customers purchase a laser cutting machine, it is necessary to have a professional operator 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 there are burrs in laser cutting, the following aspects can be investigated and resolved
1. Deviation in the upper and lower positions of the focus of the light beam
Solution: Adjust the position of the focus and adjust it according to the offset position generated.
2. The output power of the laser cutting machine is insufficient
Solution: Check whether the laser cutting machine works normally. If it is abnormal, it needs to be repaired and maintained in a timely manner. If it is normal, check whether the output value is correct.
The wire cutting speed of the cutting machine is too slow
Solution: Timely adjust and improve the wire cutting speed.
4. The purity of the auxiliary gas of the cutting machine is not enough
Solution: Explain how to improve the purity of the auxiliary gas
5. The addition point of the laser beam of the cutting machine has shifted
Solution: Conduct focus debugging and timely adjustment
6. Instability caused by long operation time of laser cutting machine
Solution: Shut down the machine, restart it, and let the machine rest
Optical fiber laser cutting machine is a precise machine, and its operation is also a delicate task. Often, a data error can cause abnormal operation of its work. Therefore, it is necessary to be rigorous and meticulous in work to reduce and avoid errors.
