Laser cutting machine in the process of cutting as long as the correct method of operation is generally no problem, cutting effect is very good. But if we use laser cutting machine to cut when there are some burrs, we need to pay attention to it. It is the best to find out the specific reasons and solve them in time.
Laser cutting machine is 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. But when some customers use laser cutting machine, there are many burrs in the workpiece. Many people think it is the quality problem of laser cutting machine products, but it is not always the case.
In the process of sheet metal processing, the gas purity and parameter setting of laser cutting machine will affect the processing quality. If the equipment + gas + parameter is adjusted well, the workpiece is free of burrs.
How is burr produced?
In fact, burr is the surface of metal materials too much debris particles. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the workpiece surface makes the workpiece surface vaporize and evaporate to achieve the purpose of cutting. But here's a device that we need to pay attention to, which is gas.
Gas is to blow off the slag on the surface of the workpiece after the gasification of the irradiation surface of the workpiece. If gas is not used, the slag will form a burr attached to the cutting surface after cooling. Therefore, the purity of gas should be high. You can change to a gas supplier with higher quality. The purity of gas is very important. Do not use cylinder gas, because after two filling, the purity is not good and gas is wasted.
Another reason is the quality problem of the equipment itself, and the parameter setting factor, so when the customer purchases the laser cutting machine, he should let the experienced operator debug the equipment. Therefore, it is necessary to adjust the cutting parameters as well as the cutting speed of air pressure flow focal length, which needs to be adjusted many times. It is impossible to cut high-quality workpiece by the parameters provided by the machine.
If a material has burr, the material can be qualitatively defective. The more burr, the lower the quality is naturally. Specifically, when the laser cutting machine has burr, the following aspects can be checked and solved. 1. The upper and lower position of the focus of the beam has deviation.
Solution: adjust the focus position according to the offset position.
2. The output power of laser cutting machine is not enough.
Solution: check whether the laser cutting machine works normally. If it is abnormal, it needs to be repaired and maintained in time. If it is normal, check whether the output value is correct.
3. The wire cutting speed of the cutter is too slow.
Solution: adjust the wire cutting speed in time.
4. The gas purity of the cutter is not enough.
Solution: change gas.
5. The laser beam of the cutter is offset.
Solution: debug the focus and adjust it in time
6. The instability caused by the long operation time of laser cutting machine.
Solution: shut down the machine and restart it and let it rest.
Fiber laser cutting machine is a precise machine, often a data error will cause its abnormal operation, so in the work to be strict, reduce errors.
These are some factors that may lead to the burr of laser cutting machine and specific treatment measures. I hope you can solve this problem when you are faced with it.
