Fiber laser cutting machine is very common in sheet metal processing. Due to its high processing efficiency and good finished product effect, it has become the standard of many sheet metal processing stations. However, some customers have a lot of burrs on the workpieces cut when using fiber laser cutting machine. Many people think that it is a quality problem of laser cutting machine products, but it is not entirely true.

In the process of sheet metal processing, the gas purity and parameter settings of the fiber laser cutting machine will affect the final processing effect. The equipment + gas + parameters are adjusted to the best, and the workpiece cut out is burr-free.

How are burrs generated?

In fact, burrs are excessive residue particles on the surface of metal materials. When the fiber laser cutting machine is processing the workpiece, the high energy generated by the laser beam irradiating the workpiece surface causes the workpiece surface to vaporize and evaporate rapidly to achieve the purpose of cutting. But there is a core device here that we must pay attention to, that is, auxiliary gas.

The auxiliary gas is to blow off the slag on the surface of the workpiece after the irradiated surface of the workpiece is vaporized. 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 should be high. You can change to a gas supplier with better quality. The purity of the gas is very important. It is best not to use cylinder gas, because after two fillings, the purity is not good and the gas is wasted.

Another reason is the quality of the equipment itself, and the parameter setting factor. Therefore, when customers buy laser cutting machines, they must have professional operators debug the equipment. Therefore, try to adjust the cutting parameters to the best, such as air pressure, flow, focal length, cutting speed, etc., and adjust them many times. You can't cut exquisite workpieces by relying on the parameters provided by the machine.

If a piece of material has burrs, then this material can be qualitatively defective. The more burrs, the lower the quality. Specifically, when the fiber laser cutting machine has burrs, it can be checked and solved from the following aspects.

1. The upper and lower positions of the focus of the beam deviate.

Solution: Adjust the position of the focus according to the offset position it produces.

2. The output power of the laser cutting machine is not enough.

Solution: Check whether the laser cutting machine is working normally. If it is not normal, 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 cutting machine is too slow.

Solution: Adjust and increase the wire cutting speed in time.

4. The purity of the auxiliary gas of the cutting machine is not enough.

Solution: Explain to increase the purity of the auxiliary gas.

5. The addition point of the laser beam of the cutting machine has shifted.

Solution: Debug the focus and adjust it in time.

6. The laser cutting machine has been instability due to long operation time.

Solution: Turn off the machine, restart it and let the machine rest.

The fiber laser cutting machine is a precision machine, and the operation is also a delicate job. Often a data error will cause its operation to be abnormal. Therefore, it is necessary to be strict and meticulous in the work to reduce and avoid errors.
