The CNC fiber laser cutting machine has gradually replaced the CNC plasma cutting machine and is widely used in the sheet metal processing industry. Because of its advantages of high work efficiency, good quality of finished products, and flexible processing, it has been more and more favored by the sheet metal processing industry. However, when some customers use the CNC fiber laser cutting machine, the workpieces cut out have many burrs. Many people think that the quality of the CNC fiber laser cutting machine itself has problems. Is this true?

Not really. In the process of sheet metal processing, the parameter settings and gas purity of the CNC fiber laser cutting machine will affect the processing quality. Use suitable and qualified gas, deploy the machine, and adjust the parameters, and the workpiece will be cut without burrs.

Burrs are actually too many residue particles on the surface of metal materials. Such problems will occur when the CNC plasma cutting machine is working. When the CNC fiber laser cutting machine processes the workpiece, the laser beam is irradiated on the surface of the workpiece, and the generated energy vaporizes the surface of the workpiece to achieve the purpose of cutting. When cutting, auxiliary gas is used to quickly blow off the slag on the metal surface, so that the cutting section is smooth and free of burrs. Different auxiliary gases are used for cutting different materials. If the gas is not pure, or the flow rate is low due to insufficient pressure, the slag will not be blown cleanly and burrs will be formed.

Another reason is the setting of equipment parameters, such as the incorrect up and down position of the laser focus and so on.

If there are burrs on the workpiece, you can check from the following aspects:

1. Whether the cutting gas of the CNC fiber laser cutting machine is not pure enough, if not, replace the high-quality cutting auxiliary gas.

2. Whether the laser focus position is correct, it is necessary to do a focus position test and adjust it according to the offset of the focus.

3. Whether the output power of the laser is enough, check whether the laser works normally, if it is normal, observe whether the output value of the laser control button is correct, and adjust accordingly.

4. The wire cutting speed of the cutting machine is too slow, and it is necessary to increase the wire speed during operation.

5. The machine is unstable due to the long running time of the machine tool. It needs to be shut down and restarted to give the CNC fiber laser cutting machine a rest.

The above is the introduction of Jinan REBOUND CNC machine company about CNC optical fiber metal cutting.
