How to solve the burrs caused by laser cutting?–Winnie

Laser cutting machine is widely use in the sheet metal processing industry.

Because of its advantages such as high work efficiency, good quality of the finish product, flexible processing, etc.,

It has been increasingly favore by the sheet metal processing industry. However, when some customers use laser cutting machines, there are many burrs on the workpiece. Many people think that the quality of the laser cutting machine is defective. Is this the case?

Actually not necessarily. In the process of sheet metal processing, the parameter setting and gas purity of the laser cutting machine will affect the processing quality. Use a suitable and qualified gas, configure the machine and adjust the parameters so that the cut workpiece will not burr.

The burr is actually an excessive amount of residue particles on the surface of the metal material. When a laser cutting machine processes a workpiece, a laser beam is irradiat on the surface of the workpiece, and the energy generate causes the surface of the workpiece to vaporize to achieve the purpose of cutting.

When cutting, auxiliary gas is use to quickly blow off the slag on the metal surface, so that the cutting section is smooth without burrs. Different auxiliary gases are used to cut different materials. If the gas is not pure or the pressure is not enough to cause a small flow, the slag will not be blown clean and burrs will form.

Another reason is the setting of equipment parameters, such as the incorrect position of the laser focus.

If the workpiece has burrs, you can troubleshoot from the following aspects:

1. If the cutting gas is not pure enough, if not, replace it with a high-quality cutting auxiliary gas.

2. If the laser focus position is correct, you need to do a focus position test and adjust it according to the focus offset.

3. The output power of the laser is not 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 cutting speed of the cutting machine is too slow, it is necessary to increase the line speed during operation.

5. The machine runs for too long, causing the machine to be unstable. It needs to shut down and restarted to allow the machine to rest.
