Laser cutting has been common in sheet metal cutting. Because of its high efficiency and high cutting quality of finished products, it has become the standard configuration of sheet metal processing stations. However, when some customers use the laser cutting machine, there are many burrs on the workpiece cut. Many people think that it is the quality problem of the laser cutting machine product, but not necessarily.

In the process of sheet metal processing, the gas purity and parameter setting of the laser cutting machine will affect the processing quality. If the equipment + gas + parameters are adjusted properly, the workpiece cut will be free of burrs.

How does burr come into being?

In fact, burrs are excessive residue particles on the surface of metal materials. When the laser cutting machine is processing the workpiece, the energy generated by the laser beam irradiating the workpiece surface vaporizes and evaporates the workpiece surface to achieve the purpose of cutting. But here is a device that we should pay attention to, which is gas.

Gas is to blow off the slag on the surface of the workpiece after the irradiation surface of the workpiece is vaporized. If gas is not used, the slag will form burrs on the cutting surface after cooling. Therefore, the purity of the gas should be high. You can change to a higher quality gas supplier. The purity of the gas is very important. Do not use cylinder gas, because after two filling, the purity is not good and the gas is wasted.

Another reason is the quality problem of the equipment itself, as well as the parameter setting factor. Therefore, when customers buy laser cutting machines, they should have experienced operators debug the equipment. Therefore, we should try to adjust the cutting parameters to the best. The air pressure, flow, focal length, cutting speed and so on must be adjusted many times. It is impossible to cut high-quality workpieces by relying on the parameters provided by the machine.

If a material has burrs, then the material can be identified as defective. The more burrs, the lower the quality.

Generally speaking, when the laser cutting machine has burrs, the following aspects can be checked and solved:

1. 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 time. If it is normal, check whether the output value is correct.

2. The vertical position of the focal point of the light beam deviates.

Solution: adjust the position of the focus according to the offset position.

3. The purity of the gas in the cutting machine is not enough.

Solution: change the gas.
