When laser cutting of stainless steel and aluminum-zinc plate, the occurrence of burrs on the workpiece occurs. Firstly, the factor of burr when dividing low-carbon steel is considered, but the cutting speed cannot be simply accelerated, because the speed of the plate sometimes does not wear. In this case, this situation is particularly prominent when processing aluminum-zinc sheets. At this time, it should be considered comprehensively considering other factors of the machine tool, such as whether the nozzle should be replaced or not, and the movement of the guide rail is unstable. When laser cutting low carbon steel, the workpiece has burrs. According to the work and design principle of CO2 laser cutting, the following reasons are the main reasons for the burrs of the workpiece:
The upper and lower positions of the laser focus are not correct. It is necessary to do the focus position test and adjust according to the offset of the focus; the output power of the laser is not enough, and it is necessary to check whether the work of the laser generator is normal. If it is normal, observe whether the output value of the laser control button is correct and adjust it; the line speed of cutting is too slow and needs to be controlled in operation. Increase the line speed during control; the purity of the cutting gas is not enough, it is necessary to provide high-quality cutting working gas; the laser focus shift, need to do the focus position test, adjust according to the offset of the focus; the machine running time is too long Stability, you need to shut down and restart at this time.
