1. First check whether there is a problem with the laser output, and the light spot is not very round (the circle indicates that the transverse distribution of laser energy is uniform, and the energy distribution of the light spot formed after the lens Hui play is more uniform. Cutting quality is good)

2. Check whether the lens in the laser transmission process is dirty, or whether the lens is dirty, and whether the lens has small cracks that are not easy to find by the naked eye, which will affect the transmission of laser power.

3. The above two points are checked to determine whether the laser itself is good. Then comes the adjustment of process parameters. The burrs produced after laser cutting of stainless steel have a certain hardness and are difficult to remove. Must take time, but also affect the beauty of the workpiece. Address the root causes. The purity of the gas is higher, you can change a better quality gas supplier, the purity of the gas is very important, do not use the cylinder gas, because after two filling, the purity is not good, but also waste gas. Then the cutting parameters adjustment, pressure flow focal length cutting speed, after many adjustments, relying on the parameters provided by the machine is not cut out of the exquisite workpiece. Equipment + gas + parameters, adjust to the cut out of the workpiece is no burr.
