1. First, check whether there is a problem with the laser output and whether the laser spot is very round (round means that the transverse distribution of the laser energy is uniform, and the energy distribution of the light spot formed after the lens emblem is more uniform. The cutting quality is good)
2. Check whether the lens is dirty during laser transmission, or whether the lens is dirty, and whether the lens has small cracks that are difficult to find by the naked eye, which will affect the transmission of laser power.
After the above two points are checked, it can be determined whether the laser itself is good, and then it is the adjustment of process parameters. The burrs generated after laser cutting of stainless steel have a certain hardness, which is difficult to remove. It must be time-consuming, but also affects the beauty of the workpiece. It is better to solve the problem from the root. The purity of the gas should be high. You can change to a gas supplier with better quality. The purity of the gas is very important. It is better not to use the cylinder gas, because after twice filling, the purity is not good and the gas is wasted. In addition, the cutting parameters should be adjusted to the best. The cutting speed of the air pressure flow focal length should be adjusted for many times. The parameters provided by the machine can not cut beautiful workpieces. Equipment+gas+parameters, adjusted to the best, and the workpiece cut is free of burrs.
