Laser cutting processing of stainless steel and coated aluminium zinc plate, artifacts have burrs generated is, first of all to consider the factors when cutting mild steel burr, but not simply speeds up the cutting speed, because of the increased speed sometimes plate cutting wear, the situation especially when processing coated aluminium zinc plate. At this time should be resolved to comprehensively consider the other factors of machine tools, such as whether to replace the nozzle, guide rail movement is not stable, etc. Laser cutting low carbon steel, artifacts appear burr, according to the work and the design principle of CO2 laser cutting, analysis the following reasons is the main cause of mechanical parts produce burr: fluctuation of laser focus position is not correct, you need to do to test focus position, adjust according to the offset of the focus; The laser output power is not enough, need to check whether the laser generator working normally, if the normal, is to observe the laser control button on the output value is correct, try to adjust; Cutting speed too slow, need to increase the linear velocity when operating control; Cutting gas purity is not enough, need to provide the high quality of cutting gas; Laser focus shifts, focus location test is needed to make adjustment according to the offset of focus, Machine tool operation instability time is too long, need to shutdown restart at this time.
