Sappiamo tutti che una macchina per il taglio laser è uno strumento affilato per la lavorazione della lamiera, che taglia il ferro come il fango. Nel processo produttivo vero e proprio, spesso troviamo che i materiali lavorati arrugginiscono, soprattutto al sud, che è relativamente umido. Acciaio al carbonio, piastre di ferro, ecc. sono soggetti a ruggine.
What should be paid attention to when laser cutting machine cuts rusty materials?
Firstly, we must analyze the taglio principle of the laser cutting machine. The laser itself cannot be a light source. The laser will only generate heat after the surface of the processed sheet is absorbed. In the case of rusty or non-rusty material surfaces, the laser absorption is different, and the heat generation is also greatly affected. Generally cutting rusty plates will have the following effects
The cutting efficiency of rusty plates will be reduced, the effect will be poor, and the scrap rate will be higher. If possible, reduce the use of rusty plates or treat them before use.
The biggest damage is actually blasting during punching and cutting, which will cause pollution to the lens. You can use a grinder to remove rust first. If the plate is not thick, the effect below 5mm will not be significant, but the quality of the cut product will be affected. The qualification rate is high.
The cutting condition of uniformly rusted plates will be better than that of unevenly rusted plates. Because the uniformly rusted sheet absorbs the laser evenly, it can be cut well. For material processing with uneven rust on the surface, the surface condition of the material must be even before cutting.
