Laser cutting equipment is a sharp tool for sheet metal processing. When processing plates, it is often found that there will be rust. What should be paid attention to when cutting rusty materials?
In the case of rusty or non rusty material surface, the laser absorption is different, and the heat generation will also be greatly affected. Generally, cutting rusty plates will have an impact.
The cutting efficiency of rust plate will be reduced, the effect will be poor, and the scrap rate will be high. If conditions permit, it is better to reduce the use of rust plates or handle the use of rust plates.
In fact, the major damage is that the holes will burst during drilling and cutting, which will pollute the lenses. You can use a grinder to remove the rust first. If the plate is not thick, the impact of less than 5MM will be small, but the quality of the cut products will be affected, and the unqualified rate is high.
The cutting condition of uniformly rusted plates as a whole will be better than that of non uniformly rusted plates. Because the overall uniformly rusted plate absorbs laser evenly, it can be cut well. For the processing of materials with uneven rust on the surface, the material surface shall be uniform before cutting. The laser cutting equipment shall pay attention to these matters when cutting rusty materials.
