We all know that the laser cutting machine is a sharp tool for sheet metal processing, cutting iron like mud. In the actual production process, we often find that the processed materials will rust, especially in the south, which is relatively wet. Carbon steel, iron plate, etc. are easy to rust, so what should be paid attention to when laser cutting machine cuts the rusty materials?
We need to analyze the cutting principle of laser cutting machine first. The laser itself cannot become a light source. The laser will generate heat only after the surface of the processed sheet metal is absorbed. 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 the following effects
The cutting efficiency of rust plate will be reduced, the effect will be poor, and the scrap rate will be higher. If conditions permit, it is better to reduce the use of rusty plates or treat rusty plates in use.
In fact, the holes will burst during drilling and cutting, which will pollute the lens. You can use a grinder to remove the rust first. If the plate is not thick, the impact below 5MM will be small, but the cut product quality will be affected, and the unqualified rate is high.
The effect of cutting the uniformly rusted plate is better than that of uneven rusted plate. Because the whole uniformly rusted plate absorbs laser evenly, it can be cut well. For the processing of materials with uneven rust on the surface, the surface condition of materials shall be uniform before cutting.
