Can laser cutting machines cut rusty iron plates?

We all know that laser cutting machines are sharp tools for sheet metal processing, and they can cut iron like mud. In the actual production process, we often find that the processed materials will be rusty, especially in the south, which is relatively humid. Carbon steel, iron plates, etc. are prone to rust. So what should laser cutting machines pay attention to when cutting rusty materials? SAN LASER will explain it to you today.

We must first analyze the cutting principle of the laser cutting machine. The laser itself cannot be a light source. The laser will only generate heat after being absorbed on the surface of the processed sheet. In the case of rusty or rust-free material surfaces, 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 rusty plates will be reduced, the effect will be worse, and the scrap rate will be higher. If conditions permit, it is better to reduce the use of rusty plates or treat rusty plates before use.

The biggest damage is that holes will burst during drilling and cutting, which will pollute the lens. You can use a grinder to remove rust first. If the plate is not thick, the impact will not be significant below 5MM, but the quality of the cut product will be affected, and the failure rate will be high.

The cutting condition of the plate with uniform rust will be better than that of the plate with uneven rust. Because the plate with uniform rust absorbs the laser evenly, it can be cut well. For the processing of materials with uneven rust on the surface, the surface condition of the material should be uniform before cutting.
