We all know that metal fiber laser cutting machines are sharp tools for sheet metal processing, cutting iron like mud. In the actual production process, we often find that the processed materials may rust, especially in the south, which is relatively humid. Carbon steel, iron plates, etc. are prone to rust. So what precautions should be taken when metal fiber laser cutting machines cut rusty materials?
What should be paid attention to when cutting rusty materials with a metal fiber laser cutting machine?
We need to analyze the cutting principle of a metal fiber laser cutting machine first. metal fiber laser itself cannot become a light source, and heat will only be generated when the metal fiber laser is absorbed on the surface of the processed sheet metal. In the surface condition of materials with or without rust, the metal fiber laser absorption is different, and the heat generation situation can also be greatly affected. Generally, cutting rusty plates can have the following effects
The cutting efficiency of rust plates will decrease, 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 them when in use.
The biggest harm is actually the explosion of holes during drilling and cutting, which causes pollution to the lens. A polishing machine can be used to remove rust first. If the plate is not a thick plate, the impact below 5mm is not significant, but the quality of the cut product will be affected, and the rejection rate is high.
The cutting effect of uniformly rusted boards is better than that of unevenly rusted boards. Because the overall evenly rusted plate absorbs metal fiber laser evenly, it can perform good cutting. For materials with uneven rust on the surface, the surface condition of the material should be uniform before cutting.
