Metal laser cutting machine often cuts carbon steel, stainless steel, iron plate, and other metal plates. Due to the humid weather, the plates are easy to rust. When using the cutting machine, users often ask if they can cut these rusty plates? Will cutting rusty plates cause damage to the cutter?
First of all, we analyze the cutting principle of laser cutting machines. The laser itself can not be a light source, and the heat will be generated after the laser is absorbed on the surface of the processed sheet metal parts. In the case of rusty or non-rusty materials, the laser absorption is different, and the heat generation will be greatly affected. Generally, cutting rusty plates will have the following effects.
1. When cutting the cutting head, due to the influence of rust spots, it will produce the phenomenon of jumping, which will affect the stability of the cutting head and the qualification rate of the cutting workpiece.
2. The cutting efficiency of the rusted plate will be reduced, the effect will be poor, and the scrap rate will be high.
3. The metal cutting machine will explode when drilling and cutting, causing pollution to the lens.
4. The cutting condition of the overall uniform rusted plate is better than that of the uneven rusted plate. Because the whole rusty plate absorbs laser evenly, it can be cut well.
Suggestion: rust treatment should be carried out when cutting rusty plates. It is better to remove or average the rust.
