1. Cutting rusty plates will reduce processing efficiency, cutting quality will also deteriorate, and product scrap rate will increase. Therefore, in the metal processing process, use rusty plates as little as possible, or treat rusty plates before using them.

2. During the cutting process, especially when the plate is punched, holes may explode, which will pollute the protective lens. The rusty plate needs to be treated first. Of course, the impact on the plate below 5MM is not great, mainly the rusty thick plate. Compared with the qualified plate, the cutting quality of the rusty plate still has an impact.

3. The overall uniform cutting effect is better than that of the uneven rusted plate. The overall uniform rusted plate absorbs the laser relatively uniformly and can be cut well. Inhomogeneous rusty sheet can not get a good cutting effect, it is recommended to treat the surface to make the surface of the sheet uniform, and then cut.
