1. Stainless steel surface rusts.
It is difficult to cut through the stainless steel after rusting, and the cutting effect will also be affected, and there is rust blocking, which may make it easy for the laser cutting to shoot back to the nozzle, burn the nozzle and cut the damage, and high temperature will also damage the components. Once the nozzle changes, the laser spraying on the cutting may be offset, resulting in inaccurate spray nozzle, which will also damage the optical system and protection system, Even cutting and explosion accidents occurred. Therefore, do a good job of rust removal before cutting.
2. The stainless steel surface is coated with film.
Stainless steel surface coating is often encountered during processing, but it is completely impractical if the traditional cutting process is followed. When cutting brushed or mirror stainless steel, we usually use the cutting technology with film. In order to ensure that the film is not damaged, we usually cut the film side first, and the side without film is downward.
3. Stainless steel surface painting
This happens rarely, but it also needs attention. Because many paints contain toxic substances, it is easy to produce toxic smoke when cutting, which will be harmful to human body. Therefore, when using laser cutting machine to paint stainless steel, the surface paint should be wiped off first.
