Everyone knows that the laser cutting machine is an artifact that cuts iron, but the laser of the laser cutting machine cannot do anything to the surface of rust. Because the laser itself cannot be a light source, heat will only be generated after being absorbed through the surface of the sheet metal workpiece. For non-rusted materials and rusted materials, the laser absorption is very different, and the cutting effect is also different.
Taking a rusted sheet less than 5mm as an example, the cutting condition of a uniformly rusted sheet as a whole will be better than that of an unevenly rusted sheet. Because the overall uniform and rusty plate absorbs the laser light evenly, it can cut well. For material processing with uneven rust on the surface, the surface condition of the material should be uniform before cutting. Of course, if conditions permit, it is still recommended to use a sander to remove rust.
For thick rusted plates, if a rusted sheet is cut directly with a laser cutting machine, it is easy to cause the phenomenon of impervious cutting, the cutting quality is not good, and even the phenomenon of slag splashing may occur, which may cause Damage protection lenses and even focusing lenses can cause ceramic bodies to burst. Therefore, if you are cutting thick rusty materials, you must first remove the rust before cutting.
Laser Cutting Machine then can work smoothly on the rusted metal surface. And with the new technology , more and more technology can provide high effiency rust removal function.
