Is the fiber laser marking machine able to cut?
The marking machine able to cut or not, that is the most question I was asked when I was in Shanghai for APPP EXPO last week. During the EXPO, we displayed our fiber laser marking machine to audiences. We run this machine, let it to mark, to engrave. And because of the effect is perfect. Our machine attracted lots of customers to circusee. Because we engrave the stainless steel and aluminum on the EXPO, so many customer ask us the question. Whether it can cut?
So first, in principle, yes, the machine is able to cut metal indeed. But it is not same like laser cutting machine. Because of the laser source are different,the laser source of fiber laser marking machine is pulse laser. However, laser source of fiber laser cutting machine is continuous laser. The laser type is different. The more important is fiber laser cutting machine’s laser power stronger than fiber laser marking machine a lot.
So the fiber laser cutting machine is much easier to cut metal sheet than fiber laser marking machine. And when we use laser marking machine to cut metal, In principle, this is a process of repeat marking. Base on our knowledge, laser mark once will left 0.01m‘s depth on material. So if people want to cut metal by laser marking machine, in principle, you need let the machine repeat over and over again. And wait for a long time, then the materials should be cut off by the machine.
So, how about in reality? Is the machine able to do that. If you really want to cut some metal by fiber laser marking machine. First you need enough time to wait, after you confirm your material’s thickness. Then you can start the machine to do it right away. And the laser craft is a kind of heat treatment, so ensure pause the machine after a while, let the material be cool. If the machine continuous processing, the material is easy to out of shape. And the focal depth is limit. So ensure the focal point is on the surface as well.
