We are developing a forming tool that takes polished stainless strip and creates cylinders with it. We mark the strip with a part number and feed it through a forming section (forcing the strip into a flat angled piece of carbide) which causes it to curl into a cylinder and then we part it off.
The problem is that we are using a laser marking system and as the mark is forced into the carbide to form the radius bend, the laser mark scrapes along the carbide and the dark “slag?” powder that makes up the mark begins to build up on the carbide and eventually creates a hard lump on the surface of the carbide and begins to make scratches in the part.
We haven’t tried to lubricate the strip yet, but will try that next. However any lube we add will likely need to be washed off so we would like to avoid that if possible.
Anyone dealt with blunt forming of stainless steel strip that has been laser marked before forming? We don’t want to have to deal with laser marking after forming.
