Machining Tantalum, Rhenium, and Molybdenum...
Aug 01, 2018· I have machines pure moly and pure Niobium ( close to tantalum). The moly machined similar to a hard cast iron. I had chipping on the floor of a pocket which I remedied with an endmill with a corner radius. I tried face milling and it was horrible looking. Looked like it was tearing and smearing. Switched to a radius endmill and faced with that.
