I was given a pallet of heat treated 718 Inconel (about 1500 pounds). I have never machined this alloy before and I've just been playing around with some scraps. I have tried HSS, carbide and ceramic inserts and not having a lot of luck with the finish. I have tried various coolants, feeds and speeds and just don't seem to be able to have much luck with it. I don't have a hardness tester so I can't offer much there, but was told it was heat treated. Has anyone else used this material and if so could you offer any tips? Thanks very much.
