RE: Grinding solution for Hastalloy HVOF coating
what process are you using now for grinding the coating? Stone or belt?

We have had good experience with Belt grinding on all substrates and coatings....

Do you have any good results grinding nickel-base alloys round bars with belt grinding? Do you know if there is any commercially available belt grinder that can grind round bars? We would like to grind a lot of 1 inch bars made of superalloy. Actually we are turning it on outside diameter but it not easy process. We plan to test centerless grinding machine but we know that grinding nickel-base alloys is a hard case.
