Cutting nickel steel
First, this post is going to be somewhat vague as I'm under an NDA and
can't give much detail. That said, I have a need to cut 1/16" to 1/4" thick slices off of irregularly shaped objects composed of 5-10 percent nickel, 1-2 percent carbon, a few trace elements, and the rest iron. Annealing is not an option--they have to be cut as is. The objects may be somehwere in the range of 1 to 5 inches in diameter. The kerf has to be as narrow as possible. So far I've been using a diamond lapidary blade and oil coolant but it's really slow going and judging from the noises it makes the saw is not happy. It'll cut through a lump of slag in a minute or so, but one of these puppies takes a half an hour with the same setup. I was wondering if anybody had any ideas on a better way to go. |
