Carbon? As in solid carbon? For EDM electrodes? Or do you mean carbon fiber composite? Big difference. You specified some dimensions but, I don't know if that's round electrodes or thickness of sheet material.
You should also be a bit more specific on the sizing if this is for cured carbon fiber material. Sizes of machines vary greatly.
I'll also prepare you (if this is indeed the material you're talking about): cutting carbon fiber is VERY hard on VERY expensive cutters (carbide or diamond). There is no cheap way to cut the stuff: high or low precision.
Oh yeah: the dust is also bad juju so, whoever does it will need adequate dust collection, respirators, etc. It's also very hard on machine parts so whoever bids will likely have to factor in the wear & tear it places on their machine.
Not trying to b a nay-sayer, just trying to prepare you for the quotes to come or lack thereof.
Edit: never mind. I see from your post history what we're talking about. We've been through this before. Carry on.
