Guys, how does this stuff turn and mill? Mostly mill.
It is ASTM B7777 Class 1.
I have in a distant past work with Tungsten, but tiny little things, all done on a Hardinge and a BP.
These are rather huge, 5" dia x 8" long, straight dia on the OD with a couple of O-ring grooves, so actually not concerned too much about the turning, but damned there is a lot of material coming off the middle!
Deep pockets ( like 3.5" deep ), large blind bores and only a few small(er) holes for 10-32 tapped and a couple of slip fit dowels.
The only good thing I see is that none of the pockets are sharp corners, all have at least a .062 fillet...
I am not at all concerned about making time on these, just want to know what to expect for tool life?
Again, there is about 60% of the material getting mauled off, and I am hoping to have the tools last through at least one piece.
Thank You
