I'm trying to find an easier way to do the attached part.
Material is D2 tool steel, HT to about 62 RC. The small OD is 2 1/4, the larger one is 3".
The keyway is so long that a normal broach completely fills the gullets and I get tearing on the exit of the key.
The diameters get machined post HT.
Finish size of the bore is 1.440.
Keyway is .251-.252
I can rough machine the bore to any size to minimize WEDM time.
How much would it cost to skim the bore, and cut the keyway?
I've never seen a WEDM, so I haven't a clue about work holding.
It goes a bit wonky during HT, so would it be possible to keep it perpendicular to the larger diameters face?
Thanks for any advice,
Ed
