i have a 2.75 dia OD shallow cup looking part. .350 oal with a few steps(turned dias on one side ) and a 2.0 dia flat face on the other side that tapers 2 deg. the OD also tapers 2 deg. the cup side is 2.5 ID and about .200 deep.
On my Mori i finish the ID and rough the steps and OD cutoff
then on my 16c lathe with an expanding id collet i finish the face and large od and 2deg angle with a OD Turn Tool, then i reach behind the od with a top notch and finish the steps and OAL(back edge)
I cant seem to get better than .0015 parallel, needs to be .001
All dia tolerances are +/-.001 with exception of the ID
I will say they have been made on these machines before but i just cant seem to get them this time. ive even switched to different heats from different mills and still no luck. Im hoping the Gods on here can lend a hand.
I cant post a drawing for aerospace reasons
