I am running a 2015 Haas TL 2, and was brought a prototype print for a firing pin that needs to be made. It's being made out of 17-4
The part length is 6.360 long, with a major O.D. of .280, a .075 step x. 470 from the face and a groove dia. of .156, .420 wide located 2.112 off the face.
I'm having problems with turning these small diameters.
I'm setting up a piece .375 between centers, and adjusting the protrusion from the chuck as I go to get as much stability as possible. I'm also grooving out .250 behind my countersink so I dont interfere with my live center and tailstock, and picking up z zero from there.
When I try to turn down the .075 diameter, and when I cut the groove, the .075 diameter keeps snapping off.
Does anyone possibly have a suggestion ? Maybe interpolation of that small diameter on the mill, vertically ?
