Hi All:
I have some 1 mm diameter stub shafts to make: 0.200" long with an M1 x 0.25 thread for 0.086" long on one end.
The desired material is 17-4 PH at condition H900.
What are my chances of pulling it off by single point threading it instead of trying to threadmill it?
I ground a nice little carbide tool for it: 15 degrees relief on the leading flank and 5 degrees of relief on the trailing flank with zero rake so I'm good there.
I can have a couple of turns of thread runout, so no relief groove needed.
Would you turn it in 2 stages or do you think I can get away with threading it to final length in a single go?
Obviously I don't intend to turn the rest of the shaft until the thread is done.
BTW I did try cutting it with a button die...no go, and now I have a fucked up button die
Cheers
