Hardening drill rod - how to avoid dimensional changes?
(clip) Problem is that after hardening, the diameter of the parts increased
anywhere from .0005 to .0007. (clip)
^^^^^^^^^^^^^^^^^^^
This may sound like a dumb question to those in the know, but why can't you
turn the parts about .0006 under, and then heat treat? Would it be a
surface finish problem, or distortion or something I haven't thought of?
Just curious.
