This post pertains to lathe thread chasing, but is relavent to all
thread creation.

I recently had to chase my first threads on a cnc lathe. Ive done it a
million times on a manual, but not on a cnc.
I was hardcutting threads on 58rc stainless

Start over junior.
There ain't no SS that hard.There is to much chrome in it as well as
tungsten.
SS is about as hard as H-13, another tool steel you are ignorant of.

S-7 maybe, it's properly hardened and tempered to 57 RC, but not
stainless.

Also, you haven't done anything a million times.
Well, maybe make excuses but that doesn't count.
