How to machine a ball screw

[mitchejc]

I have not tried to machine ballskrew ends yet but on other hardened stuff I just put it in the lathe and grind the first bit off with a handheld angle grinder while its spinning so you don't get it out of round too far and then machine from there. Depending on how tough the steel on the inside is, you might get away with HSS tooling once you grinded away the chrome and thin case hardened layer.

This could be the perfect opportunity to build a toolpost grinder for your lathe ;-)
