Machinig Ball Screws

CNC Crew:

I can not find the original message. Wasn't someone asking about
machining ends on ball screws recently? Trying to temper (heat & slow
cool) the ends in a lathe to make them easier to machine.

Anyway, I'm facing the same problem and am also looking for advice.

I understand hardened ball screws can be machined using carbide tooling.
I am planning to do this for a rough cut. I'm then planning to use a
tool post grinder for finishing. For those who've done this, does this
procedure make sense?

I have not used a tool post grinder but it seems like a good thing to
have around. I keep finding applications for shafts with ball bearings
fits which I find hard to machine without grinding. I'm about to start
construction of "A Lathe Tool Post Grinder for Serious Grinding" from
plans by D.E. Johson in the Jan/Feb & Mar/April 1999 Home Shop
Machinist. It uses a laminate router for the power source.

So, before I go off on a tangent, I thought I would ask the group for
comments on any of 1) genral process using carbide and tool post grinder
on ball screws, 2) use of tool post grinders & 3) if anyone has any
experience with these particular plans.

Thank you greatly. :-)
