Steve,
I saw this too- never seen anything like this before. It's really quite
amazing to me, and been around since
1940s, and somehow, I've never seen it before?
I don't think this would work as a machine tool leadscrew. The inevitable
chips or dust would make it slip,
losing position accuracy- so would cutting oil, according to article. And
as soon as it takes a significant
cutting load, same there.
This is seriously amazing stuff though- I think this would make a very
simple and accurate toolmaker's microscope
or manual CMM possible for high end metrology work, where no machining is
being done.
I can't wait to read up on these more. Really cool find!

I wouldn't trust that to not slip.
