I stumbled across this website and the pics of the "pie jaw chucks". I did
a
little googling around and generally understand their benefits.

Do you machine the gripping bore to suit the work?

Why do the jaws in the pic have the radial profile rather than solid -
just
to save material & weight?


I think you are looking at soft jaws. Soft jaws are often used on cnc
lathes to hold
parts. The jaws are clamped on a ring to keep them from fully closing and
the profile of
the part is cut into them.

Cheers Wes, I neglected to post the link to the website (my apologies!).
Yeah they look like they might be soft jaws, but ones that provide more
support around the part.
