I would assume that any decent robotics hardware R&D facility has at least a small machine shop with a mill and a lathe of some sort.
Waiting for a bidding process when you're in the middle of iterating, or if a particular part just broke, would get old very quickly!
Academics in a university setting may not have this if they're mostly into the software side; for the hardware side, it's typically part of the mechanical engineering programs which typically have nice machine shops :-)
