You aren’t going to hit that tolerance consistently on an assembly line no matter how much you pay. Can be done by a skilled machinist, but there are too many dynamical variables in an assembly line environment, like the previously mentioned thermal expansion.
I guess they could do like Nissan did with the GTR’s engine: climate controlled assembly bay, temperature check on the parts etc…
But I mean, they did it only for the engine which is relatively small

For reference, in working with parts that interface directly with optical components about the tightest I’m ever comfortable specifying at production volumes is 0.05mm and that is for very specific dimensions and not entire parts yet he is demanding 5 times lower tolerances here.
