measurements to 10 millionths of an inch

Anybody know of a calibration lab or testing facility that can make xyz
measurements of a small sample with a max dimension of about 2 inches.
Accurracy should be in the +-10 millionths of an inch range.

I ran a mitsubishi wire edm that had a 5th place button. I hit that thing
ten times and it moved a total of .0001 of an inch.
Go find a shop with one of those.

Those Mitsubishis are crude slagheaps compared to the best Japanese
machines- 10 nanometer resolution! (that's less than half a
micro-inch).

Anyway, there's a lab in Switzerland that's supposed to be about the
best around.

On a related note, to show how far one can go with off-the-shelf
gages, you might be interested in a 0.1 micrometer micrometer. g:

That's about 4 microinches. Not bad. Just don't breathe when you use
it. d8-)
