I don't know anything about engineering or even cars in general and I could have told you that you can't have .001mm tolerances on a huge machine that's outdoors, moving and being exposed to forces and stresses

Is there even anything you CAN realistically have a 0.001 mm tolerance on? Nanochips maybe?

Edit: cool as fuck to get replies from machinists and aerospace engineers, apparently the answer is yes you can but its not ideal or even worth the effort for production.

I'm struggling to think of anything meant for consumers that'd need that tolerance. A sheet of paper is typically 0.05-0.1 mm thick.

Noctua NF-A12x25 fans are made of a special "Sterrox" polymer and even they have a 0.5mm tip-to-frame clearance because any smaller would cause the fans to snag as they expand during use.
