People interested in this might also appreciate this small channel: a no-holds-barred 5 axis machine with expected sub-micron precision. I've learned a lot about what kind of components are available when budget is not an issue (I'll bet this machine will cost 100k by the time it's done). https://www.youtube.com/@kasramehraky9283

Those are the kind of CNC kept in isolated rooms, and covered in gold foil to reflect heat. No humans allowed during the measurement cycle.

		No, good thermal management with a chiller, active thermal compensation, and glass scales make um precision on that scale reasonable. 10-100x better? Sure, you’re getting into machines where the room to keep them happy is significantly more expensive that the machine…
