It's kind of sad how much knowledge is hidden inside companies.

(I'm assuming something like this was achieved decades ago in certain companies.)

It has. The Moore Special Tool Company makes diamond turning lathes much like this one. But replicating that precision on your own is still an immense achievement.

As Dan Gelbart once said: "Building your own lathe is an admirable ambition. Building one with micron accuracy is a terrible illness which, at my age, has no cure."
