As Jon says.

I am aware of one manufacturer offering a machine that claims higher
accuracies. They are Mazak, supposidely one of the best, if not the best,
machine tool manufacturer in the world.

The product is called Nanoturn and it's a lathe that is designed for
submicron accuracies. I believe the role of the lathe is in optical work,
making laser mirror for instance.

The ball screws of the machine have coolant flowing through their cores.

Looks like a fearsomely pricey piece of gear!
