there are stepper motors with a screw drive available that can (with appropriate driver circuits) be accurate to less than 1/10th of a millimeter acuraccy repeatable
I built a winding machine for my old boss that was accurate to 99% to .1 of a millimeter for winding coils- it wouldn't be that hard to use a thread driven stepper motor to place a traverser
(it wouldnt be that hard to accurately position turntables either- a 256 step direct drive stepper motor should be way more accurate than ness- all it would take is the controlling electronics to do it...)
