acetal is very easy to machine i left the outside diameter at 1625 and using the lathe drilled a 0875 hole through the center i finished the hole to size with a boring bar the hole size for making a nut is the diameter of the screw less one thread depth in this case the screw was 1000 and a 10 tpi acme thread has a depth of 0.

there is an advantage with ball screws when they have no backlash and that is you can climb mill normally this is not possible with manual machines because the acme screws always have backlash or are to tight to move compfortably normally this is not possible with manual machines i disagree respectfully.

i have a clausing 8520 milling machine now currently taken apart for cleaning and restoration and i was giving some thought to seeing about maybe trying to add cnc to it at some point anyway in doing a little preliminary research it seems that ball screws work well for stepper motors but maybe not so well for manual cranking.

making a cnc milling machine requires a lot of metal working most people will use a manual milling machine to do the metal work i was lucky to have access to a cnc machining center so that is how i made my ballscrew mounts a ballscrew sometimes spelled ball screw is a type of linear actuator that translates rotary motion into linear motion.
