Besides ground versus rolled, ball screws come in different accuracy grades that you should be aware of: C0 – 3um or 0.0001″ per 300 mm / 12″. C3 – 7um or 0.00027″ per 300 mm / 12″. C5 – 14um or 0.0005″ per 300 mm / 12″. This refers to how close the position will be after the screw has turned through 12″ of motion.

Therefore, material from the Y-Axis ballnut must be removed to provide adequate clearance for it to pass the jack screw.

Ball screws are required with a CNC mill. While CNC control is on the servo or stepper holds the screws tight all the time. In manual though the ball screws will move (creep) when not intended. The original acme screw has more hold on the non moving axis. So if you have ball screws you need to always tighten down the non moving axis.

The key to "ball-screw back-feed" is the screws co-efficient of friction and its helix angle which are functions of the screw pitch diameter and its lead. ie the larger the ball-screw pitch diameter and the smaller its lead the smaller its helix angle will be and the least likely it will be to "back-feed". justanengineer.
