Because ball screws are a bearing system, they’ll need some type of lubrication to avoid metal-to-metal contact of the balls in the raceway. While the lubrication choice can be either oil or grease, it’s advisable to avoid solid additives (such as graphite) as they will clog the recirculation system.

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.
