Re: Lead or Ball Screws (lathe Conversion) Yes, backlash is the big one, on a manual lathe you do the majority of cutting in one direction and you tend to pull out and move back in the same direction, on a CNC often the motion is both ways when cutting. Friction is another reason as Tweakie says and lastly ballscrews tend to be more accurate ...

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".

The IH reduction is 4:1 via pulleys and another 5:1 via the ballscrew, or 20:1. Tormach says their rapids speed is 65 ipm. Let's plug these numbers backwards and see what we get: 65 inches / 0.0001″ = 650,000 ten thouhs = 650,000 steps per minute. 650,000 steps per minute / 200 steps per revolution = 3250 rpm.
