To understand how to calculate RPMs for lead screws and ball screws, let's go with an example. Consider a lead/ball screw with a 2 mm pitch. What it means is that for every one turn of the lead/ball screw the nut will move a distance of 2 mm linearly. Let's say you need a feed rate of 150 ipm, which is around 3810 mm per minute.
