Anti Backlash Ball Screwws. While the use of ball screws for cnc is primarily about eliminating backlash, there are other reasons why they're the premier way of driving motion in CNC machines. For example, ball screws are very efficient and offer very little friction or wear. But, we will start with backlash and ball screws.
