Why Ball Screw Accuracy Matters. The ball screw assembly moves the cutter along the part being milled, transforming the power of the motor into cutting force. Because the ball screw is what moves the spindle, accuracy in its operation clearly affects accuracy in the final part. Ball screws are used because they allow closer tolerances than ...
