Abstract
A mechanical drive linkage for a blind spline broaching machine wherein a rotary motion provided by a servo driven helical ball or roller screw is converted to a linear reciprocal motion of a ram through the use of a kite link and a pivot link that as a part of their motion communicate with guide tracks in order to prevent side loads from being applied to the ball screw, its carriage, or the ram of the blind spline broaching machine.
