ABSTRACT:
A precision positioning stage assembly, comprising a movable stage, a drive screw having it axis parallel to the direction of movement of the stage, a follower threadably engaged with the drive screw, and a linear guide rail for supporting one side of the stage. The linear guide rail has its axis parallel to the direction of movement of the stage. A drive member is secured to the stage which has a pair of oppositely disposed contact surfaces spaced apart a predetermined distance. A torque member is secured to the follower, the torque member having a drive section for placement between the contact surfaces and moving the stage along the guide rail. The drive section and the contact surfaces have a configuration so as to provide substantially point contact therebetween.
