(a) Base frame (which is identical to the upper frame) and the two moving wedges (in yellow) that are connected with a precise and stiff guiding system, connected to both the bottom mineral cast frame and to the outer I-beam, where the counter wedges are assembled. The central bearing system that prevents erroneous longitudinal displacement can be seen in the middle (light blue). (b) Detail of the moving wedge (in yellow). This is driven by a servo motor (in black), fixed on a nut (in purple) and attached to the frame (on its bottom side). (c) Satellite roller screws used to drive the spindle. (d) Pre-loading of a satellite roller screw used to minimize the backlash.
