ABSTRACT:
The apparatus includes a frame, a plate coupled to a shaft for making the piece to be checked rotate with respect to the frame and a reference plate resting on the piece for defining a mechanical reference for the checking of the piece. A supporting device couples the reference plate to the frame and permits rotation of the reference plate together with the piece. Measuring heads, fixed to the frame, include feeler elements which contact - without any sliding motion - the supporting device, for indirectly detecting the position of the mechanical reference during the piece rotation.
