ABSTRACT:
A hollow shaft 12 measurement machine 10 which comprises a measurement table 11, a coordinate measurement machine 14, a rotatable hydraulic chuck 16, a movable/rotatable center 18 and a bore gauge 20. The movable/rotatable center allows direct movement of a gauge head 24 within the hollow shaft in order to ascertain the internal shaft measurements. The shaft is held accurately by the rotatable center 18 and by a contractable spline insert of the hydraulic chuck 16 so that the shaft's precise centerline axis can be determined.
