Calibration apparatus comprising a positional calibration means, and a machine tool assembly chuck configured to, in use, locate a machine tool assembly comprising a machine tool configured to be adjustably mounted on a machine tool mount. The positional calibration means and chuck are mounted on a common base relative to one another. The positional calibration means comprises a calibration headstock provided with a positional feature engagement means for cooperative engagement with a machine tool location feature provided on the machine tool. When the machine tool is adjusted on the machine tool mount relative to the positional calibration means, cooperative engagement of the positional feature engagement means and the machine tool location feature indicates the machine tool is aligned along a predetermined machine tool calibration axis.
