Zusammenfassung:	A coordinate measuring machine (1) has a coordinate measuring machine body (2) and a controller (3). The coordinate measuring machine body (2) has a probe (4) having a measurement piece and a drive mechanism (5) for driving the probe (4). The probe (4) has a drive unit (43) for driving the measurement piece. The controller (3) includes a first measuring unit (321) and a second measuring unit (322). The first measuring unit (321) measures a displacement of the measurement piece driven by the drive unit (43). The second measuring unit (322) measures a displacement of the probe (4). The measurement accuracy of the second measuring unit (322) is lower than the measurement accuracy of the first measuring unit (321).
