A coordinate measuring machine to determine the coordinates of a number of points on the surface of a measured object, includes a support beam, supporting a measuring head over the surface of a support table that supports the test object. The measuring machine is constructed from separately manufactured units, which include at least a support beam, a measurement trolley and a measurement head. The support beam supports the measurement trolley, which is displaceable along the support beam. The measurement trolley in turn supports the measurement head. The beam, head and trolley are individually calibrated, and the trolley includes both mechanical and electrical attachment points for the head and the beam, where the mechanical attachment points are designed such that no geometric deformation can take place when these units are joined together such that the units, which have been individually manufactured, can be simply joined to the coordinate measuring machine.
