A co-ordinate measuring machine (1, 30, 31, 32) comprising a bed (2) provided with a horizontal measuring surface, a unit (3) that is mobile along guides (10, 11) carried by the bed (2) itself, an annular structure (13) extending along a perimetral area (12, 35, 38) of the bed (2) and constrained thereto by statically determinate means of constraint (20, 21, 22), and a plurality of displacement sensors (S1-S8; S11-S16) set between the annular structure (13) and one between the bed (2) and the mobile unit (3) for detecting relative displacements with respect to an initial reference condition.
