The invention relates to a coordinate measuring machine (40) comprising a movable cross beam (6), on which a further movable part (7) of the coordinate measuring machine (40) is guided in a movable manner, wherein • a measuring sensor (9) for measuring coordinates of a workpiece is or may be fastened to the further movable part (7), • the cross beam (6) is supported on a base (4) of the coordinate measuring machine by way of a first support (2) and a second support (10; 19) spaced apart from the first support (2), • the cross beam (6) has linear mobility in a linear movement direction relative to the base (4), • the second support (19) has a rotary joint (50) facilitating a rotation about an axis of rotation extending across the linear movement direction such that, in the case of a rotation about the axis of rotation, a first part (33) of the rotary joint (50), which is securely connected to the cross beam (6), is moved relative to a second part (31) of the rotary joint (50) and the second part (31) of the rotary joint (15) and/or a part (53) of the second support (19) connected to the second part (31) of the rotary joint (50) is, in the process, also moved relative to the first part (33) in the linear movement direction, a part of the second support (19) movably mounted in the linear movement direction, said part being the second part of the rotary joint or the part (41) of the second support (19) connected to the second part (31) of the rotary joint (50) in a secure or movable manner, being movably mounted relative to the base (4) in the linear movement direction by way of a movement bearing. |
