Motion mechanism for machine tools, and machine tool with such a motion mechanism. A drive assembly installed on machine tools includes at least one drive unit (18, 25) and, at least one motion guide (6,7) associated with the drive unit (18, 25). The drive unit (18, 25) includes at least one toothed rack (16, 23) and, meshing therewith, at least one drive pinion (17, 24). Components of the motion guide (6, 7) include at least one support structure (8, 3) as well as multiple guide units (10, 21) positioned along the support structure (8, 3) and jointly movably by a drive unit (18, 25). The toothed rack (16, 23) encompasses toothed segments (15, 22) that are at least partially integrated in at least part of the guide units (10, 21), and the guide units concerned (10, 21) are kept in alignment relative to one another so as to form the toothed rack (16, 23).
