ABSTRACT:
A machine tool, in particular a long-bed machine tool, comprises a column (11) that can be displaced in at least a first axis (13), and at least one spindle (15) clamped rotatably at support points (22, 23) in the region of its two outer ends (20, 21). The spindle (15, 16) extends parallel to the first axis (13) and is joined to the column (11) in such a way that when the spindle (15) rotates, the column (11) is displaced in the first axis (13). A damping apparatus (28) acting on the spindle (15) between the support points (22, 23), which damps any vibrations of the spindle, is provided on the machine tool. The damping mechanism (28) is displaceable along the first axis (13) at least to some extent independently from the column (11).
