    摘要: A machine tool, in particular turning machine, having a machine frame (1), having a first working spindle (21) which is arranged on a spindle carrier side of the machine frame (1) and which serves for holding a first workpiece (W1), having a second working spindle (22) which faces toward the first working spindle (21) and which is arranged on a spindle carrier side of the machine frame (1) and which serves for holding a second workpiece (W2), wherein the spindle axis of the second working spindle (22) is aligned parallel, in particular coaxially, with respect to the spindle axis of the first working spindle (21), and having two movable tool carrier carriages (51) and (52) on which in each case one tool-carrying tool carrier (61) and (62) is arranged. Between the working spindles (21) and (22), there is provided a tool carrier (62) which is movable transversely with respect to the spindle axes, which is in the form of a tool revolver and the revolver axis of which is aligned transversely with respect to the spindle axes.

    摘要: A machine tool (1) has a pair of guide rails (27) and a pair of upper and lower ball screws (28, 29). No forces are transferred between a beam (19) of a double column frame (7) and a movable unit (8). The guide rails (27) are spaced from each other and disposed on a bed (17), and the movable unit (8) is horizontally movably supported on the guide rails (27). The upper and lower ball screws (28, 29) are mounted respectively on upper and lower portions of the double column frame (7) for moving the movable unit (8) horizontally. Even when the beam (19) is deformed by flexing downwardly by gravity, the movable unit (8) moves stably and smoothly at a high speed to machine a workpiece highly accurately without being adversely affected by the deformation of the beam (19).
