Abstract: A lathe exhibits a vertically positioned, motor-driven work spindle on whose lower end are positioned workpiece clamps, an initial compound slide system (19) by means of which the work spindle can move vertically in the Z1 direction and horizontally in the X1 direction, at least one initial stationary tool holder (22), and at least one second tool holder (46) which can execute an advancing action in at least one direction during the machining process. The advancing movement of the second tool holder (46) is independent of the control of the first compound slide system (19). The second tool holder (46) can be moved in controlled fashion along two axes by a second compound slide system (28, 30, 32, 34).

Abstract: A machine tool, such a lathe, is described that includes a machine base and four base columns supporting a horizontal roof-shaped upper section. Horizontally guided Y-carriages and Z-carriages are suspended from an underside of the upper section. A horizontal working spindle is suspended from the Z-carriages. An X-carriage is arranged and vertically guided on the lower section of the machine stand.
