Abstract:
Machine tool comprising:a machine frame;at least one means for receiving a workpiece, said receiving means being rotatable about a workpiece axis and adapted to be fixed in a defined rotary position;a workpiece being accommodated in said receiving means for being machined;a tool carrier arrangement comprising a tool spindle for receiving a tool driven for rotation about a tool spindle axis, said tool being movable transversely to the workpiece axis and in the direction of the workpiece axis by means of a control and, in addition, being alignable such that the tool spindle axis is located in planes intersecting the workpiece axis and forming with this workpiece axis an angle in the range of approximately 0.degree. to approximately 90.degree.;said tool carrier arrangement comprising a tool spindle carrier pivotable about a pivot axis in relation to a bearing housing and adapted to be fixed on the bearing housing in at least one machining position;said pivot axis and said tool spindle axis of said tool spindle carrier in a machining position being adapted to define a plane extending parallel to said workpiece axis;said tool spindle carrier extending only on one side of the pivot axis in an angular range of less than 180.degree. around the pivot axis and away from the pivot axis and said tool spindle being arranged on the tool spindle carrier such that its tool spindle axis is in a position non-coaxial to the pivot axis.
