Turning machine

A turning machine, comprising a spindle box;

• a workpiece spindle rotatably supported in said spindle box and having at its one end a clamping device for clamping rod- shaped workpieces;
• a tool holder arranged displaceably transversely to an axis of said workpiece spindle;
• a guiding bushing support;
• a workpiece guiding bushing rotatably supported in said guiding bushing support so that said guiding bushing is oriented coaxially with the axis of said workpiece spindle and exchangeably mounted in said guiding bushing support;
• displacing means for relatively displacing said workpiece spindle in said guiding bushing in the direction of the axis of said workpiece spindle, said workpiece spindle being sleeve-shaped and extending out of said spindle box over at least a length of the relative movement, and said workpiece guiding bushing being exchangeable by said workpiece spindle guiding bushing for receiving said sleeve-shaped workpiece spindle so that said workpiece guiding bushing and said workpiece spindle guiding bushing may be selectively used to support the workpiece and said workpiece spindle respectively.
