ABSTRACT:
Complex machining such as lathe machining and milling including non-circular machining is effected by a single machine tool effectively and highly accurately.
The machine tool comprises a spindle stock having the C-axis control function, a carriage which can be moved and positioned in a direction of the axis of a main spindle, and two tool rests installed on the carriage. Lathe machining and milling are performed by the first tool rest, and non-circular machining is performed by the second tool rest. A tailstock can be also moved in the direction of the main spindle axis, and positioning of the movable members is controlled by an NC device. A force for supporting a workpiece is controlled by a chuck and a tailstock spindle in response to an M function command.
