In a combined working machine, a positional relationship between a machining position of a workpiece and a tool can be determined to an optional value by a combination of a slide amount of a carriage along a slant surface, a slide amount of a tool post along another slant surface, a pivot amount of a turret, and a rotational amount of a chuck of a headstock. That is, the tool of the tool post can be brought into contact with the workpiece from a slant direction, and a combined working including cutting by a cutting tool and drilling in a slant direction by a drill can be performed. Further, the tool of the tool post can be moved to the desired machining position of the workpiece from the slant direction, and thus the moving amount of the tool post in a vertical direction can be reduced to lower a height of a machine tool and to give stabilization thereto.
In a combined working machine for machining a workpiece held by a chuck rotatably and detachably mounted on a headstock by bringing a tool into contact with the workpiece, the improvement comprising a mechanism for bringing the tool into contact with the workpiece, said mechanism comprising:
