Abstract
A machine tool which can avoid interference between a tool post body and a second headstock without increasing the size of a fixed bed or decreasing the structural support rigidity is disclosed. Specifically, a combined-machining lathe comprises a first headstock fixed on a fixed bed; at least one of a tailstock and a second headstock is movably disposed on the fixed bed so as to be movable along the fixed bed; and a tool post body for rotationally supporting a turret having a plurality of tools set thereon. The tool post body is movably disposed between the first headstock and the at least one of a tailstock and a second headstock. The turret is placed on one side of the tool post body that is closer to the at least one of a tailstock and a second headstock, and the first headstock has a recessed portion that is dimensioned to accommodate the tool post body therein.
