作機械における工具の切換え装置。 A cutting machine tool equipped with a milling cutter and a drill on the spindle head, the milling cutter is attached to the tip of the spindle head via a milling cutter holder, and the drill is attached coaxially to the milling cutter via the drill holder. The drill holder is inserted so as to be slidable along the axial direction, and the drill holder is displaced between a processing position where the drill protrudes from the cutting surface of the milling cutter and a retracted position where the drill is recessed from the cutting surface. A tool changeover device for a cutting machine tool, characterized in that the device is connected to a hydraulic circuit for the purpose.
