Claims

[Claims for Utility Model Registration] A concave tip pocket is formed on the outer periphery of the tip of the tool body, and a concave groove-shaped chip mounting seat is formed on the wall surface of the tip pocket facing the rotation direction, and the chip mounting seat is A throw-away chip in the form of a substantially rectangular plate whose lower surface, which is a seating surface, is in contact with the bottom surface of the chip, whose upper surface is a relief surface, and whose one side surface located between the upper surface and the lower surface is a rake surface. In a throw-away type face milling cutter that is removably attached to the throw-away tip, on two side surfaces adjacent to the rake surface of the throw-away tip, from the rake surface and the side opposite to the rake surface, respectively, to the central part thereof. one of the inner wall surfaces of the tip mounting seat that is inclined inwardly toward the throwaway chip to form two V-shaped inclined surfaces, and which faces these V-shaped side surfaces; an inclined wall surface that contacts the inclined surface on the chip mounting seat side of the side surface, and two surfaces that form a wedge between the other inner wall surface and the side surface opposite to this inner wall surface are formed on each of the above-mentioned side surfaces. A throw characterized in that a wedge member is provided on the inner wall surface and the sloped surface of the side surface on the side of the tip mounting seat, the wedge member being movable from the outer peripheral side of the tool body toward the bottom surface of the tip mounting seat. Away type front milling cutter.
