    摘要： A cutting insert has an upper face and a lower face; a front side face portion and a back side face portion, the front and back side face portions connecting the upper face and the lower face; and a through-hole passing through the upper face and the lower face. A cutting edge is formed in the front side face portion, and the back side face portion is provided with a first inclined face and a second inclined face which are inclined forwardly at different angles, respectively, with respect to a plane normal to a rotational axis. The first inclined face is longer than the second inclined face so that the back side face portion has a non-symmetrical convex "V" shape.

    摘要： A cutting insert mountable in an insert pocket of a milling cutter and capable of effectively absorbing a radially outward force during high speed machining and high ramp machining. The cutting insert has a top surface, a bottom surface, peripheral surfaces extending between the top and bottom surfaces, a mounting hole extending through the top surface and the bottom surface, a protrusion portion protruding from the bottom surface, and a pair of lower inclined abutment surfaces formed at opposite edges of the bottom surface. The lower inclined abutment surfaces are inclined in opposite directions toward a pair of opposing peripheral surfaces, outwardly and upwardly relative to the protrusion portion. The protrusion portion extends across the mounting hole and has a lateral surface facing radially outwardly of the milling cutter. The lateral surface selectively contacts or does not contact the insert pocket depending on a revolution speed of the milling cutter.

    摘要： A polygonal cutting insert for right angle machining has opposed upper and lower surfaces, a peripheral side surface interconnecting the upper and lower surfaces and having curved first and fourth side surfaces and plane second and third side surfaces, and main and secondary cutting edges alternately formed along the outer peripheries of the upper and lower surfaces. The adjacent main and secondary cutting edges form a right angle therebetween. The first side surface adjoins the main cutting edge of the upper surface. The second side surface adjoins the secondary cutting edge of the lower surface. The third side surface adjoins the secondary cutting edge of the upper surface. The fourth side surface adjoins the main cutting edge of the lower surface. The cutting insert is mounted on a milling cutter at a positive axial rake angle.

    摘要： The present invention discloses a cutter device having a pocket formed on a body to receive an insert and a screw hole formed in proximity of the pocket to receive a screw, clamping the insert by a deformable gripping part which is displaced by the screw wherein: the insert has a hexahedral shape, and has parallel upper and lower surfaces and parallel opposing side surfaces, one opposing pair of the side surfaces being provided with grooves extending lengthwise, the other opposing pair of the side surfaces having cutting blades on the upper and lower edges, the pocket is formed by two side walls, a backside wall, and a bottom wall, and is open forwardly and upwardly, one side wall being provided with a guide protrusion extending lengthwise and fit complementarily to one of the grooves of the insert, the other side wall being a portion of the deformable gripping part and being provided with a guide protrusion extending lengthwise to fit complementarily with the other one of the grooves of the insert, the screw has a taper portion which has a diameter increasing toward the head end, and the deformable gripping part has a neck portion which is formed by a slot traversing the screw hole inclinedly and a lower edge of the other side wall of the pocket, and is elastically displaceable so that the distance between the guide protrusions is narrowed by pressing of the taper portion when the screw is tightened.
