    摘要： The present invention discloses a cutting insert which can be mounted stably to the small- diametered cutter with a sufficient mounting surface and has a plurality of corner cutting edges. The cutting insert according to the present invention has a shape having an upper face and a lower face being opposite to each other, and two longitudinal side faces and two transversal side faces connecting the upper face and the lower face, with a through hole passing through each central part of the upper face and the lower face. The longitudinal side faces are opposite to each other and normal to the upper face and the lower face, and the transversal side faces are opposite to each other and normal to the upper face and the lower face. In addition, each of the upper face and the lower face is provided with two chip discharge grooves extended along both transversal side faces, and the two chip discharge grooves are inclined oppositely in the transverse direction so that each of the upper face and the lower face is provided with two corner cutting edges at diagonally opposite corners. Here, the longitudinal length of the cutting insert defined by the maximum length between the transversal side faces is longer than the transversal length defined by the maximum length between the longitudinal side faces.

    摘要： A rotary cutting tool for slotting and a cutting insert replaceably mounted to such a rotary cutting tool. The cutting insert is mounted to an insert pocket of a tool body of the rotary cutting tool and is pressed by an elastic pressure portion provided in the tool body. The cutting insert has an upper surface, a lower surface and four peripheral side surfaces. The top and lower surfaces have an inclined surface pressed by the elastic pressure portion. When the cutting insert is mounted to the insert pocket, the inclined surface of the upper surface is pressed by the elastic pressure portion. The inclined surface is inclined with respect to a cross section of the cutting insert such that the lower surface and two peripheral side surfaces of the cutting insert are contacted with the insert pocket by pressure of the elastic pressure portion.

    摘要： An indexable cutting insert for vertical and oblique machining. The cutting insert has top and bottom surfaces, first to fourth side surfaces extending between the top and bottom surfaces, and a screw hole passing through the top and bottom surfaces. The top surface has a mounting surface of a flat surface. The top and bottom surfaces are rotationally symmetric with each other. A cutting edge is formed at a junction between the top surface and the adjacent first and second side surfaces. A non-cutting edge is formed at a junction between the top surface and the adjacent third and fourth side surfaces. The first and second side surfaces form an acute angle with a plane extending from the mounting surface of the top surface. The third and fourth side surfaces form an obtuse angle with the plane extending from the mounting surface of the top surface.

    摘要： A cutting insert of the present invention has a top surface and a bottom surface having a parallelogram shape, and four side surfaces connecting the top and bottom surfaces. One or more primary cutting edges are formed at intersections between the top and bottom surfaces and two opposing side surfaces. Secondary cutting edges are formed at intersections between the top and bottom surfaces and two other opposing side surfaces. The primary cutting edge forms a first angle with respect to a median plane parallel to the top and bottom surfaces. The secondary cutting edge forms a second angle with respect to the median plane. The top and bottom surfaces have a mounting surface and a rack surface, wherein the rack surface extends inwardly from the cutting edge toward the median plane. The top and bottom surfaces of the cutting insert have mirror symmetry with respect to the median plane.

    摘要： A cutting insert of the present invention has a body, auxiliary cutting edges of a convex curve shape and main cutting edges. The body has a top surface, a bottom surface, side surfaces connecting the top and bottom surfaces, and corner surfaces connecting the adjacent side surfaces. The auxiliary cutting edges are formed at intersections between the top and bottom surfaces and the side surfaces. The main cutting edges are formed at intersections between the top and bottom surfaces and the corner surfaces. The main cutting edge in the top surface extends from an end of an adjacent auxiliary cutting edge to its center in a direction toward the bottom surface and from the center to an end of another adjacent auxiliary cutting edge in a direction away from the bottom surface.
