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： A double-sided cutting insert for milling which has eight main cutting edges and eight wiper edges. The cutting insert includes top and bottom faces and four side faces. Each side face includes first and second sub-faces inclined with respect to each other. The first sub-face has a main cutting edge adjacent to the top face and a wiper edge adjacent to the bottom face. The second sub-face has a wiper edge adjacent to the top face and a main cutting edge adjacent to the bottom face. The wiper edge of the second sub-face is inclined inwardly relative to the cutting insert with respect to the main cutting edge of the first sub-face. The wiper edge of the first sub-face is inclined inwardly relative to the cutting insert with respect to the main cutting edge of the second sub-face.

摘要： An assembly includes a double-sided indexable cutting insert and a reinforcing part. The assembly can be used to process metallic materials and the like. The polygonal, double-sided indexable cutting insert of the present invention has a plurality of convex portions at each corner portion. The level of the convex portions is lower than that of the corner cutting edges. Further, the reinforcing part of the present invention has flat portions that come into contact with the convex portions of the cutting insert at each corner portion. When the cutting insert and the reinforcing part are assembled together, the flat portions of the reinforcing part contact at least three convex portions of the cutting insert.

摘要： A hexahedral-shaped cutting insert has a concavely curved upper surface, a lower surface, a plurality of side surfaces connecting the two, and a central hole passing through the upper and lower surfaces. Cutting edges are formed at intersections between the upper surface and the side surfaces, and corner cutting edge portions are formed at borders of two adjacent cutting edges. Cutting edge height is largest at corner cutting edge portions and smallest in the middle portions. In an inward direction of the insert from a cutting edge, the upper surface has a land portion, a downward inclined surface, a bottom surface, and a seating surface portion. A plurality of semispherical protrusions are formed on border portions between the downward inclined surface and the bottom surface, and at least one corner cutting edge portion has a corner bottom surface surrounded by an outwardly facing arcuate protrusion connecting two adjacent semispherical protrusions.

摘要： A cutting insert is configured for shoulder milling cutting. The insert has a pair rectangular end surfaces which face away from each other, and pairs of first side surfaces and second side surfaces connecting the end surfaces. First cutting edges and second cutting edges in the first side surface are diagonally symmetrical with respect to a first imaginary median plane, which transverses the middles of both the first side surfaces. The first cutting edges and the second cutting edges in the second side surface are diagonally symmetrical with respect to a second imaginary median plane, which transverses the middles of both the second side surfaces. The second cutting edge is offset toward the first median plane from the first cutting edge. The first cutting edge is offset toward the second median plane from the second cutting edge.

摘要： A hexahedral insert has top and bottom faces and two pairs of opposing side faces with main cutting edges formed on the borders of the top and bottom faces to the side faces and a screw hole passing through each central portion of the top and bottom faces. The top and bottom faces are flat planes parallel to each other; each of the side faces consecutively from top to bottom includes an upper land portion, an upper inwardly-inclined portion, a flat support surface, a lower inwardly-inclined portion, and a lower land portion. Each of two adjacent side faces has a corner surface therebetween which forms corner edges on the borders to the top and bottom faces. The cutting insert enhances the cutting power by reducing cutting resistance and prevents scratches on a machined surface.
