    摘要： A cutting edge of a cutting tool is made of a polycrystalline hard sintered material containing at lest 20 vol % of CBN. A radius of curvature in cross section of a ridge of the cutting edge is between 5 &mgr;m and 30 &mgr;m. A flank and a rake face or negative land of the cutting tool are smoothly continued from the radius of curvature in cross section. The surface roughness of the ridge of the cutting edge is from 0.1 &mgr;m to 1.0 &mgr;m as an average roughness (Rz) of a ten point system.

    摘要： A metal cutting insert that is primarily intended for turning operations includes an upper surface, a lower surface substantially parallel with said upper surface, and at least three side surfaces extending between said upper and lower surfaces. A transition between two adjacent side surfaces forms a rounded nose radius surface at a cutting insert corner. The cutting insert includes a peripheral land bridging the upper and side surfaces at least at the corner portion at a chamfer angle. An intersection of the land and the nose radius surface forms a nose cutting edge. The nose cutting edge is defined by at least one radius. The cuffing corner includes at least one curved wiper edge. The chamfer angle in a cross-section at the nose cutting edge is larger than the chamfer angle in a cross-section a distance away from the nose cutting edge.

    摘要： A cutting tool is provided which comprises a curved cutting edge at a nose, a pair of straight cutting edges between which the nose is located, and a chamfer extending along the curved cutting edge and the straight cutting edges so as to form a curved ridge at a junction of a portion of the chamfer extending along the curved cutting edge and a tool face. A portion of the chamfer increases in width from a junction of the curved cutting edge and each of the straight cutting edges to a midpoint of the curved cutting edge when observed in plan.

    摘要： A method for manufacturing a cubic boron nitride cutting tool including a base metal and sintered cubic boron nitride compact at a corner portion of the base metal, capable of improving the accuracy of the center height and reducing the angle of inclination or width of a negative rake face; and the cubic boron nitride cutting tool. The method includes grinding the compact by pressing it against an end face of a grindstone of a grinder to form flank and rake faces on the compact while the base metal of the cutting tool is held by a chuck of the grinder, so that the compact is substantially ground. The rake face is formed to be recessed from a top face of the base metal or only a portion of the compact that protrudes from a base-metal rake face is ground while the tool is continuously held by the chuck.

    摘要： A cutting tool including an insert and a holder to which the insert is secured. The insert has a rod with a substantially circular transverse cross-section. The insert includes a shank portion and a cutting edge portion. The cutting edge portion is located at an end portion continuous with the shank portion. In the cutting edge portion, one end of a cutting edge ridge protrudes toward the periphery of the rod. When the insert is secured to the holder, the cutting edge ridge has a negative radial rake angle.
