    摘要： In a pilot hole of a workpiece made of a difficult-to-cut cast iron, a cutting tool having a leading end to which a cutting insert is attached is inserted to cut the surface of the wall of the pilot hole. At this time, the cutting tool rotates about an axis (α) and also revolves about another axis (β), so that contouring is performed on the workpiece by the tool. The cutting insert is formed of a sintered body having a CBN content of not less than 85% by volume, and the cutting insert has a thermal conductivity of not less than 100 W/(mK).

    摘要： An indexable insert for milling includes a metal base made of cemented carbide, and a cutting edge consisting of a sintered CBN compact and a flat drag type cutting edge which are brazed to the metal base or bonded thereto by integral sintering. A subcutting edge angle (.beta.), a negative land angle (.theta.) and a negative land width (L) are set at 30.degree. to 60.degree., 30.degree. to 45.degree. and 0.05 to 0.40 mm respectively, while the subcutting edge has a straight shape. Due to this structure, the indexable insert has excellent cutting performance particularly in face milling of parts which are made of gray cast iron, and the tool life can be extended.

    摘要： A solid carbide milling cutter has a substrate of hard metal and a multi-layer coating deposited at least to surface regions that contact a workpiece during a milling operation. The multi-layer coating includes a single-layer or a multi-layer functional layer deposited directly on the substrate surface and a single-layer or a multi-layer covering layer deposited on the functional layer. The functional layer has one or more layers of TixAl1-xN with 0.3≦x≦0.55. The covering layer has one or more layers of ZrN. The functional layer and the covering layer are deposited by HIPIMS, wherein during the deposition of the functional layer power pulses are applied to each sputtering target consisting of material to be deposited, which power pulses transfer an amount of energy to each sputtering target that exceeds a maximum power density in the pulse of ≧500 W/cm2.

    摘要： A milling cutter is composed of a tool body having an approximately cylindrical or disk-like shape and a plurality of edge portions provided on at least an outer peripheral portion of one end of the tool body at predetermined intervals along a circumferential direction. The edge portion has a major cutting edge and a minor cutting edge that perform an operation of cutting a workpiece, the major cutting edge is positioned outside the minor cutting edge in a radial direction, and the minor cutting edge has a cutting edge angle that is an angle with respect to a plane orthogonal to a center axis of the tool body and set so as to be an elevation angle open outward in the radial direction. When surface machining is performed on a workpiece with the milling cutter, a high degree of machined surface accuracy equivalent to that obtained by grinding is obtained.
