    摘要： A hard sintered body for tools is obtained by sintering under a superhigh pressure, a sinter powder mixture containing at least 20 percent by volume and not more than 70 percent by volume of cubic boron nitride powder and having a remainder formed of a binder powder mixture. The binder contains at least 2 percent by weight and not more than 20 percent by weight of Al and at least 2 percent by weight and not more than 20 percent by weight of W, and has a remainder formed of a Ti compound or compounds. The atomic ratio of Ti contained in the binder to a transition metal element or elements belonging to any of the groups IVa, Va and/or VIa of the periodic table including Ti is at least 2/3 and not more than 97/100. In the structure of the sintered body, cubic boron nitride crystals are bonded with each other through bonding phases formed by the binder. For forming the sintered body, at least one or more Ti compounds are selected from a group of TiN.sub.z, Ti(C,N).sub.z, TiC.sub.z, (Ti,M)N.sub.z, (Ti, M) (C,N).sub.z and (Ti,M)C.sub.z, wherein M represents a transition metal element or elements belonging to any one of the groups IVa, Va and/or VIa of the periodic table excluding Ti, and z is within the range of 0.1.ltoreq.z.ltoreq.0.40. Such a sintered body has an excellent crater wear resistance, so that it can be used for making tool inserts for high-speed cutting of steel or cast iron.

    摘要： A sintered body insert for cutting comprises an intermediate layer consisting of at least one of cemented carbide, a ferrous metal and a high melting point metal, and a first layer and a second layer, each consisting of hard sintered bodies containing cubic boron nitride or diamond, which are arranged on opposite sides respectively above and below with the intermediate layer therebetween. The first and second layers are bonded to the intermediate layer by sintering. The is so formed or configured that its front and rear surfaces define cutting faces. All noses and flanks involved in cutting are formed on the first layer and the second layer, while the centers of gravity of the cutting faces and of the overall insert are located at positions on or in the intermediate layer. Further, coating layers consisting of a nitride of an element belonging to the group 4a, 5a or 6a of the periodic table or other components are formed on the surfaces of the cutting faces and the flanks. With this structure, it is possible to provide a sintered body insert for cutting which is prolonged in life and excellent in economy such as the manufacturing cost.

    摘要： A hard sintered compact for tools is a sintered compact obtained by super-high pressure sintering of 45-75% by vol. of cubic boron nitride powder and the remaining proportion of binder powder. The binder includes 5-25% by wt. of Al and the remaining proportion of at least one species of compounds represented by (Hf.sub.1-z M.sub.z) C, where M denotes elements of IVa, Va and VIa groups in a periodic table except for Hf, and 0.ltoreq.z.ltoreq.0.3 is satisfied. Because of this composition, improvements are made in strength, wear resistance and heat resisting property of the binder, and a hard sintered compact for tools having excellent strength and excellent wear resistance can be obtained.
