    摘要: A method for making a super-hard construction comprising a first structure comprising a first material joined to a second structure comprising a second material, in which the coefficient of thermal expansion (CTE) and Young's moduli of the materials of each material are substantially different from each other. The method includes forming an assembly comprising the first material, the second material and a binder material arranged to be capable of bonding the first and second materials together, the binder material comprising metal; subjecting the assembly to a sufficiently high temperature for the binder material to be in the liquid state and to a first pressure at which the super-hard material is thermodynamically stable; reducing the pressure to a second pressure at which the super-hard material is thermodynamically stable, the temperature being maintained sufficiently high to maintain the binder material in the liquid state; reducing the temperature to solidify the binder material; and reducing the pressure and the temperature to an ambient condition to provide the super-hard construction.

    摘要: A cutter comprises a superhard construction, the cutter having a cutting edge defined by a rake face, and a flank extending therefrom. The cutter also has first and second regions, the first region abutting the second region along a boundary, the first region having a different material composition from the second region. At least the second region comprises superhard material, the material of the first region has a different coefficient of thermal expansion (CTE) from the material of the second region. The second region extends around the peripheral edge of the first region defined by the boundary to form a collar therearound, the first region and/or the second region extending to and/or forming at least a part of the rake face.

    摘要: A method of producing a tool insert which comprises a central metal portion having edge regions of superabrasive material bonded thereto and presenting cutting edges or points for the tool insert is disclosed. A body (50) having major surfaces on each of opposite sides thereof, each having spaced strips (64) of superabrasive material, typically abrasive compact such as PCBN or PCD, for example, separated by a metal region or regions, such as cemented carbide, is provided. Each superabrasive strip of one major surface is arranged in register with a superabrasive strip of the opposite major surface. Alternatively, each superabrasive strip extends from one major surface to the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in the respective superabrasive strips to produce the tool insert.

    摘要: A method of producing a tool insert having superabrasive cutting points or edges is disclosed. A body (10) of a hard metal having major surfaces (12, 14) on each of opposite sides thereof, such as a cemented carbide disc, is provided. Each major surface of the body has an array of pockets (12) filled with a superabrasive material, typically an abrasive compact such as PCBN or PCD, for example. A pocket of one major surface is arranged to be in register with a pocket of the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in respective superabrasive filled pockets to produce the tool insert. The severing of the body is carried out in such a manner as to expose the superabrasive material to form a cutting tip or edge in the tool insert.
