    摘要： A method of making a cutter structure comprising super-hard material defining a rake face topology is provided. The method includes providing a pre-sinter assembly comprising a substrate body having a formation surface defining a topology complementary to the rake face topology, and an aggregation comprising a plurality of super-hard grains, the aggregation disposed adjacent the formation surface of the substrate body, the substrate body comprising a source of catalyst or binder material capable of promoting the sintering of the super-hard grains at a pressure and temperature at which the super-hard material is thermodynamically stable; subjecting the pre-sinter assembly to the pressure and temperature to provide a sintered polycrystalline super-hard structure joined to the formation surface of the substrate body at a first major boundary of the super-hard structure and having a second major boundary surface opposite the formation surface; removing the substrate body to expose the first major boundary of the super-hard structure defining the rake face topology. Cutter inserts and machine tools are also provided.

    摘要： A construction comprising a sintered polycrystalline super-hard layer having mutually opposite reinforced boundaries, each of which is bonded to a respective reinforcement structure, in which the super-hard layer comprises polycrystalline diamond (PCD) material or polycrystalline cubic boron nitride (PCBN) material. The construction will be configured such that the equivalent circle diameter of each reinforced boundary is at least ten times the mean thickness of the super-hard layer between them. The reinforcement structures will be substantially free of material having a melting point of less than 2,000 degrees Celsius, at least adjacent the reinforced boundaries.
