    摘要： Super hard composite material for tools, comprising a substrate of CBN sintered body containing more than 20% by volume of cubic boron nitride (CBN), improved in strength of base material, wear-resistance, hardness at high temperatures and acid-resistance usable in cutting work of steels which are difficult to be machined. The substrate (2) has a laminated film (1) consisting of super thin films (a) and (b) each deposited alternatively on the substrate (2), the super thin film (a) being made of nitride and/or carbide of at least one element selected from a group comprising IVa group elements, Va group elements, VIa group elements, Al and B and possessing a crystal structure of cubic system and metallic bond property, the super thin film (b) being made of at least one compound possessing a crystal structure other than cubic system and covalent bond property under equilibrium condition at ambient temperature and pressure, each unit layer of the super thin films (a) and (b) having a thickness of 0.2 nm to 20 nm, and the laminated film (1) on the whole possessing a crystal structure of cubic system.

    摘要： A cutting tool having excellent chip treatability and adhesion resistance is provided. The cutting tool includes a hard sintered body in at least a cutting edge and has a rake face and a flank face. The rake face has a chip breaker in a protruded or uneven shape. The hard sintered body contains at least 20% by volume of cubic boron nitride. A region of not more than 20 μm from a surface of the hard sintered body on the rake face side includes A-structures made of cubic boron nitride and B-structures made of at least one selected from the group consisting of hexagonal boron nitride, amorphous boron nitride, and boron oxide. The volume ratio of the B-structures to the sum of the A-structures and B-structures, B/(A+B), is not less than 5% by volume and not more than 90% by volume.
