Title (EN) CUTTING TOOL AND METHOD FOR MANUFACTURING SAME
(FR) OUTIL DE COUPE ET SON PROCÉDÉ DE FABRICATION
(JA) 切削工具およびその製造方法
Abstract:
(EN) This cutting tool is provided with a base material, and a coating film covering the base material by being in contact with the base material. The base material is a cubic boron nitride sintered compact. The coating film is formed of a ceramic material. The amount of oxygen in the coating film is 0.040 mass% or less.
(FR) La présente invention concerne un outil de coupe comprenant un matériau de base et un film de revêtement qui recouvre le matériau de base en étant en contact avec le matériau de base. Le matériau de base est un corps compact fritté en nitrure de bore cubique. Le film de revêtement est formé d'un matériau en céramique. La quantité d'oxygène dans le film de revêtement est de 0,040 % en masse ou moins.
(JA) 切削工具は、基材と、基材に接して基材を被覆する被膜とを備える。基材は立方晶窒化硼素焼結体である。被膜はセラミックスである。被膜中の酸素量は、0.040質量%以下である。
