Title (EN) CUTTING TOOL AND MANUFACTURING METHOD THEREOF
(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) In a cutting tool provided with a substrate, the substrate is a cemented carbide or cermet, the surface of the substrate includes a rake face, a flank face, and a cutting edge which connects the rake face and the flank face, and in the substrate, the oxygen concentration at a depth position 0.4 μm from the cutting edge is less than or equal to 1 at%.
(FR) Cette invention concerne un outil de coupe pourvu d'un substrat, le substrat étant un carbure cémenté ou un cermet, la surface du substrat comprenant une face de rabotage, une face de flanc, et un bord de coupe qui relie la face de rabotage et la face de flanc, et dans le substrat, la concentration en oxygène à une position de profondeur de 0,4 µm à partir du bord de coupe est inférieure ou égale à 1 % at.
(JA) 基材を備える切削工具であって、基材は、超硬合金またはサーメットであり、基材の表面は、すくい面と、逃げ面と、該すくい面および該逃げ面を繋ぐ刃先面とを含み、基材において、刃先面から0.4μmの深さ位置での酸素濃度が1原子%以下である。
