Abstract:
(EN) Provided is a surface coated cutting tool in which a hard coating layer exhibits excellent chipping resistance and wear resistance. A surface coated cutting tool is configured such that: a TiAlN layer expressed by the composition formula (Ti1-xAlx)N is formed as the outermost layer of a hard coating layer; the average content ratio of Al xavg (atomic ratio) satisfies 0.70 ≤ xavg ≤ 0.90; the TiAlN layer is formed from crystal grain with a columnar structure having primarily a cubic structure; and the TiAlN layer surface of a rake face and a cutting ridge is smoothed by way of performing a blast treatment at an angle of incidence of 30 to 60 degrees with respect to a line normal to the rake face so that the surface roughness Ra of the outermost layer of the cutting ridge is 0.25 µm or less and the surface roughness Ra of the outermost layer of the rake face is 0.30 µm or less.
(FR) L'invention concerne un outil de coupe revêtu en surface dans lequel une couche de revêtement dur présente une excellente résistance à l'usure et à l'écaillage. Un outil de coupe revêtu en surface est configuré de telle façon que: une couche de TiAlN exprimée par la formule de composition (Ti1-xAlx)N est formée en tant que couche extérieure extrême d'une couche de revêtement dur; le rapport moyen de teneur en Al xavg (rapport atomique) satisfait 0,70 ≤ xavg ≤ 0,90; la couche de TiAlN est formée de grains cristallins à structure en colonne présentant principalement une structure cubique; et la surface de couche de TiAlN d'une face d'attaque et d'une arête de coupe est lissée en réalisant un traitement de grenaillage suivant un angle d'incidence de 30 à 60 degrés par rapport à une droite normale à la face d'attaque de telle façon que la rugosité de surface Ra de la couche extérieure extrême de l'arête de coupe soit d'au plus 0,25 µm et que la rugosité de surface Ra de la couche extérieure extrême de la face d'attaque soit d'au plus 0,30 µm.
(JA) 硬質被覆層がすぐれた耐チッピング性と耐摩耗性を発揮する表面被覆切削工具を提供する。 硬質被覆層の最外層として、組成式:(Ti1-xAl)Nで表されるTiAlN層が形成され、Alの平均含有割合xavg(原子比)は0.70≦xavg≦0.90を満足し、TiAlN層は立方晶構造を主体とする柱状組織の結晶粒から構成され、すくい面および切れ刃稜線のTiAlN層表面は、すくい面の法線に対して30~60度の投射角度でブラスト処理を施されることにより、切れ刃稜線の最外層の面粗さRaが0.25μm以下およびすくい面の最外層の面粗さRaが0.30μm以下となるように平滑化されている表面被覆切削工具。
