Title (EN) DIAMOND-COATED ROTATION CUTTING TOOL
(FR) OUTIL DE COUPE ROTATIF REVÊTU DE DIAMANT
(JA) ダイヤモンド被覆回転切削工具
Abstract:
(EN) The present invention makes it possible to prevent the occurrence of defects due to peeling or chipping, and obtain a smooth machined surface. A diamond coating includes a first diamond layer comprising fine diamond particles and a second diamond layer comprising large diamond particles. In a flank-side diamond coating, the average film thickness d2 is 3-25 μm inclusive, and has the first diamond layer formed on the obverse surface side and the second diamond layer formed on the tool base side. In a rake face-side diamond coating in the range of 50 μm or 1/10 of the tool diameter, whichever is smaller, from the tip of a base cutting blade part, the average film thickness d1 is in the range of 0-5.0 μm inclusive or 0 μm to less than d2, whichever is smaller. The boundary between the first diamond layer and the second diamond layer at an edge surface of the flank-side diamond coating is exposed on the base flank side in relation to the extension of a reference line linking the base cutting blade part and the center of rotation of the tool on the perpendicular cross-section of the base cutting blade part.
(FR) La présente invention permet d'empêcher l'apparition de défauts dus au pelage ou à l'écaillage et d'obtenir une surface usinée lisse. Un revêtement de diamant comprend une première couche de diamant comprenant de fines particules de diamant et une seconde couche de diamant comprenant de grandes particules de diamant. Dans un revêtement de diamant côté flanc, l'épaisseur de film moyenne d2 est de 3 à 25 µm inclus et a la première couche de diamant formée sur le côté de surface avers et la seconde couche de diamant formée sur le côté de base d'outil. Dans un revêtement de diamant côté face de coupe dans la plage de 50 µm ou 1/10 du diamètre d'outil, selon la taille la plus petite, à partir de la pointe d'une partie lame de coupe de base, l'épaisseur de film moyenne d1 est dans la plage de 0 à 5,0 µm inclus ou 0 µm à moins de d2, selon la taille la plus petite. La limite entre la première couche de diamant et la seconde couche de diamant au niveau d'une surface de bord du revêtement de diamant côté flanc est exposée sur le côté flanc de base par rapport à l'extension d'une ligne de référence reliant la partie lame de coupe de base et le centre de rotation de l'outil sur la section transversale perpendiculaire de la partie lame de coupe de base.
(JA) 剥離やチッピングによる欠陥の発生を防止でき、平滑な加工面を得る。 ダイヤモンド被膜は、微細なダイヤモンド粒子からなる第1ダイヤモンド層と、大きいダイヤモンド粒子からなる第2ダイヤモンド層とを含み、逃げ面側ダイヤモンド被膜は、平均膜厚d2が3μm以上25μm以下であり、表面側に第1ダイヤモンド層、工具基体側に第2ダイヤモンド層が形成されており、基体切れ刃部の先端から50μmまで又は工具直径の1/10までのいずれか小さい方の範囲のすくい面側ダイヤモンド被膜は平均膜厚d1が、0μm以上5.0μm以下又は0μm以上d2未満のいずれか小さい範囲であり、逃げ面側ダイヤモンド被膜の端面における第1ダイヤモンド層と第2ダイヤモンド層との境界部が、基体切れ刃部の垂直断面において工具回転中心と基体切れ刃部とを結ぶ基準線の延長線よりも基体逃げ面側で露出している。
