SURFACE-COATED CUTTING TOOL WITH EXCELLENT CHIPPING RESISTANCE AND WEAR RESISTANCE
이 표면 피복 절삭 공구에서는, 적어도 날끝이 cBN 소결체로 이루어지는 공구 기체 표면에, (AlTi)N 층 (단, 원자비로, 0.35 ≤ x ≤ 0.6) 으로 이루어지는 A 층과 (AlTiSi)N 층 (단, 원자비로, 0.35 ≤ y ≤ 0.6, 0.01 ≤ z ≤ 0.1) 으로 이루어지는 B 층을 적층 피복하고, A 층과 B 층의 층두께비 t/t는 2 이상 5 이하로 하고, 경질 피복층 전체로서의 X 선 회절 강도비 I(200)/I(111) 은 3 초과 12 이하로 하고, I(200) 의 피크의 반치폭은 0.3 이상 1.0 이하로 하고, 바람직하게는 A 층의 I(200)/I(111) 은 2 초과 10 이하, I(200) 의 피크의 반치폭은 0.3 ∼ 1.0 으로 하였다.
In a surface-coated cutting tool, an A layer made of an (Al 1-x Ti x )N layer (here, 0.35 ¤ x ¤ 0.6 by an atom ratio) and a B layer made of a (Al 1-y-z Ti y Si z )N layer (here, 0.35 ¤ y ¤ 0.6 and 0.01 ¤ z ¤ 0.1 by an atom ratio) are layered and coats a surface of a tool body in which at least a cutting edge is made of a cBN sintered body, a layer thickness ratio of the A layer and the B layer (t B /t A ) is set to be 2 to 5, an X-ray diffraction intensity ratio I(200)/I(111) as the entire hard coating layer is set to be more than 3 and 12 or less, a full width at half maximum of a peak of I(200) is 0.3 to 1.0, the I A (200)/I A (111) of the A layer is desirably set to be more than 2 and 10 or less, and a full width at half maximum of the peak of the I A (200) is 0.3 to 1.0.
