Abstract

A cutting tool insert for machining by chip removal includes a body of polycrystalline cubic boron nitride compact (PCBN), either as a solid insert or attached to a backing body, onto which a hard and wear resistant PVD coating is deposited. The coating includes a polycrystalline nanolaminated structure of alternating A and B layers, where layer A is (Ti,Al,Me1)N and Me1 is one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table, layer B is (Ti,Si,Me2)N and Me2 is one or more of the metal elements from group 3, 4, 5 or 6 in the periodic table including Al with a thickness between 0.5 and 10 μm. The insert is particularly useful in metal cutting applications generating high temperatures, e.g., high speed machining of steels, cast irons, super alloys and hardened steels.
