    Abstract: The present invention relates to a cutting tool insert, solid end mill, or drill, comprising a substrate and a coating. The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a cubic (Me,Si)X phase, where Me is one or more of the elements Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and Al, and X is one or more of the elements N, C, O or B. The ratio R = (at-% X)/(at-% Me) of the c-MeSiX phase is between 0.5 and 1.0 and X contains less than 30 at-% of O + B. This invention is particularly useful in metal machining applications where the chip thickness is small and the work material is hard e.g. copy milling using solid end mills, insert milling cutters or drilling of hardened steels.

    Abstract: The present invention relates to a cutting tool insert, solid end mill, or drill, comprising a substrate and a coating. The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a h-Me1Me2X phase, where Me 1 is one or more of the elements V, Cr, Nb, and Ta and Me2 is one or more of the elements Ti, Zr, Hf, Al, and Si and X is one or more of the elements N, C, O or B. The ratio R = (at-% X)/(at-% Me 1 + at-% Me2) of the h-Me1Me2X phase is between 0.5 and 1.0, preferably between 0.8 and 1.0 and X contains less than 30 at-% of O + B. This invention is particularly useful in metal cutting applications where the chip thickness is small and the work material is hard e.g. copy milling using solid end mills, insert milling cutters or drilling of hardened steels.

    Inventor： LARSSON TOMMY ,  JOHANSSON MATS

    Abstract: The present invention relates to a cutting tool insert comprising a body of a hard alloy of cemented carbide, cermet, ceramics, cubic boron nitride based material or high speed steel a hard and wear resistant coating, comprising one or several layers, at least one of which an (Al,Cr) 2 O 3 layer is applied. This invention is particularly useful for machining of cast iron. The coating, with a total thickness of 2-20 µm comprises one or several layers, at least one of which is an (Al,Cr) 2 O 3 layer with a thickness of 1-5 µm having a corundum phase crystalline structure and a composition (Al 1-y Cr y ) 2 O 3 with 0.4‰¤y‰¤0.6. The (Al,Cr) 2 O 3 layer is further characterized having a fiber texture with rotational symmetry in the direction of the coated surface normal with an inclination angle, Õ, of the basal planes relative to the coated surface normal or the inclination angle, Õ, for the highest peak in the pole plot with 40°
