摘要
PROBLEM TO BE SOLVED: To provide a surface coated cemented carbide end mill with a hard coating layer showing superior heat radiation.;SOLUTION: The surface coated cemented carbide end mill comprises first thin layers and second thin layers alternately laminated on the surface of a tungsten carbide based carbide substrate with their individual average layer thicknesses being 0.01-0.1 μm and a hard coating layer physically deposited thereon with its total average layer thickness being 0.8-10 μm. The first thin layer is represented by composition formulae: [Ti1-XAlX]N and [Ti1-XAlX]C1-mNm, by constituting one of a Ti-Al composite nitride layer and a Ti-Al composite carbon-nitride layer of both of them, where X is 0.30-0.70, and m is 0.6-0.99 by an atomic ratio in measurement at a central portion in the direction of thickness with an auger spectroscopy, and the second thin layer is constructed by an aluminum nitride layer.;COPYRIGHT: (C)2002,JPO
