Title:
硬質皮膜切削工具
Document Type and Number:
Japanese Patent JP7227472
Kind Code:
B2
Abstract:
To provide a cutting tool which exhibits excellent deposition resistance and peeling resistance even when used for high-speed cutting of a material, which has low thermal conductivity, high hardness, and high toughness, such as a titanium alloy, and nickel alloy, and exhibits excellent cutting performance for long-term use.SOLUTION: A surface coated cutting tool has at least a hard coat layer of which an average layer thickness is 0.5-10.0 μm on a surface of a tool base. A WTifilm (x is 0.01≤x≤0.30 in an atomic ratio) having an average thickness of 5-500 nm is formed on a side of the hard coating film layer of an interface between the surface of the tool base and the hard coat layer.SELECTED DRAWING: Figure 1
