な靭性が得られなくなるので好ましくない。The binder phase of the cermet cutting tool for high-speed milling of the present invention is made of Ni and Co. If the total amount is less than 5%, the toughness is remarkably insufficient. It is not preferable because the wear resistance is reduced. In addition, Ni / (Co + Ni) of the binder phase
When the weight ratio represented by is 0.5 or less, the Co amount becomes Ni.
It is not preferable because the amount becomes large with respect to the amount and the lattice constant of the binder phase becomes larger than 3.545 angstroms and the fracture resistance decreases. On the other hand, when the value of Ni / (Co + Ni) becomes 1.0, Co It is not preferable because the cutting tool does not have sufficient toughness.

た。As described above, when the lattice constant of the binder phase is larger than 3.545 angstroms, the stress relaxation ability is reduced, and thermal cracking is likely to occur during high speed milling, which shortens the tool life. However, on the other hand, the lattice constant of the binder phase containing Co cannot be less than the theoretical lattice constant of Ni. Therefore, the bonding phase of the cermet cutting tool for high speed milling of the present invention is:
It accounts for 5 to 30%, and its composition is 0.5 <Ni / (Co +
Ni) <1.0 and the lattice constant is 3.545-
It was defined to be in the range of 3.524 Angstroms.
【００１８】さらに、この発明の硬質分散相の成分組成
範囲を上記の如く限定した理由は以下の通りである。Further, the reason why the component composition range of the hard dispersed phase of the present invention is limited as described above is as follows.

量が２５％未満では切削工具として実用化できるだけの
耐摩耗性が得られず、一方、６０％を越えて含有させる
と熱クラックが発生しやすくなるので好ましくない。(A) Titanium Carbide Titanium carbide is a component that improves the wear resistance. If the amount is less than 25%, the wear resistance sufficient for practical use as a cutting tool cannot be obtained, while if it exceeds 60%. If it is included, thermal cracking tends to occur, which is not preferable.
【００２０】したがって、サーメット製切削工具に含ま
れる炭化チタンは２５〜６０％に定めた。Therefore, the titanium carbide content in the cermet cutting tool is set to 25 to 60%.

巣孔が生じやすくなり、耐摩耗性を低下させるところか
らその含有量を１５〜３０％に定めた。(B) Titanium Nitride Titanium nitride cannot achieve the toughness of the cutting tool if it is less than 15%, and conversely if it exceeds 30%, it becomes difficult to sinter and burrows easily occur. The content was set to 15 to 30% from the viewpoint of reducing the wear resistance.

化モリブデンの合計量は１０〜３５％に定めた。(C) Tungsten Carbide and Molybdenum Carbide If the total amount of these components is less than 10%, the fracture resistance becomes inferior, which is not preferable. On the other hand, if the total amount exceeds 30%, the wear resistance and welding resistance are low. This is not preferable because it deteriorates the property. Therefore, the total amount of tungsten carbide and molybdenum carbide is set to 10 to 35%.

No heat deformation resistance is obtained, and on the other hand, if the content exceeds 25%, the fracture resistance decreases, which is not preferable.
