Cubic boron nitride-based very high pressure-sintered material for cutting tools |
摘要 |
A cubic boron nitride-based very high pressure-sintered material very excellent in both toughness and wear resistance and adapted to be employed in cutting tools for milling hard steels and like machining purposes. The very high pressure-sintered material consists essentially of: 1-20 percent at least one compound selected from the group consisting of titanium carbide and titanium carbo-nitride; 1-20 percent at least one compound selected from the group consisting of CoAl, NiAl, and (Co, Ni)Al; and 75-97 percent cubic boron nitride and inevitable impurities. The very high pressure-sintered material may further contain 1-10 percent at least one metal selected from the group consisting of cobalt and nickel.
