PCBN COMPACT FOR MACHINING OF FERROUS ALLOYS
The present application is a new improvement in the fine-grained cubic Boron Nitride sintered compact which may be employed to manufacture a cutting tool. The compact contains at least 80 vol % cBN and is sintered under HPHT conditions. The invention has lower levels of unreacted cobalt in the final sintered material than conventions materials. The invention has proved beneficial in the machiningof ferrous metal alloys such as sintered metal alloys.
本发明是可用于制造切削工具的细晶粒立方氮化硼烧结复合片的新改进。该复合片包含至少80体积％的cBN，并在HPHT条件下烧结。与常规材料相比，本发明在最终的烧结材料中具有较低水平的未反应钴。已证实本发明在烧结金属合金等铁金属合金的加工中是有益的。
