Abstract
The invention relates to a compact containing crystals of cubic boron nitride and a binder containing at least one of the intermetallic compounds selected from the group consisting of Ti.sub.2 Cu, Ti, Cu, Ti.sub.2 Cu.sub.3, TiCu.sub.3, Zr.sub.2 Cu, ZrCu, Zr.sub.2 Cu.sub.3, and ZrCu.sub.3. A method for the production of this compact comprises the steps of forming a composition including crystals of cubic boron nitride and a binder containing at least one of the intermetallic compounds selected from the group consisting of Ti.sub.2 Cu, TiCu, Ti.sub.2 Cu.sub.3, TiCu.sub.3, Zr.sub.2 Cu, ZrCu, Zr.sub.2 Cu.sub.3, and ZrCu.sub.3, and subjecting the obtained composition of cubic boron nitride and the binder to a pressure within the range of 10 to 50 kilobars and a temperature within the range of 1,000.degree. C. to 1,400.degree. C. The advantage of the present invention consists in providing a simple method for the production of the compact which possesses retained strength and cutting properties. The compact of the invention may be most advantageously used for making cutting and grinding tools intended for machining iron-, nickel-, and cobalt-base steels and alloys.
