Abstract: 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 with a metallic binder system and is sintered under HPHT conditions. The improvement incorporates alloys of aluminum in the metallic binder system.

Abstract: Multi-step milling processes to prepare cBN composite powder forms a first powder mixture by adding a binder and a first cBN component, mills the first powder mixture for a first time period, combines a second cBN component with the milled first powder mixture to form a second powder mixture, and mills the second powder mixture for a second time period (less than the first time period) to form the cBN composite powder. A ratio of the D50 value of the second cBN component to the D50 value of the first cBN component is at least 3.0. Two-step milling with different milling times for the two cBN component fractions controls the amount of mill debris in the cBN composite powder mixture. Further processing of the cBN composite powder under HPHT conditions forms a cBN-based ceramic with an average value of a cBN particle free diameter of less than 2.0 microns.
