ABSTRACT:
The purpose of the present invention is to provide a cubic boron nitride based sintered material having excellent durability and capable of cutting at least spheroidal graphite cast iron at high speed and usable in a cutting tool having a long life, and a production method of this cubic boron nitride based sintered material. The present invention resides in a production method of a cubic boron nitride based sintered material characterized in that a mixing raw material is produced by mixing powder of Ti.sub.(1-x) Al.sub.x N(x=0.05.about.0.70) and the powder of a cubic boron nitride, and is next sintered. A compounding ratio of the above mixing raw material is preferably set such that this mixing raw material includes 10 to 90% of the above Ti.sub.(1-x) Al.sub.x N(x=0.05.about.0.70) by volume and 10 to 90% of the above cubic boron nitride by volume.
