摘要： The present invention provides a cubic boron nitride-based sintered material excellent in durability and usable for a cutting tool material capable of carrying out high speed cutting of at least a high grade cast iron represented with a Ni-Resist cast iron and an austempered cast iron and having a long life. The present invention further provides a method for manufacturing the cubic boron nitride-based sintered material. The method for the production of a cubic boron nitride-based sintered material includes preparing a starting mixture by mixing particles of cubic boron nitride with a binding powders based on the system of TiCN, Si3N4, Al2O3, and CrxN, wherein x varyies from 1 to 2.7; and subjecting the starting mixture to a sintering process under pressure and at the same time at a high temperature; and recovering a sintered product.
