Abstract
PCBN material consisting of cBN grains dispersed in a matrix, the content of the cBN grains being in the range of about 35 to about 70 volume % of the PCBN material. The matrix comprises at least one kind of chemical compound that includes aluminum (Al) and at least one kind of chemical compound that includes titanium (Ti). The size distribution of the cBN grains exposed at a surface of the PCBN material is such that at least about 50% percent of the total equivalent circle area (ECA) arises from cBN intercept lengths up to 5 microns. At least about 20 percent of the total ECA arises from cBN intercept lengths greater than about 5 microns.
