More Information
Summary:A composite body is provided that can include abrasive grains and at least one pore within a bond matrix, the abrasive grains including cubic boron nitride (cBN) and the bond matrix including a polycrystalline ceramic phase. The bonded abrasive may have a Modulus of Rupture (MOR) of not less than about 40 MPa. Certain embodiments may have porosity, such as, greater than about 5.0 vol %.
