Tool Wear of Polycrystalline Cubic Boron Nitride Compact in Cutting Hardened Steel
Journal of the Japan Society of Powder and Powder Metallurgy, 2008 Using polycrystalline cubic boron nitride compact (cBN) tools, which had the different cBN contents, the influences of both cBN contents and cutting speed on tool life in turning of hardened steel (SKD11, 60HRC) were investigated. Four types of cBN tools (cBN contents of 45 %, 55 %, 65 % and 75 % respectively) and a coated cBN tool (cBN contents of 55 %
