Grade: YCB012 Workpiece Material: high hardness materials processing categories: CBN content lower finishing, fine grain structure PCBN grade with high hardness (HV3200-3500) good thermal stability and relatively low thermal conductivity , mainly for hardened steel (HRC45-65) of high-speed, high-precision machining continuous or intermittent mild, dry cutting recommended as far as possible. Materials can also be used for finishing of cast iron. Uncoated carbide grade carbide grade class of widely used non-ferrous metals, high temperature alloys and other materials processing in applications reflects the versatility and economy.
