tipped pcbn inserts with brazed cbn cutting edges for hardtipped pcbn inserts with brazed cbn cutting edges are used for machining ferrous hard metals such as nodular cast iron, hardened steel, high speed steel, die steel, bearing steel, cemented steel, heat resisting steel, carbon tool steel, chromium and nickel molybdenum alloy. the working tips of cbn inserts are made by pure polycrystalline cubic boron nitride, cbn tipped inserts are mainly forpcd inserts for turning and milling aluminum alloyswift manufacturing ltd supply with polycrystalline diamond pcd inserts for turning and face milling, pcd cutting tool inserts which is an indexable inserts widely used in cnc machining for fine finishing aluminum alloy and tungsten carbide, such as work part of aumotive cylinder head,wheel hub,pressure tanks,gearbox shaft,valves and composite bearing materials, different pcd grain sizes whenpcbn inserts in solid cbn and tipped cbn for hard turningpcbn inserts for turning cast iron and hardened steel pcbn is the second hardest material in the world, and cbn related high precision cutting tools are introduced to industry, achieved high productivity and cost reductions. pcbn is the short name of polycrystalline cubic boron nitride, and pcbn inserts are mainly for the hard metal turning to replace the conventional machining way of grinding.
