PCBN 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.

The Subaru EJ204 was a 2.0litre horizontallyopposed (or 'boxer') fourcylinder petrol engine with double overhead camshafts. The naturally aspirated E204 engine was initially introduced in the 2005 Subaru GD/GG Impreza and 2006 Subaru BL/BP Liberty as a more powerful alternative to the single overhead cam EJ202 engine, but effectively replaced the EJ202 when the GE/GH Impreza was released in
swift 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 when
The EJ201 and EJ202 engines had an aluminium alloy cylinder head with crossflow cooling. Unlike the EJ20 engine, the intake ports for the EJ201 and EJ202 engines created a tumble swirl motion for air as it entered the cylinder for better mixing of the air and fuel for
