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.
Subaru's EJ255 engine was a turbocharged 2.5litre horizontallyopposed (or 'boxer') fourcylinder engine. For Australia, the EJ255 engine was introduced in the Subaru SG Forester XT in 2003, but subsequently offered in the GD/GG Impreza WRX and BL Liberty GT (see table below). Developed in conjunction with the more powerful EJ257 engine, key features for the EJ255 engine included its
tipped pcd inserts in 80 degree diamond shape C for hard turning nonferrous metals of aluminum, the pcd insert cutting edges are made with polycrystalline diamond, indexable inserts with pcd working tips are precision cutting tools, which are used in cnc super fine finish machining, turning and milling automobile engine block, cylinder head, gearbox, cast aluminum alloy with silicon content

Subaru's EJ257 was a turbocharged, 2.5litre horizontallyopposed (or 'boxer') fourcylinder engine. For Australia, the EJ257 engine was introduced in the Subaru GD Impreza WRX STi in 2005 and subsequently powered the GE/GH Impreza WRX STi and V1 WRX.Effectively replacing the 2.0litre EJ207 engine, the EJ257 engine was a member of Subarus Phase II EJ engine family; key features
tipped 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 for
