FA20E and FA20F Subaru Engines
The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chaindriven double overhead camshafts per cylinder bank. The four valves per cylinder two intake and two exhaust were actuated by roller rocker arms which had builtin needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.
pcbn inserts in solid cbn and tipped cbn for hard turning
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
