La minería es una actividad económica del sector secundario cuando nos referimos a la extracción de minerales, y del sector energético si hacemos referencia a la extracción de combustibles fósiles.Es representada por la explotación o extracción de los minerales que se han acumulado en el suelo y subsuelo en forma de yacimientos. Dependiendo del tipo de mineral a extraer la actividad se

Subaru''s EJ251 and EJ252 were 2.5-litre horizontally-opposed (or ''boxer'') four-cylinder petrol engines. For Australia, the EJ251 engine was first introduced in the Subaru BE/BH Liberty in 1998 and subsequently offered in the BH Outback, GD/GG Impreza RS and Subaru SG Forester. For the Subaru BL/BP Liberty and BP Outback, the EJ251 was replaced by the EJ252 engine.

The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chain-driven double overhead camshafts per cylinder bank. The four valves per cylinder – two intake and two exhaust – were actuated by roller rocker arms which had built-in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.

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.
