Abstract

Artículo abrasivo que presenta determinados niveles mínimos de permeabilidad a los fluidos, que comprende entre aproximadamente 40 y 80% envolumen de porosidad interconectada, y cantidades eficaces de grano abrasivo yaglutin ante para llevar a cabo operaciones de amolado de bajadureza y de amolado de corte profundo. La alta permeabilidad al pasaje de los fluidos y la porosidad interconectada provee una estructura abierta decanales que permiten el pasaje defluido a tra vés del artículo abrasivo, así como la remoción del barro de amolado de la pieza trabajada durante lasoperaciones de amolado.
