摘要

A method of abrasion abrading a surface of a work piece, comprising the operations of forming an enclosure with said surface as a wall thereof, applying suction to said enclosure, inducing the passage of primary air to the enclosure by extracting the contained air in the enclosure by aspiration, while limiting the entry of secondary air from the surrounding atmosphere into the enclosure around the periphery of said surface, entraining abrasive in said primary air before the entry of the latter into the enclosure, directing the abrasive that enters the enclosure against said surface and drag the spent abrasive in the air that is being removed from the enclosure by aspiration.
