Abstract

L'invention porte sur un outil (10) qui est destiné à être utilisé pour abraser, rectifier, roder, ou autrement finir ou travailler la surface intérieure d'un alésage, d'une ouverture, d'un cylindre ou d'une pièce à travailler similaire. Ledit outil comprend un élément abrasif (11) qui est porté de façon dépendante autour d'un ensemble mandrin (18). L'élément abrasif (11) présente une fente longitudinale (14), de telle sorte que l'élément abrasif (11) est extensible radialement lors de l'application depuis l'extérieur d'une force provenant de l'intérieur d'un alésage longitudinal (15) formé à travers celui-ci. L'ensemble mandrin (18) comprend une tige filetée (19) sur laquelle est formé un arbre extensible radialement (25), qui est formé par l'application sur et autour de la tige filetée (19) d'une ou de plusieurs douilles à expansion radiale, de préférence cylindriques (26), lesquelles douilles (26) sont séparées et délimitées par une pluralité de douilles fixes radialement, de préférence sphériques (31). L'ensemble mandrin (18) peut également être utilisé comme mandrin de diamètre intérieur pour porter une pièce à travailler subissant un procédé d'usinage.
