Title
(EN) MACHINE TOOL EXTENSION AND METHOD OF FORMING THE SAME
(FR) RALLONGE DE MACHINE-OUTIL ET SON PROCEDE DE FORMATION
Abstract
(EN) A machine tool extension (10) for interfacing a cutting tool (12) having a generally cylindrical shank portion (30) to a tool holder (14) having a central opening (22). The extension (10) comprises an elongate, generally cylindrical shank member (34) having first end (36) and a reduced diameter second end (39). The first end (36) of the shank member (34) is insertable into and securable within the central opening (22) of the tool holder (14). The extension (10) further comprises a bushing member (44) having an aperture (46) extending longitudinally therethrough. The second end (39) of the shank member (34) is insertable and securable within one end of the aperture (46), with the shank portion (30) of the cutting tool (12) being at least partially insertable into and securable within the other end of the aperture (46). The shank member (34) is formed to have an outer diameter which slightly exceeds the diameter of the central opening (22) of the tool holder (14).
(FR) La présente invention concerne une rallonge (10) de machine-outil permettant de connecter un outil de coupe (12) muni d'une partie queue (30) généralement cylindrique à un porte-outils (14) comportant une ouverture centrale (22). Ladite rallonge (10) comprend un élément de tige (34) généralement cylindrique muni d'une première extrémité (36) et d'une deuxième extrémité (39) de diamètre inférieur. La première extrémité (36) de l'élément de tige (34) peut être insérée et fixée dans l'ouverture centrale (22) du porte-outils (14). La rallonge (10) comprend également une douille (44) percée d'une ouverture (46) s'étendant dans le sens longitudinal. La deuxième extrémité (39) de l'élément de tige (34) peut être insérée et fixée dans une extrémité de l'ouverture (46), la partie queue (30) de l'outil de coupe (12) pouvant au moins être partiellement insérée et fixée dans l'autre extrémité de l'ouverture (46). L'élément de tige (34) est formé de manière qu'il présente un diamètre extérieur légèrement supérieur au diamètre de l'ouverture centrale (22) du porte-outils (14).
