A cutting tool having cutting inserts (40) retained in cartridges (18). The location of each cartridge (18) is adjustable by a bidirectional adjustment mechanism having an adjustment screw (54) directed in the direction of adjustment. The adjustment screw(54) has a head(62) and a flexible flange(64) with an annular recess (60) therebetween. A protuberance (72) projecting from the cartridge (18) engages the annular recess (60) with an interference fit thereby coupling the adjustment screw(54) to the cartridge (18). As the adjustment screw (54) is screw rotated about its axis of screw rotation (8) it moves along the axis of screw rotation (8) taking the cartridge (18) with it. Screw rotation of the adjustment screw (54) in opposite senses results in the adjustment of the position of the cartridge (18) in opposite directions. Due to the fact that the protuberance (72) is firmly located in the annular recess (60) of the adjustment screw(54) play or backlash is eliminated.

L'invention porte sur un outil de coupe ayant des inserts de coupe (40) retenus dans des cartouches (18). La position de chaque cartouche (18) est réglable par un mécanisme de réglage bidirectionnel ayant une vis de réglage (54) dirigée dans la direction de réglage. La vis de réglage (54) a une tête (62) et une bride souple (64) avec un creux annulaire (60) entre celles-ci. Une protubérance (72) faisant saillie à partir de la cartouche (18) vient en prise avec le creux annulaire (60) avec une adaptation par interférence, ce qui permet d'accoupler la vis de réglage (54) à la cartouche (18). A mesure que la vis de réglage (54) est vissée autour de son axe de rotation (8), elle se déplace le long de l'axe de rotation de vis (8) en entraînant la cartouche (18) avec elle. La rotation de vis de la vis de réglage (54) dans les sens opposés conduit au réglage de la position de la cartouche (18) dans des directions opposées. En raison du fait que la protubérance (72) est fermement positionnée dans le creux annulaire (60) de la vis de réglage (54), le jeu est éliminé.
