Abstract

Ce dispositif est du type de ceux munis d'outils rotatifs et dans lesquels deux poussoirs radiaux portant chacun un outil et déplaçables en sens contraire l'un de l'autre sont montés dans une tête porte-outils fixée sur une broche apte à être entraînée en rotation et à coulisser longitudinalement, lesdits poussoirs etant actionnables au moyen d'une tige de manoeuvre disposée à l'intérieur de la broche et commandée par un piston de copiage placé à l'extrémité arrière de la broche. Dans le dispositif selon l'invention, il est prévu un premier système compensateur des forces centrifuges sous la force de ressorts 22, 23 sollicités par les mouvements des poussoirs radiaux et, comme second système compensateur, un autre piston soumis à l'action des forces hydrauliques, ou piston 30 est relié à la tige de manoeuvre 26. On obtient ainsi une élimination parfaite de l'effet gênant des forces centrifuges.
