Title (EN) AXIAL MACHINING DEVICE
(FR) DISPOSITIF D'USINAGE AXIAL
Abstract:
(EN) The present invention relates to an axial machining device (1), which comprises a tool-holder spindle (3) rotating inside a frame (2), the latter housing a transmission system (5) causing the automatic advance of the spindle relative to the frame (2) during the rotation of the tool-holder spindle, said transmission system (5) comprising an advance pinion (15) screwed onto the spindle (3), said device being characterised in that it includes an elastic return member (40) biasing the advance pinion (15) in a first axial direction, preferably opposite the advance direction (A) of the spindle (3), and in that said device comprises a first bearing (50) comprising bearing members (51) rolling on a corrugated bearing surface having an axial component, such as to periodically bias the advance pinion (15) to move in a second direction opposite the first direction, such that the rotation of the spindle (3) is accompanied by an axial vibration movement.
(FR) La présente invention concerne un dispositif d'usinage axial (1), comportant une broche porte outil (3) tournant à l'intérieur d'un bâti (2), ce dernier logeant un système de transmission (5) provoquant l'avance automatique de la broche relativement au bâti (2) sous l'effet de l'entraînement en rotation de la broche porte outil, ce système de transmission (5) comportant un pignon d'avance (15) vissé sur la broche (3), dispositif caractérisé par le fait qu'il comporte un organe de rappel élastique (40) sollicitant le pignon d'avance (15) dans une première direction axiale, de préférence contraire à la direction d'avance (A) de la broche (3), et par le fait qu'il comporte un premier roulement (50) comportant des organes de roulement (51) roulant sur une surface de roulement ondulée avec une composante axiale, de façon à solliciter périodiquement en déplacement le pignon d'avance (15) dans une deuxième direction opposée à la première, de telle sorte que la rotation de la broche (3) s'accompagne d'un mouvement vibratoire axial.
