Title (EN) IMPROVEMENTS IN OR RELATING TO SLOTTING MACHINES
(FR) AMELIORATIONS APPORTEES A DES MORTAISEUSES OU CONCERNANT DES MORTAISEUSES
Abstract:
(EN) A machine for machining blind-ended slots longitudinally disposed within the bore of a sleeve (1) held in a chuck (4) in a work holding spindle (5) indexable about a rotational axis, a reciprocable cutting tool (2) mounted on a cutting spindle (12) the axis of which is offset from and at right angles to the rotational axis of the work holding spindle (5) in which the cutting tool (2) executes a succession of progessively deeper cutting and subsequent return strokes so that a number of blind-ended slots are machined in the sleeve (1) characterised in the provision of a slidable support (6) for the work holding spindle (5) to slide the work holding spindle (5) axially relative to the cutting spindle (12) a distance such that the cutting tool is radially and axially clear of the bore when all slots are machined, cutting strokes of the cutter being discontinued.
(FR) L'invention concerne une machine servant à usiner des mortaises borgnes disposées dans le sens longitudinal à l'intérieur de l'alésage d'une douille (1) maintenue dans un mandrin (4) dans une broche (5) retenant la pièce à usiner, et pouvant tourner de façon précise autour d'un axe de rotation, et un outil de coupe (2) à mouvement de va-et-vient monté sur une broche de coupe (12) dont l'axe est déporté de 90° par rapport à l'axe de rotation de la broche retenant la pièce à usiner (5). L'outil de coupe (2) exécute une série de coupes de plus en plus profondes et des courses subséquentes de retour de façon qu'un nombre de mortaises borgnes soient usinées dans la douille (1). Un support coulissant (6) de la broche (5) retenant la pièce à usiner sert à faire coulisser la broche retenant la pièce à usiner dans le sens axial, par rapport à la broche de coupe (12), sur une distance telle que l'outil de coupe soit radialement et axialement dégagé de l'alésage lorsque toutes les mortaises ont été usinées, les courses de coupe de l'outil de coupe étant alors interrompues.
