Title (EN) BORING DEVICE PROVIDED WITH A RADIALLY ADJUSTABLE TOOL
(FR) DISPOSITIF D"ALESAGE MUNI D"UN OUTIL A REGLAGE RAIDAL
Abstract: front page image
(EN)The spindle (9) of a machine tool carries a boring device provided with a boring bar (1) and with a tool (2). The boring bar (1) is connected to a back plate (8) of the spindle (9) by means of torsion bars (3). A support arm (11) fixed to the boring bar (1) bears on a low gradient surface (14) of an adjusting body (16) which may be moved axially in a guide (17) by a thrust bar (23) to impact a radial motion to the tool (2). Facing the inclined surface (14) there is provided a second inclined surface (15) between which the support arm (11) is positively guided. The radial adjustment of the tool (2) allows the clearing of the tool (2) from a machined surface during the backward motion of the tool and the compensation of the wear of the tool during a following machining operation.
(FR)La broche (9) d"une machine-outil porte un dispositif d"alesage muni d"une barre d"alesage (1) et d"un outil (2). La barre d"alesage (1) est reliee a un faux-plateau (8) de la broche (9) au moyen de barres de torsion (3). Un bras de support (11) fixe a la barre d"alesage (1) s"appuie sur une surface (14) a faible pente d"un corps de reglage (16) qui peut etre deplace axialement dans un guide (17) par une barre de poussee (23) pour impartir a l"outil (2) un mouvement radial. En face de la surface inclinee (14) se trouve une seconde surface inclinee (15) entre lesquelles le bras de support (11) est guide positivement. Le reglage radial de l"outil (2) permet de degager l"outil (2) d"une surface usinee lors du recul de l"outil et de compenser l"usure de l"outil lors d"une operation d"usinage suivante.
