Title
(EN) DEVICE FOR THERMALLY INSULATING A MACHINING ATTACHMENT AND MACHINING ATTACHMENT PROVIDED WITH SUCH A DEVICE
(FR) DISPOSITIF D'ISOLATION THERMIQUE D'UN ATTACHEMENT D'USINAGE ET ATTACHEMENT D'USINAGE POURVU D'UN TEL DISPOSITIF
Abstract
(EN)
Device for thermally insulating a machining attachment (1) intended to secure a machining tool (3) to a machine-tool spindle, of the type having a body (2) of axis of revolution Z, a first end (20) of which comprises means for mounting the said machining tool (3) and a second end (21) of which comprises means of assembly with said spindle, said body (2) having passing through it a passage of axis Z, opening at each of the first and second ends (20, 21), said passage being intended for the circulation of a lubricating fluid between the machine-tool and said machining tool (3) and being equipped, at said first and second ends (20, 21) with a first end-piece (7) for fluidic connection to said tool (3) and with a second end-piece (4) for fluidic connection to said spindle. The device comprises a thermally insulated pipe (5) configured to be inserted inside said passage and to collect said lubricating fluid.
(FR)
Dispositif d'isolation thermique d'un attachement d'usinage (1) destiné à la solidarisation d'un outil d'usinage (3) avec une broche d'une machine-outil, du type présentant un corps (2) d'axe de révolution Z dont une première extrémité (20) comporte des moyens de montage dudit outil d'usinage (3) et une seconde extrémité (21) comporte des moyens d'assemblage avec ladite broche, ledit corps (2) étant traversé par un passage d'axe Z, débouchant au niveau de chacune des première et deuxième extrémités (20, 21), ledit passage étant destiné à la circulation d'un fluide de lubrification entre la machine-outil et ledit outil d'usinage (3) et étant muni, au niveau de ladite première et seconde extrémités (20, 21), d'un premier embout de raccordement fluidique (7) avec ledit outil (3) et d'un second embout de raccordement fluidique (4) avec ladite broche. Le dispositif comporte un conduit (5) thermiquement isolé configuré pour être inséré dans ledit passage, et pour accueillir ledit fluide de lubrification.
