Abstract

Porte-outil d'alésage à opérations multiples, composé d'un corps formant guide central d'alésage, fixé en extrémité d'une broche rotative, et comportant un coulisseau porte-grains d'usinage à course oblique, commandé par une barre coulissante coaxiale avec ce corps et la broche. Le coulisseau comporte sur sa face frontale deux grains de chanfreinage par lamage, à angle et rayon d'attaque frontal différents, et un grain de dressage par chariotage oblique, le recul du coulisseau assurant conjointement le retrait des grains de chanfreinage et le mouvement de chariotage du grain de dressage. Application à la réalisation d'alésages cylindriques et d'usinages coniques rigoureusement concentriques, et en particulier, aux opérations sequentielles de finition, en grande série, des sièges et guide de soupapes de culasses de moteurs à combustion interne.Multi-operation reaming tool holder, composed of a body forming a central boring guide, fixed at the end of a rotating spindle, and comprising an oblique stroke machining grain holder, controlled by a sliding bar coaxial with this body and the spindle. The slide comprises on its front face two chamfering grains by countersinking, with different front angle and leading radius, and a dressing grain by oblique turning, the slide backwards jointly ensuring the withdrawal of the chamfering grains and the turning movement. dressage grain. Application to the production of cylindrical bores and strictly concentric conical machining, and in particular to the sequential finishing operations, in large series, of the seats and valve guides of the cylinder heads of internal combustion engines.
