CA 2744262

A monolithic cutting insert (40), which receives coolant via a coolant port (32), is formed by the consolidation of a cavity member (42), a first core member (44) adjacent the first rake surface (52) of the cavity member (42), and a second core member (46) adjacent the second rake surface (54) of the cavity member (42). Cutting insert (40) contains a fifth internal fluid passage-way (300), which provides fluid communication between a fifth notch (256), which is adjacent second rake surface (54) and in communication with the coolant port (32), and a first fluid spray chamber adjacent the first rake surface (52). Coolant sprays from the first fluid spray chamber toward an adjacent first cutting edge (160) adjacent the first rake surface (52).

La présente invention porte sur un insert de coupe monolithique (40) qui reçoit un liquide de refroidissement par l'intermédiaire d'un orifice de liquide de refroidissement (32). Ledit insert de coupe est formé par la consolidation d'un élément de cavité (42), d'un premier élément central (44) adjacent à la première surface de dégagement (52) de l'élément de cavité (42), et d'un second élément central (46) adjacent à la seconde surface de dégagement (54) de l'élément de cavité (42). L'insert de coupe (40) contient un cinquième conduit de fluide interne (300) qui assure une communication fluidique entre une cinquième encoche (256) qui est adjacente à la seconde surface de dégagement (54) et en communication avec l'orifice de liquide de refroidissement (32), et une première chambre de pulvérisation de fluide adjacente à la première surface de dégagement (52). Le liquide de refroidissement est pulvérisé depuis la première chambre de pulvérisation de fluide vers un premier bord de coupe adjacent (160) qui est adjacent à la première surface de dégagement (52).
