Title
(EN) INDEXABLE PARTING BLADE WITH CIRCUITOUS COOLANT CHANNELS
(FR) LAME DE SÉPARATION INDEXABLE À CANAUX DE FLUIDE DE REFROIDISSEMENT INDIRECTS
Abstract
(EN) An indexable parting blade has opposite blade first and second sides, a blade peripheral edge, a central index axis, and at least first, second and third insert pockets located along the blade peripheral edge. The parting blade also has first, second and third coolant channels, each forming a coolant path from a corresponding inlet to a corresponding one of the insert pockets. Each coolant channel includes a rake outlet opening out to a rake side of its corresponding insert pocket and a relief outlet opening out to a relief side of that same insert pocket. The inlet corresponding to a given coolant channel is located further from that coolant channel’s insert pocket than at least one of (a) the inlet corresponding to a different coolant channel, and (b) the central index axis.
(FR) Une lame de séparation indexable a des premier et second côtés de lame opposés, un bord périphérique de lame, un axe d'indexation central et au moins des première, deuxième et troisième poches d'insert situées le long du bord périphérique de lame. La lame de séparation comporte également des premier, deuxième et troisième canaux de fluide de refroidissement, chacun formant un trajet de fluide de refroidissement d'une entrée correspondante à une poche correspondante parmi les poches d'insert. Chaque canal de fluide de refroidissement comprend une sortie de coupe débouchant sur un côté de coupe de sa poche d'insert correspondante et une sortie d’évacuation débouchant sur un côté évacuation de cette même poche d'insert. L'entrée correspondant à un canal de fluide de refroidissement donné est située plus loin de la poche d'insert du canal de fluide de refroidissement (a) que l'entrée correspondant à un canal de fluide de refroidissement différent et/ou (b) que l'axe d'indexation central.
