Title
(EN) ROTARY CUTTING HEAD HAVING CUTTING EDGES EXTENDING PAST KEY ACTUATING PORTION
(FR) TÊTE DE COUPE ROTATIVE POURVUE D'ARÊTES DE COUPE S'ÉTENDANT AU-DELÀ D'UNE PARTIE ACTIONNEMENT DE CLÉ
Abstract
(EN) A replaceable milling head (10) rotatable in a cutting direction (RD) about a longitudinal central axis, the central axis (S) defining a forward direction (F) and an opposite rearward direction (R), has a forward cutting portion (20) and a rear threaded coupling portion (40) for coupling to a shank (46). The cutting portion (20) includes two or more key actuating portions (32a, 32c) which assist in mounting the milling head (10) onto the shank (46). The cutting portion (20) includes a plurality of helical chip flutes (26) alternating with cutting edges (28). At least one or more of the cutting edges (28) and flutes (26) extend axially rearward of at least a portion of the key actuating portions (32a, 32c).
(FR) Tête de fraisage remplaçable (10) pouvant tourner dans un sens de coupe (RD) autour d'un axe central longitudinal, l'axe central (S) définissant une direction avant (F) et une direction arrière (R) opposée, a une partie coupe avant (20) et une partie accouplement filetée arrière (40) destinée à être accouplé à une tige (46). La partie coupe (20) comprend au moins deux parties actionnement de clé (32a, 32c) qui facilitent le montage de la tête de fraisage (10) sur la tige (46). La partie coupe (20) comprend une pluralité de cannelures (26) à copeaux hélicoïdales alternant avec des arêtes de coupe (28). Au moins un ou plusieurs des arêtes de coupe (28) et des cannelures (26) s'étendent axialement vers l'arrière d'au moins l'une des parties actionnement de clé (32a, 32c).
