Title (EN) INDEXABLE INSERT ROUTER
(FR) DETOUREUSE A PLAQUETTES AMOVIBLES
Abstract:
(EN) A high-speed end-milling router (10) for ramping entry into a workpiece has plate-like hard metal cutting inserts (28) fitted in pockets (30) milled in chip gullet surfaces (24) to present the insert at a desired axial rake angle and with radially inwardly and outwardly facing cutting edges (34, 36, 38, 40). Each insert is secured in its pocket by two countersink headed machine screws (43, 43) whose holding power against centrifugal dislodgement of the insert is reinforced by a projection (46) from the seating surface (48) of the pocket extending into a blind recess (44) molded in the undersurface (41) of the insert.
(FR) L'invention concerne une détoureuse de fraisage combiné (10) à grande vitesse, destinée à entrer selon un angle de rampe dans une pièce à usiner. Ladite détoureuse comporte des plaquettes amovibles en métal dur (28) logées dans des poches fraisées dans des surfaces à gorge cunéenne (24) de sorte que la plaquette soit présentée selon l'angle de pente axiale voulu et que ses bords de coupe (34, 36, 38, 40) soient tournés vers l'intérieur et vers l'extérieur. Chaque plaquette amovible est fixée dans sa poche par deux vis à métal à tête et conique (43, 43) dont la résistance à l'encontre du délogement centrifuge de la plaquette est renforcée par une saillie (46) de la surface d'assise (48) de la poche s'étendant dans un évidement borgne (44) moulé dans la sous-surface (41) de la plaquette.
