Abstract:
La présente invention concerne un outil (1) de coupe rotatif multi-matériaux et un procédé de fabrication d'un tel outil qui comporte au moins une arête (8, 9) de coupe continue ou sensiblement continue composée d'au moins deux matériaux différents successifs. L'extrémité ou sommet (10) de l'outil est un point excentré par rapport à l'axe de rotation (5) de l'outil.
Abstract:
A drill bit setting device (40) includes a holder (42) for holding in use a drill bit (10) substantially in alignment along a longitudinal axis (76) of the bit (10). The drill bit setting device (40) includes first limit means (70) for limiting movement of the bit (10) along the axis (76) and second limit means (72) for limiting rotational movement of the bit (10) around the axis (76). The first and second limit means (70), (72) define a pre determined set position relative to the holder (42).

Abstract:
La broche (4) à corps cylindrique présentant les deux zones coaxiales (26), munie d'une portée (28) de fixation de meule et des moyens de raccordement (29 et 30), est placée sur la paroi (3) du socle (1) de manière que les zones (26) reposent chacune selon deux lignes parallèles sur les surfaces 8 des appuis en Vé (7). Le couvercle (15) est alors rabattu autour de l'articulation (23) de manière que la vis (25) s'engage dans le taraudage (14) de la colonnette (11) et que le serrage de la vis de fixation (25) assure une flexion élastique contrôlée des lamelles (20). Le socle (1) est fixé à l'endroit voulu de la machine de meulage par des vis engagées dans les forures (5).
Abstract:
An apparatus (10) for verifying the identity and geometry of drill bits, re-sharpening the cutting tip of a drill bit and re-positioning a locating ring upon the shank portion of the drill bit. The apparatus comprises a housing having a pair of cassette trays (54), a pair of primary cleaning assemblies (80), a pair of secondary cleaning assemblies (180), a pair of inversion assemblies (85), a pair of workhead assemblies (96), a bumping assembly (146), and a loader assembly (62). The workhead and loader assemblies are used to transport drill bits between the cassette trays and other assemblies in a sequence controlled by a programmable control device. The control device is electrically interfaced to each of the assemblies and allows at least two drill bits to be processed simultaneously.
Abstract:
The part to be machined (2) is attached so that its axis lies in a position exactly determined relative to the base of the machine (1) and to the pedestal (3) due to the flanges (8) and the rear face (9) of the V formed on the pedestal, and due to an intermediate member (11) having the shape of a crown sector in which the concave cylindrical faces (23) are adapted to the part (2). The part is pressed against the faces (23) by a lug (14) actuated by the calliper (15). The part (2) can be rotated by a floating pin actuated by a servomotor in a determined position relative to the base of the machine (1).
