Abstract:
Die Erfindung betrifft ein Fräs- und/oder Drehwerkzeug (1) zum spanabhebenden Bearbeiten von Werkstücken mit wenigstens einer am Werkzeug (1) frei drehbar um eine Achse (Y) gelagerten kreisscheibenförmigen Wendeplatte (2), die eine rotationssymmetrisch zur Achse (Y) ausgebildete Schneide (21) aufweist und die mit ihrer Schneide (21 ) relativ zu einer Oberfläche des zu bearbeitenden Werkstücks bewegt wird, wobei die Wendeplatte (2) ein Trägerelement (3) aufweist, wobei das Trägerelement (3) koaxial zur Achse (Y) einen Wellenstummel (31) hat, der in einer Bohrung (13) im Werkzeug (1) drehbar geführt ist.
Abstract:
L'outil (7B) comporte une arête de coupe (24) située à la jonction entre une face d'attaque et une face de dépouille (23), la face d'attaque présentant une facette avant (26) prévue pour être disposée transversalement à la direction de déplacement (29, 30) relatif entre la pièce (2) et l'outil (7B) lors desdites opérations d'usinage, et une facette inclinée (27) disposée entre la facette avant (26) et la face de dépouille (23), l'arête de coupe (24) étant située à la jonction entre la facette inclinée (27) de la face d'attaque et la face de dépouille (23).
Abstract:
The invention provides a toolholder assembly (10) including a body (12) and a nest (18) that is suitable for holding an insert (14). The nest (18) includes a notch (58) and the body (12) includes a support (20) and protrusion (34) that cooperates with the notch to permit indexing of the nest relative to the support. In one embodiment, the support (20) includes a bias device, such as a spring (430), that at least partially biases the nest (18) toward the support (20) and an adjustment device that can at least partially counter the bias device. The invention is also directed to a toolholder assembly (10) that additionally includes an insert (14) and a clamp (16). The invention further contemplates a method for forming the assembly (10) and a method for adjusting or indexing the orientation of the nest (18).
Abstract:
The invention relates to a cutting insert, intended for chip removing machining, which includes a cutting geometry surface (7), which counted from a cutting edge (11) includes a primary chamfer (24) that transforms into a chip removing surface (25), which is inclined in the direction inwards/downwards in order to permit sinking of a chip being under formation, and which transforms into a deflection surface (26) arranged to be met by the chip and at least initiate deflection or guiding away of the same from the cutting insert. The angle of inclination (δ) of the chip removing surface (25) does not exceed 18°, in addition to which, the level difference N 1 between the primary chamfer and the chip deflection surface (26) amounting to maximally 0,20 mm.
Abstract:
A round cutting insert, normally made of cemented carbide, for turning operations is provided. It comprises a top surface, a round clearance surface (2) and a bottom surface (3). The top surface comprises a number of main, circumferentially spaced chip-breaking grooves (6). Essential for the invention is that each of these main grooves (6) comprises a further chip-breaking groove (16) which is encircled by the main groove. Thanks to these superposed grooves (16), the insert becomes very versatile, with good chip control both at low and high feeds, as well as at small and large cutting depths.
