Abstract:
Die vorliegende Erfindung betrifft einen Kurbelwellenfräser (1), mit einem scheibenförmigen, um eine zur Scheibenebene senkrechte Achse drehbaren Grundkörper (2), an dessen Peripherie Aussparungen (3, 4, 5) zur Aufnahme von Wendeschneidplatten (6, 7, 8) zur Abtragung eines Aufmaßes an einem Kurbelwellenrohling vorgesehen sind, wobei mindestens ein Teil der Aussparungen (3, 4, 5) sowohl in radialer Richtung als auch in mindestens einer axialen Richtung des Grundkörpers (2) offen ist und wobei eine erste Gruppe dieser Aussparungen (3, 4) für die Aufnahme von Schneideinsätzen (6, 7) vorgesehen ist, welche für das Abtragen des Aufmaßes an einem einen Wellenzapfen begrenzenden Ölbund ausgelegt sind. Um einen Kurbelwellenfräser zur Verfügung zu stellen, der den zunehmenden Anforderungen bezüglich Form- und Lagetoleranz an einen Kurbelwellenfräser gewachsen ist und zugleich die notwendige Zeit für die Feinjustierung des Kurbelwellenfräsers verringert, wird erfindungsgemäß vorgeschlagen, dass nur ein Teil der ersten Gruppe von Aussparungen (3) Einrichtungen (9) zum Einstellen der axialen Position der jeweils darin aufgenommenen Wendeschneidplatte (6) aufweist.
Abstract:
Die Erfindung betrifft ein Werkzeug zum Dreh-Dreh- Räumen oder Außenfräsen von Werkstücken, die bei der Zerspanung um ihre Längsachse rotieren, mit einem scheibenförmigen Werkzeugträger, der peripher angeordnete, jeweils mit einem Schneideinsatz (12, 13, 14) bestückte Kassetten (20) aufweist, die auf einem ring- oder teilringförmigen oder segmentförmigen, lösbar entweder unmittelbar an einer Maschinenspindel oder mittelbar über einen Adapter an einer Maschinenspindel befestigten Träger (11) befestigt sind. Erfindungsgemäß weist die Kassette (20) einen Plattensitz mit einer Auflagefläche (21) und zwei Seitenflächen (22, 23) als Anlageflächen für den Schneideinsatz (12, 13, 14) auf und ist über einen Verstellkörper (27) radial einstellbar sowie über einen Klemmkörper (18) fixierbar, ferner weist die Kassette (20) parallel zur Auflagefläche (21) für den Schneideinsatz (12, 13, 14) eine schlitzförmige Nut (30) mit gegenüberliegenden Nutwänden auf, deren Abstand und Neigung zueinander mittels einer Verstellschraube (33) einstellbar ist, so dass die Winkellage der (21) Auflagefläche veränderbar ist.
Abstract:
A rotary cutting tool includes a tool holder and a tool body releasably attached thereto. The tool body has a cutting portion that includes a peripheral insert pocket, for retaining a cutting insert. The tool holder includes an adjustment arrangement that includes a biasing member, movably attached to the tool holder, having a biasing portion. The cutting portion is adjustable between a non-flexed position and a flexed position. In the flexed position, the cutting portion is elastically deformed in a forward direction due to biasing engagement with the biasing portion, thereby adjusting the axial position of the insert pocket and thus the cutting insert.
Abstract:
An adjustable insert cutting angle cutting tool (20) comprising a tool holder (24) having a cartridge receiving pocket (32), an insert cartridge (22) clamped in the cartridge receiving pocket (32) by a clamping member (26), and a cutting insert (28) removably retained in the insert cartridge (22). The clamping member (26) is operated by a separate fastening member (36). The cutting insert (28) has at least one operative cutting portion (30), and the insert cartridge (22) is oriented in a cartridge receiving pocket (32) of the tool holder (24) so that the operative cutting portion (30) encounters a workpiece (34) at an insert cutting angle (al). The clamping member (26) has a clamping surface (52) with at least one clamping zone (Czl), and the same at least one clamping zone (Czl) makes contact with a nonplanar clamped surface (54) of the insert cartridge (22) for different values of insert cutting angle(al). The insert cutting angle (al) is increased or decreased by reorienting the insert cartridge (22) in the tool holder (24), following release of the fastening member (36).
Abstract:
A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the cutter head comprises positive blade seating surfaces (16, 18) and the capability to clamp the blades (8) tight to the positive seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.
Abstract:
A bevel gear manufacturing face cutter head (20) for face hobbing and face milling wherein the cutter head comprises blade positioning slots (20) having a four-sided shaped cross-section and positive blade seating surfaces (22, 24) and having the capability to clamp cutting blades (8) tight to the positive blade seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.
Abstract:
The present invention is related to a cutting insert (1) comprising a cuboid body having a substantially square top face (2) and a bottom face (3), said top face (2) and bottom face (3) being connected by means of four peripheral adjoining side surfaces, wherein at least two cutting edges (5) are formed at the transition of the top face (2) to at least two side surfaces (4), those cutting edges (5) defining a plane of the top face (2). In order to provide a cutting insert (1) and a corresponding tool (20, fig.5) which are suited to produce valve seat surfaces with high precision the plane defined by the top face cutting edges (5) of a cutting insert (1) according to the invention has maximum dimensions of 7 mm x 7 mm, the bottom face (3) having a supporting surface which is formed exactly parallel to the plane defined by the top face cutting edges (5) by means of grinding within a tolerance of less than 5 angular minutes. The corresponding cutting tool (20, fig.5) has ground locating surfaces with the same tolerance.
Abstract:
The milling-cutter comprises a disc-shaped base body (1) presenting a central fixing drilling (2) and fixing housings evenly distributed at the periphery of the base body, opened at the front part of the latter and intended to receive and hold a cutting plate support (4) which may be adjusted and secured into its housing (3) independently either in the axial direction or in the radial direction and which carries a cutting plate (6 resp. 62) arranged so that its main plane extends substantially radially. In order to adjust each cutting plate by rotation about an imaginary axis extended transversally to the central axis of the base body, independently of the axial and radial adjusting, the cutting plate (6) is arranged into a recess (10) adapted to the shape of the cutting plate in a cutting plate cage (11) pivotingly mounted on the cutting plate support (4) about an imaginary axis substantially perpendicular to a radial plane containing the central axis (5) of the base body (1) and which may be locked in relation to the cutting plate support (4). Preferably, the milling-cutter is designed so that each cutting plate support (4) is guided and mounted on a support (36) so as to be displaced in a radial direction and locked, and so that each support (36) is guided and held so as to be displaceable and lockable in parallel to the central axis of the base body (1) with respect to the latter.
Abstract:
A cutter head (4, 6) having a lock spring (30) utilized with an adjustment screw (16) for preventing the adjustment screw from loosening during machining. Once positioned by turning the adjustment screw, a cutting blade (8) will not change position in a mounting slot (10) due to a loosening adjustment screw.
Abstract:
A rigid cartridge (200) for universal holding system comprises a cylindrical body (201), a guiding and locating body (204) connected to bottom side of cylindrical body (201), and a combination screw (205) having a left hand thread (207) and a right hand thread (208). Wherein the cylindrical body (201) includes a flat (203) for locking the cartridge (200) with a cutter body (209) by using a locking screw. This cartridge is simple in design, and is possible to adjust in micron level, and can be used universally in multiple applications.
