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:

Abstract:
The present invention provides a cartridge adjustment tool for adjusting the axial position of cartridges of a slotting cutter. The adjustment mechanism has a body axis of rotation and comprises a body peripheral surface that extends between a body front surface and a body rear surface. The body is provided with threaded through bores, each of which receives therein a threaded portion of a threaded bolt. When the adjustment mechanism is mounted on a mutual arbor with a slotting cutter having cartridges, each of the threaded bolts is opposite a force engagement area of the associated cartridge. By turning the head portion of the threaded bolts, each of the cartridges is axially displaced and the axial position of each of the cartridges may be individually set.

Abstract:
A micro-adjustable differential screw assembly (22, 24, 24'). The micro-adjustable differential screw assembly (22, 24, 24') can be mounted directly to a boring bar (10) or to a mounting cartridge (20), which in turn, can be mounted to the boring bar (10). An axial micro-adjustable differential screw assembly (22) provides fine adjustment of an axial position of the cutting insert (26), while a radial micro-adjustable differential screw assembly (24, 24') provides fine adjustment of a radial position of the cutting insert (26). The differential screw assembly (22, 24, 24') includes a rotatable drive screw (28, 58, 58') with threads (35, 65, 92, 94) of different thread pitches, and a non-rotatable adjusting screw (30, 60, 60') with threads (35, 65, 102) for mating with the drive screw (28, 58, 58'). The difference in the thread pitches of the drive screw (28, 58, 58') causes a greatly reduced axial and radial movement of the boring cartridge (20) in relation to the relative movement of the drive screw (28, 58, 58'), thereby providing fine adjustment in the axial and radial position of the cutting insert (26).
Abstract:
An adjustable lead angle toolholder is disclosed for selectively cutting a workpiece at 30 DEG , 45 DEG , or 60 DEG angles. The toolholder may have a rotatable, cylindrical endmill body (5) that includes a radially-oriented wall (9) or a stationary, square shank having a planar wall on its distal end. The toolholder further includes a cutting insert (18) having at least one linear cutting edge (18), and a mounting assembly (11) for pivotally mounting the insert (18) onto the wall (9) of the endmill body (5) such that a lead angle of the linear cutting edge (19) is adjustable with respect to the outer periphery of the toolholder body.
Abstract:
A cutting tool having cutting inserts (40) retained in cartridges (18). The location of each cartridge (18) is adjustable by a bidirectional adjustment mechanism having an adjustment screw (54) directed in the direction of adjustment. The adjustment screw(54) has a head(62) and a flexible flange(64) with an annular recess (60) therebetween. A protuberance (72) projecting from the cartridge (18) engages the annular recess (60) with an interference fit thereby coupling the adjustment screw(54) to the cartridge (18). As the adjustment screw (54) is screw rotated about its axis of screw rotation (8) it moves along the axis of screw rotation (8) taking the cartridge (18) with it. Screw rotation of the adjustment screw (54) in opposite senses results in the adjustment of the position of the cartridge (18) in opposite directions. Due to the fact that the protuberance (72) is firmly located in the annular recess (60) of the adjustment screw(54) play or backlash is eliminated.
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 milling tool comprises a rotatable supporting body (1) having detachable cassettes (5) upon which cutting inserts (6) are mounted, said cutting inserts (6) being provided with cutting edges. Two serrated surfaces (9, 10) are provided in order to connect the individual cassette (5) with the supporting body (1), a first one (9) of said serrated surfaces being located upon the periphery of the supporting body and facing outwards from the supporting body while the other serrated surface (10) is formed at an inner side of the cassette. By this location of the cassettes the supporting body may be equipped with an increased number of cassettes compared to what has been possible in connection with prior art.
