摘要:
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.

A system for attaching a cutting member (30, 230, 430, 530) to a cutter body (13, 513) includes a pin (50, 150, 250, 4-50, 550), a clamping bolt (60, 260, 460, 560) and an adjustment bolt (70, 270, 470, 570). The pin has a longitudinal axis and at least a first attachment bore (52, 152, 452) and a second attachment bore (53, 153, 453). The clamping bolt has a clamping section which is formed to releasably secure the cutting member to the cutter, body and has a first attachment section (61) which is formed to be releasably secured in the first attachment bore of the pin. The system may have an adjustment bolt that has an adjustment section which is formed to adjust the position of the cutting member relative to the cutter body and has a second attachment section (71) which is formed to be releasably secured in the second attachment bore of the pin.

A milling cutter head intended primarily for aluminum machining comprises grooves (4) in which are mounted cutting insert-carrying cartridges (2) and spacer plates (3). Those sides of the cartridge and the spacer plate that are in contact are serrated in the same direction. The other side of the spacer plate and the side surface of the groove being in contact with it are serrated in a direction which is perpendicular to the first mentioned serration. In this way it is possible to independently of each other and precisely adjust the cutting edge both axially and radially.

2.1. Bekannte Messerköpfe neigen bei hohen Drehzahlen bedingt durch die auftretenden Zentrifugalkräfte zu Aufweitungen, wodurch sich die Lage der Schneidkanten der Schneidplattenträger verändern kann. Es ist das Ziel der Erfinding, einen auch bei hohen Drehgeschwindigkeiten maßgenau einjustierbaren Messerkopf zu schaffen. 2.2. Erfindungsgemäß weist der Spannkeil 13 eine windschief angeordnete Keilfläche 21b auf, welche mit einer Kontaktfläche 21a des Schneidplattenträgers 2 zur Anlage bringbar ist, um diesen in die Nut 20 des Grundkörpers 1 vorzuspannen. Erfindungsgemäß ist auch vorgeschlagen, eine Keilprismenanordnung 10 zur radialen Vorspannung des Schneidplattenträgers 2 relativ zum Grundkörper 1 vorzusehen.

Die Erfindung bezieht sich auf einen Messerkopf mit einem im wesentlichen zylindrischen Grundkörper und mehre ren an dessen Umfangsbereich angeordneten, auswechselba ren, in axialer und radialer Richtung des Grundkörpers minde stens eine Schneide aufweisenden Schneidkörpern. Zur Errei chung einer betriebssicheren, kleinste Toleranzen ermögli chenden dreidimensionalen Einstellung des Schneidkörpers ist jeder der Schneidkörper an einem am Grundkörper gehal terten Trägerteil gelagert, welches mittels separater, zwischen Grundkörper und Trägerteil angeordneter Verstelleinrichtun gen radial und axial zum Grundkörper verstellbar und mittels einer Spanneinrichtung an diesen fixierbar ist.

A milling cutter which is adapted to be rotated about a central axis includes at least one insert pocket having opposed leading and trailing walls, as well as a rear wall. An indexable insert having front and rear planar surfaces is receivable in the insert pocket, along with at least one locking wedge, which is interposed between the insert and the pocket walls for securing the insert within the pocket. In accordance with the subject invention, an adjustable locating wedge is provided for regulating the axial location of the insert. The locating wedge, a portion of which is disposed in abutting relationship with the axially lowermost cutting edge of the insert, is received within a groove located in the rear wall of the insert pocket. The receiving groove is aligned with the insert and extends radially inwardly from the periphery of the cutter body. In addition, the receiving groove is disposed at an angle relative to the rear wall of the insert pocket such that as the position of the adjustable locking wedge is varied within the groove, its axial position relative to the cutter body is also varied. By this arrangement, the axial position of the insert, which rests on the locating wedge, can be adjusted. More specifically, as the position of the locating wedge is varied within the groove, its axial position is varied, thereby varying the axial position of the insert. In a preferred embodiment, an adjustable insert seat is provided to vary the radial position of the insert.
