A material removal (10) having a plurality of cartridges (14) mounted on an active portion (I) where a plurality of seating members (18) mounted in each of the plurality of cartridges (14) pivots about an axis between a retracted position and an extended position is disclosed. Alternative embodiments have a single pivotable seating member (18). The pivotable extending seating members (18) operate to extend and retract in a scissors-like motion and enable compact and efficient machining operation, particularly for crank shaft bearing supports.

[Task] To provide an insert which is attached to a tool body of a hole machining tool, which can enhance movement balance and rigidity of the tool body by reducing portions cut out from the tool body, and which can simply adjust the position of the insert with high precision. [Means for Resolution] In an insert 50 attached to a hole machining tool having an attachment seat 31 and a pressing member 40 for pressing the insert 50 to adjust the position of a peripheral cutting edge in a diameter direction, the insert has a panel shape, one surface of the insert in the thickness direction becomes a seating surface 51, the other surface in the thickness direction becomes a peripheral flank surface 52, the surface facing the rear side in a tool rotation direction becomes a pressed surface 61 in a state that the insert is attached to the attachment seat 31, the side surface facing the front side in the tool rotation direction becomes an inclined surface 54, and a peripheral cutting edge is formed at a ridge portion on the outside of the inclined surface 54 in the diameter direction.

A cutting tool assembly (1) including a cutter body (3) having a cutting unit receiving pocket (7) for releasably receiving a cutting unit (8) with an operative cutting edge (10) and an abutment surface (13) remote therefrom. An elongated bore (15) adapted for receiving an adjustment device (19) is formed in the cutter body, the bore opening into the receiving pocket adjacent the abutment surface. The adjustment device includes an elongated tubular adjustment member (22) having a longitudinally directed adjustment surface (26) inclined with respect to its longitudinal axis (23), an elongated adjustment screw (27) initially slidingly extending through the adjustment member and adjustment member inter-engaging means for securing the adjustment member on the adjustment screw. On screwing the adjustment screw in a given direction, the adjustment member pushes the cutting unit outward.

The present invention relates to an adjustable reamer (10), which comprises a securing portion (11), a shank (12), guide members (24,25), at least one cutting insert (14), adjustment means (36,37,38,39) and clamping means (27,40), wherein a first clamping means (27) is releaseable from the shank. A first place of contact provided between the first clamping means (27) and the shank (12) and a second place of contact is provided between the first the clamping means (27) and the cutting insert (14). A first angle between the first and second places of contact in relation to the rotational axis (CL) of the reamer is at least 100°, preferably larger than 135°.

Adjustable cutting tool bit support (11), usable as in a stump cutter body, including adjustable jack for variable registration depth of cutting bit, a differential screw (14) engaging differential threads in the body and jack (13) for adjusting the jack position, a wedge clamp (15) for locking engagement of the body (11) and tool bit in adjusted position and a differential screw (16) engaging differential threads in the respective wedge clamp (15) and jack (13) for positively moving said wedge clamp (15) into an effective clamping engagement.
摘要:
A boring cutter which is adapted to be rotated about its central axis includes at least one insert pocket having opposed parallel leading and trailing walls, as well as a bottom wall. An insert seat of generally L-shaped configuration is provided, with the leading surface of the insert seat being in abutting relationship with the leading wall of the pocket. The opposed trailing surface of the insert seat includes both a leading and rear locating support surface adapted to receive an indexable cutting insert. A wedge is receivable between the rear surface of the cutting insert and the trailing wall of the pocket. The radial position of both the insert seat and the wedge, relative to the central axis of the boring cutter is adjustable. By this arrangement, the radial position of the cutting insert may be varied to thereby adjust the effective outer diameter of the boring cutter. In addition, the amount of overhang, or the difference in the radial position between the cutting insert and the wedge, remains constant thereby maintaining the structural support for the cutting edge of the insert.
摘要:
Um bei einem Werkzeug (4) eine Feineinstellung der radialen Position einer Schneidplatte (2A,B) zu ermöglichen, wird bei einem Werkzeuggrundkörper (14), der einen Plattensitz zur unmittelbaren Befestigung der Schneidplatten (2A,B) aufweist, eine rückseitige Anlagewand für die Schneidplatten (2A,B) als ein elastisch gehaltener Steg (22) ausgebildet. Hierzu wird in den Werkzeuggrundkörper (14) ein Spreizschlitz (26) eingebracht derart, dass der Steg (22) lediglich noch an einer Befestigungsseite (24) mit dem restlichen Werkzeuggrundkörper (14) verbunden ist. In den Spreizschlitz (26) ist eine Einstellschraube (28) zur Feineinstellung einschraubbar. Diese Ausgestaltung erlaubt einen kompakten Aufbau und führt nur zu einer geringen Beeinträchtigung der Stabilität des Werkzeuggrundkörpers (14). Der Feineinstellmechanismus ist daher insbesondere auch bei kleinen Werkzeugen einsetzbar.
