摘要： The invention relates to a superfinishing tool having a shank (2), as well as at least one rigid cutting edge (16) and at least one guide rib (30) on the periphery. In addition, or alternatively, the cutting edge (16) and/or the guide rib(s) (30) can be configured to form a single-piece solid tool with the shank (2). The guide beads or ribs guarantee steady, stable functioning of the tool in spite of high rotational speed and/or hardness of the workpiece. An additional advantage is provided by producing the tool as a solid tool, i.e. made of solid hard metal.

摘要： The invention relates to an expandable reamer having a base body (3), a ring section (R), at least one cutting edge (13, 15, 13', 15') which is geometrically defined and provided on the outer surface of the ring section (R), an adjustment device (21) which works on the ring section (R) from the inside, has an adjustment screw (23), and serves to adjust the radial position of the at least one cutting edge (13, 15, 13', 15'), wherein the adjustment device (21) is arranged in a cavity (7) provided in the base body (3) of the expandable reamer (1), and an adjustment body with a conical or round outer surface (49). The adjustment body can be displaced in the direction of the central axis (39) of the expandable reamer (1) and serves for the expansion of the ring section (R). The expandable reamer (1) is characterized in that the adjustment body is designed as an adjustment sleeve (25) which surrounds the adjustment screw (23) and is mounted in a floating manner.

摘要： Es wird eine Dehnreibahle mit
- einem Grundkörper (3),
- einem Ringabschnitt (R),
- mindestens einer auf der Außenfläche des Ringabschnitts (R) vorgesehenen geometrisch definierten Schneide (13,15, 13',15'),
- mit einer auf den Ringabschnitt (R) von Innen wirkenden, eine Stellschraube (23) umfassenden Stelleinrichtung (21) zur Einstellung der radialen Position der mindestens einen Schneide (13,15,13',15'), wobei
- die Stelleinrichtung (21) in einem dem Grundkörper (3) der Dehnreibahle (1) vorgesehenen Hohlraum (7) angeordnet ist, und einen Stellkörper mit einer konischen oder balligen Außenfläche (49) aufweist, der in Richtung der Mittelachse (39) der Dehnreibahle (1) verlagerbar ist und der Aufweitung des Ringabschnitts (R) dient,
vorgeschlagen. Die Dehnreibahle (1) zeichnet sich dadurch aus, dass
- der Stellkörper als Stellhülse (25) ausgebildet ist, welche die Stellschraube (23) umgibt und auf dieser schwimmend gelagert ist.摘要翻译： 可扩展铰刀（1）具有基本体（3），环形部分（R），几何形状地限定并设置在环形部分的外表面上的切割刃（13,15）。 调节装置（21）从内部工作在环形部分上，具有调节切割刃的径向位置的调节螺钉（23）。 调节装置布置在设置在可扩展铰刀的基体中的空腔（7）中并且具有锥形或圆形的外表面（49）。

摘要： A rotary cutting tool (20) for reaming operations, including a generally cylindrically shaped tool shank (22) with a longitudinal axis (Al) having a plurality of radially protruding and generally axially extending clamping wings (38), and a cylindrically shaped cutting head (24) having a central bore (58) and a plurality of axially extending cutting edges (62) with an outer cutting diameter (D). The central bore (58) has a plurality of circumferentially and alternately spaced bore sectors (70) and bore recesses (72), where each bore sector (70) has an outwardly inclined female clamping surface (74) in clamping contact with an outwardly inclined male clamping surface (40) of each clamping wing (38). A cylindrical shaped locking sleeve (26) and a cylindrical shaped clamping nut (28) assembled to the tool shank (22) provide a means to adjust the clamping contact forces and the cutting diameter (D) of the cutting head (24), and also enable removal and replacement of the cutting head without removal of the locking sleeve (26) and clampingnut (28).
