摘要:
A cutting tool comprising a cutting tool holder and a cutting insert adapted to be mounted thereon. The tool holder comprises an insert seat defined by a base and at least one side wall extending from the base to define an insert seat space adapted to receive therein the insert. The seat comprises a support element extending into the insert seat from the base, and a fastening member engageable with the seat. The fastening member is displaceable with respect thereto between a mounting position adapted to allow the insert to be mounted onto the seat and a securing position adapted for securing the insert within the seat. The insert is formed with a securing cavity and when the insert is mounted onto the tool holder and is in the securing position, a portion of the support element and the fastening member is received within the cavity of the insert.

Beschrieben wird eine Spann- und Justiervorrichtung für ein Zerspanungswerkzeug, wobei ein plattenförmiger Schneideinsatz (2) mittels einer Vorspann- und Fixiereinrichtung, insbesondere einer Spannschraube (4), mit seiner Bodenfläche (20) gegen eine Sitzfläche (30) derart vorspann- und fixierbar ist, dass er sich mit den Seitenwandabschnitten (22,24) lagefixiert an einem Schneidenträger (3) abstützt. Zwischen Schneidenträger und Schneideinsatz befindet sich eine Verstellvorrichtung, die mittels einer Druckschraube (10) verstellbar ist. Die Verstellvorrichtung, bestehend aus einem Antriebskeil (15) und einem Verstellkeil (12), wird über eine Druckschraube verstellt. Die Druckschraube wirkt auf den Antriebskeil, über den der Verstellkeil angetrieben wird. Durch den antreibbaren Verstellkeil, der formschlüssig und verschiebbar im Schneidenträger aufgenommen ist, lässt sich der Schneideinsatz verstellen.

The disclosure provides a device for adjusting a position of a cutting insert, the device may include an adjustment screw, an adjustment wedge adapted to receive the screw, wherein a position of the wedge is a function of the rotation of the screw and a partially flexible intermediate member between a surface of the wedge and a surface of the cutting insert, wherein the intermediate member is supported on both ends. The disclosure further provides a cutting tool adapted to receive at least one device for adjusting a position of a cutting insert, wherein the device may include an adjustment screw, an adjustment wedge adapted to receive the screw, wherein a position of the wedge is a function of the rotation of the screw and a partially flexible intermediate member between a surface of the wedge and a surface of the cutting insert, wherein the intermediate member is supported on both ends.
摘要:
In a cutting tool for chip removing machining a holder (2) for a cutter (4') has a body (10) received therein and movable with surfaces to bear against the cutter for defining the position of the cutter in the direction of an intended axis of rotation of the holder as well as a screw (9) which may be screwed in a threaded bore (8) in the holder. Spring members (14) are arranged to act between the holder (2) and the body (10) for biasing the body against said screw portions (11 ).
