    摘要： A tool holder assembly (10) that includes a tool holder member adapted to be secured to a machine tool and a cutting insert support/clamp (10b) for clamping and supporting a cutting insert (12). The support/clamp member includes a plurality of serrations (80) that are engageable with complementally formed serriions (82) on the tool holder whereby a tight fitting engagement is achieved using removable fasteners (16). The support/clamp includes a clamping arm (26)elastically movable towards and away from a support base and a clamping block (52) connected to the connecting arm adapted to receive clamping forces from a threaded clamping bolt (50). The clamping bolt (50) defines a force applying surface (62a) located in a first plane whereas the clamping block defines a force receiving surface (60a) located in a second plane, the first and second planes located at a diverging angle with respect to each other. The clamping block (52)includes an edge portion (79) engageable with a step (78) on the tool holder that is spaced from the clamping arm. The diverging planes and the engagement of the clamping block with the stepped portion increases the force applied by the clamping arm to the cutting insert for a given adjustment of the clamping bolt and resists rollover of the insert.

    摘要： The present invention relates to cutting tool inserts, wherein an abrasive tip comprising a hard material, an abrasive or superabrasive material, is bonded to an insert body by mechanical forces, said mechanical forces being generated through deformation of mating geometric features on the abrasive tip and insert body. The present invention is also directed to a method for forming a cutting tool insert. The method includes providing an abrasive tip and an insert body, each having mating geometrical features. The abrasive tip is then joined to the insert body through the respective mating geometrical features causing a deformation in at least one of the mating features. The deformation provides mechanical forces sufficient to hold the abrasive tip in the insert body.

    摘要： The present invention relates to a tool head for a chip metal working tool having a cutting insert (3), comprising a basic holder (1) and an integral insert holder (4), the forward portion of which is provided with an insert pocket between a lower support portion (6) and an upper clamp portion (5) wherein the upper clamp portion (5) is actuatable by a press device. The characteristics is that the press diveice is in the shape of a clamp screw (19) with a conical head (18) that is received in a recess in the basic holder (1) and arranged to be subjected to displacement in its axial direction such that its conical head (18) upon insertion in a slit (20) spaced from the insert pocket achieves such bending outwardly of the upper portion of the basic holder such that thanks to its movement a clamping of the insert occurs.
