  • Patent number: 8079785
    Abstract: A tool holder assembly that includes a tool holder member adapted to be secured to a machine tool and a cutting insert support/clamp for clamping and supporting a cutting insert. The support/clamp member includes a plurality of serrations that are engageable with complementally formed serrations on the tool holder whereby a tight fitting engagement is achieved using removable fasteners. The support/clamp includes a clamping arm elastically movable towards and away from a support base and a clamping block connected to the connecting arm adapted to receive clamping forces from a threaded clamping bolt. The clamping bolt defines a force applying surface located in a first plane whereas the clamping block defines a force receiving surface located in a second plane, the first and second planes located at a diverging angle with respect to each other. The clamping block includes an edge portion engageable with a step on the tool holder that is spaced from the clamping arm.

  • Publication number: 20080253847
    Abstract: An adjustable threading tool assembly. A cutting insert holder is adjustably held in a pocket in a toolholder. The cutting angle of the insert can be set by selecting a precision ground washer that sets the position of a retaining bolt that holds the insert in the pocket such that the desired angle is provided.

  • Patent number: 7331736
    Abstract: A cutting tool assembly (14) including a tool holder (20) having a removeable clamp (20a). A cutting insert support blade member (16) is removably held in the tool holder by the clamp (20a). The cutting insert support blade (16) includes at least one, preferably two, insert receiving pockets (30). The pockets (30) are defined by a body portion (16b) and a clamp portion (16a) joined together by an integrally formed resilient or deformable portion (16c) which permits slight resilient movement between the clamping and body portions to facilitate the installation of a cutting insert (18) in a pocket. When the insert support blade (16) is mounted in the tool holder (20), the clamp inserts clamping forces to the clamping portion (16a) of the insert support blade which serves to secure the insert support blade to the tool holder and exert clamping forces on an insert (18) held in the pocket.
