    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： A cutting tool holder blade (100,101) is formed of hard metal such as cemented carbide, the cutting tool holder blade (100,101) having a front plane (F), a perpendicular mid-plane (P). An insert pocket (104) of the holder blade (100,101) has a base jaw (106) and a clamping jaw (110) resiliently connected to the base jaw (106) in a unitary one piece construction. The base jaw (106) has a base jaw abutment surface (108) and the clamping jaw (110) has a clamping surface (112) facing opposite the base jaw abutment surface (108), and an insert stop surface (114). A curved inner surface (116) extends from the base jaw abutment surface(108) towards and along the clamping jaw (110), the curved inner surface (116) having a front extremity portion (118). The clamping jaw (110) is narrowed down adjacent the front extremity portion (118), such that the clamping surface (112) overhangs the front extremity portion (118) of the curved inner surface (116), in a direction towards the base jaw (106) and away from the front plane (F).

    摘要： A clamping tool holder (10, 100) includes a tool holder body (12) and a clamp (40) for clamping a cutting insert (22). The tool holder body (12) has an inclined surface (34) sloping inward in a direction away from the insert-receiving pocket (14). The clamp (40) has an inclined surface (50) that acts as a ramp with the inclined surface (34) of the tool holder body (12). A guide pin (60) prevents the clamp (40) from twisting during tightening or loosening of the clamp (40). When a clamp screw (52) is tightened, a nub (48) of the clamp (40) engages an inside rearward surface of a mounting bore (24) of the insert (22) along a line of contact (48a) and exerts a force downward and rearward on the insert (22).

    摘要： An apparatus for releasably holding a tubular toolholder shank includes a tool support member; a canister disposed within the tool support member; a lock rod movable within the tool support member in a reciprocating motion for pulling the tubular toolholder shank into a locked position and for releasing the tubular toolholder shank to an unlocked position; and at least two locking elements engaging the lock rod so that movement of the lock rod causes the locking elements to extend outward to engage the tubular toolholder shank. The lock rod includes a relief cavity extending rearward from a forward end of the lock rod. The lock rod has a maximum outer diameter and the relief cavity has a maximum diameter. A ratio of the maximum diameter of the relief cavity to the maximum outer diameter of the front portion of the lock rod is greater than approximately 1 to 4.

    摘要： The invention relates to a cutting tool of the type that comprises a replaceable cutting insert (2) and a basic body (1), which includes a rear fixing part (5), a front supporting part (6), and a tightening part (7) situated over the support part. The tightening part (7) is spaced-apart from the two other parts (5, 6) via two gaps (8, 9) and connected to the rest of the basic body via elastic material portions (26) that form a joint for the tightening part. In such a way, the tightening part can be pivoted and clamp the cutting insert by means of a tightening element (27). In a known way, the fixing part (5) comprises an internal channel (13) for feed of a cooling liquid or fluid in the forward direction through the basic body (1). According to the invention, the channel (13) extends into a second channel (32) inside the tightening part (7) via a channel section (33) that is entirely or partly housed in a bridge (28), which, like the joint, is formed of the material in the basic body, and which bridges one (9) of the two gaps. In a second aspect, the invention also relates to a basic body for cutting tools of the kind in question.
