摘要： A clamping apparatus (35) for detachably connecting a tool unit (10) to a tool supporter (37) with increased holding force is provided. The clamping apparatus (35) includes a housing (41), a pair of opposing locking spheres (57a, b) within the housing (41), a cylindrical canister member (39) mounted within the housing (41) that is matable with an insert-supporting tool unit (10) and which has a pair of opposing apertures (55a, b) in its sidewalls for conducting the locking spheres (57a, b) from a locking to an unlocking position, and a lock rod (60) reciprocally movable within the interior of the canister member (39) along an axis (A) and having opposing cam portions (64a, b) for radially moving the locking spheres (57a, b) through the canister apertures (55a, b) into wedging engagement with opposing angled walls (30) of sphere receiving openings (20) in the tool unit (10). To increase the mechanical advantage of the wedging action between the locking spheres (57a, b) and the angled walls (30) of the tool unit (10), the aperture walls (56) of the canister member (39) are angled with respect to a line (R) extending radially from the lock rod axis (A) to reduce the angle between the aperture wall (56) and the tool unit wall (30). Such angling increases the force of wedging and locking engagement between the locking spheres (57a, b) and the angled walls (30) of the tool unit (10). In the preferred embodiment, the aperture walls (56) are angled 15 DEG with respect to the aforementioned radial line (R), thereby increasing the holding force of the clamping mechanism (35) by 30 %.
摘要翻译：提供了一种用于以增加的保持力将工具单元（10）可拆卸地连接到工具支撑件（37）的夹紧装置（35）。夹紧装置（35）包括壳体（41），壳体（41）内的一对相对的锁定球体（57a，b）;安装在壳体（41）内的圆柱形罐构件（39）插入支撑工具单元（10），并且在其侧壁中具有一对相对的孔（55a，b），用于将锁定球体（57a，b）从锁定位置解锁到解锁位置，以及锁定杆（60）可沿着轴线（A）在罐构件（39）的内部移动并且具有用于使锁定球体（57a，b）通过罐孔（55a，b）径向移动的相对的凸轮部分（64a，b）成为楔入接合在工具单元（10）中具有球体接收开口（20）的相对的倾斜壁（30）。为了增加锁定球体（57a，b）和工具单元（10）的倾斜壁（30）之间的楔入动作的机械优点，罐构件（39）的孔壁（56）相对于到从锁定杆轴线（A）径向延伸的线（R），以减小孔壁（56）和工具单元壁（30）之间的角度。这种角度增加了锁定球体（57a，b）与工具单元（10）的倾斜壁（30）之间的楔入和锁定接合的力。在优选实施例中，孔壁（56）相对于上述径向线（R）成15°角度，从而将夹紧机构（35）的夹持力增加30％。

摘要： A cutting insert (1) having a chipbreaking configuration for effectively embrittling and breaking thin, foil-like chips (61) produced by drilling or other fine-cutting operations is provided. The cutting insert (1) includes a polygonal insert body (3) having a top surface (5), a side relief surface (9), and a cutting edge (11) defined therebetween, and a chipbreaker (23) formed by an elongated groove (25) disposed on the top surface (5) behind the cutting edge (11) in combination with a plurality of recesses (27) disposed over the groove (25) having opposing side edges (43). The back wall (34) of the groove (25) applies curling forces to the chips (61), while the opposing side edges (43) of the recesses (27) engage and corrugate the chips (61) thereby embrittling them by work-hardening. The corrugated chips are broken by the curling forces applied by the back (34) and rear (42) walls of the groove (25) and the recesses (27) into small pieces that are easily expelled from the vicinity of the cutting operation.

摘要： A diamond-coated tool (80) and a process for making it. The process includes a sintering step. In that step, the tool substrate is sintered in an atmosphere and for a time and at a temperature so that superficial, exaggerated grain growth is promoted that imparts a surface roughness which may serve as anchoring sites during a subsequent diamond coating step which is performed by a vapor deposition technique. The diamond-coated tool includes a large grain substrate surface, and a high bond strength between the diamond coating and the substrate surface.
