摘要： A cutting tool (10) includes a body (12) having a forward end (14) and a rearward end (16). The forward end includes an insert-receiving pocket (20a, 20b). The body further includes a coolant delivery system (70) comprising a main coolant passage (72) having a main coolant inlet (74) extending from the rearward end toward the forward end, a primary coolant passage (76) in fluid communication with the main coolant passage and having a primary coolant outlet (78) exiting from the insert-receiving pocket, and a secondary coolant passage (80) in fluid communication with the primary coolant passage and having a secondary coolant outlet (82). The primary coolant outlet intersects the secondary coolant outlet to form an outlet (84) having a substantially non-circular shape. As a result, the fluid exiting the outlet (84) is in a fan-like pattern and is evenly distributed over the cutting edge (54, 56, 58, 60).

摘要： A clamping tool holder (10) includes a tool holder body (12) and a clamp (10) for clamping a cutting insert (22). The clamp (40) causes the cutting insert (22) to press against the bottom and the side walls of an insert-receiving pocket (14) of the tool holder body (12). 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. When a clamp screw (52) is tightened, a nub (48) of the clamp (40) engages only an inside rearward surface of a mounting bore (24) of the insert and the top surface (22a) of the cutting insert (22). In addition, only a forward lower face (46a) of a head portion of the clamp screw (52) engages a top surface (22a) of the clamp (40).
摘要翻译：夹紧工具夹具（10）包括工具夹具主体（12）和用于夹紧切削刀片（22）的夹具（10）。夹具（40）使切削刀片（22）压靠工具架主体（12）的刀片接收凹座（14）的底部和侧壁。刀架本体（12）具有倾斜表面（34），所述倾斜表面（34）在远离刀片接收凹部（14）的方向上向内倾斜。夹具（40）具有倾斜表面（50），倾斜表面（50）用作与工具架主体（12）的倾斜表面（34）的斜面。导向销（60）防止夹具（40）在夹紧或拧松过程中扭曲。当夹紧螺钉（52）被拧紧时，夹具（40）的凸块（48）仅与嵌件的安装孔（24）的内侧后表面和切削嵌入件（22）的顶表面）。另外，只有夹紧螺钉（52）的头部的向前的下表面（46a）接合夹具（40）的顶表面（22a）。
