CUTTING TOOL HAVING COOLANT DELIVERY SYSTEM FOR PROVIDING CUTTING FLUID IN A FAN-LIKE PATTERN

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).
