Abstract
A coolant bonnet for a cutting tool includes a head portion, a shank portion, an internal coolant passage extending through the shank portion and into a coolant manifold disposed within the head portion, and one or more coolant ducts extending radially outward from the manifold to an outlet port. Each coolant duct is aligned with the chip flutes of the cutting tool and directs coolant at a predetermined exit angle in an axially rearward direction toward the cutting edges of a cutting insert mounted on the cutting tool. A method of providing coolant to a cutting edge of a cutting insert mounted on the cutting tool is also disclosed.
Claims18
A coolant bonnet for a cutting tool, comprising:
- a head portion;
- a shank portion;
- an internal coolant passage extending through the shank portion and into a coolant manifold disposed within the head portion;
- and
- one or more coolant ducts extending radially outward extending from the coolant manifold to an outlet port, each coolant duct in fluid communication with the coolant manifold,
- wherein a portion of the one or more coolant ducts is non-linear;
- and
- wherein each coolant duct directs coolant at a predetermined exit angle with respect to a central, longitudinal axis of the coolant bonnet in an axially rearward direction toward the cutting tool.
A combination cutting tool and coolant bonnet, comprising:
- a cutting tool, comprising:
- a cutting portion having a forward end and a rearward end and a peripheral surface therebetween, the cutting portion including a chip flute that extends rearwardly from the forward end;
- and a cutting insert mounted on the cutting portion;
- and
- a coolant bonnet mounted onto the cutting tool, the coolant bonnet comprising:
- a head portion;
- a shank portion;
- an internal coolant passage extending through the shank portion and into a coolant manifold disposed within the head portion;
- and
- one or more coolant ducts extending radially outward extending from the coolant manifold to an outlet port, each coolant duct in fluid communication with the coolant manifold,
- wherein a portion of the one or more coolant ducts is non-linear;
- and
- wherein each coolant duct directs coolant at a predetermined exit angle with respect to a central, longitudinal axis of the coolant bonnet in an axially rearward direction toward the cutting insert of the cutting tool.
A coolant bonnet for a cutting tool, comprising:
- a head portion having a top surface and a bottom surface, the top surface defined by a wave-like topography comprising a plurality of crests separated by troughs;
- a shank portion;
- an internal coolant passage extending through the shank portion and into a coolant manifold disposed within the head portion;
- and
- one or more coolant ducts extending radially outward from the manifold, through a respective crest, to an outlet port, each coolant duct in fluid communication with the coolant manifold,
- wherein each coolant duct directs coolant at a predetermined exit angle with respect to a central, longitudinal axis of the coolant bonnet in an axially rearward direction toward the cutting tool.
