Directional Coolant Ring for Small Cutting Tool Lubrication

The patent implements internal coolant channels nested within the tool body structure, allowing coolant to be delivered from the inside of the tool rather than externally. This nesting approach enables the coolant to reach the cutting zone more effectively by traveling through the tool's internal pathways and exiting through outlets positioned at or near the cutting edges, thereby improving lubrication effectiveness while controlling cutting temperature.

The patent introduces coolant channels as an intermediary mechanism between the coolant source and the cutting zone. These channels act as conduits that transport and direct the coolant flow precisely to where it is needed, mediating the delivery process to ensure effective lubrication and cooling at the cutting edges rather than relying on external coolant application.

The patent integrates coolant channels and outlets within the tool body structure, positioning outlets at or near the cutting edges. This nested configuration enables coolant to flow directly through the cutting zone, effectively carrying chips away from the cutting area. The internal channel system allows coolant to reach chips at their source, improving evacuation efficiency and preventing chip recutting that degrades surface finish.

The coolant channels serve as intermediary pathways that facilitate chip evacuation by transporting coolant directly to the chip formation zone. The channels mediate the interaction between coolant and chips, enabling efficient chip removal through the tool's internal flow paths rather than relying on external coolant application that cannot effectively reach and evacuate chips from the cutting zone.

The patent implements local quality by positioning coolant outlets specifically at or near the cutting edges rather than uniformly distributing them or placing them only in flutes. This localized outlet placement ensures that even in small tools under 6 mm, the coolant is delivered precisely where needed for effective lubrication. The design adapts the outlet configuration to the specific geometric constraints of small tool dimensions while maintaining lubrication effectiveness.

The patent nests the coolant delivery system within the tool body, with channels and outlets integrated into the tool's internal structure. This nested approach allows effective lubrication implementation in small tools by efficiently utilizing the limited space available in tools under 6 mm, avoiding the need for external coolant systems that are impractical for such small dimensions.

The patent employs asymmetric coolant channel configuration, with channels and outlets positioned and oriented to direct coolant flow specifically toward the cutting part rather than uniformly distributing it. The outlets are strategically placed at or near the cutting edges with orientations that channel the coolant flow in the desired direction, creating an asymmetric but optimized lubrication pattern that ensures sufficient lubricant directionality to the cutting zone.

The coolant channels act as intermediary structures that guide and direct the coolant flow toward the cutting part. These channels mediate the coolant's path, ensuring it is sufficiently directed to the cutting zone rather than dispersing randomly. The channel geometry and outlet positioning serve as intermediaries that control flow directionality to achieve effective lubrication at the cutting edges.
