Reducer Sleeve Coolant Delivery for Cutting Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reducer sleeves do not provide coolant delivery features to cutting tools without internal coolant channels, limiting their effectiveness in tools like end mills and drills, and fail to deliver coolant along the entire length of the cutting section under sufficient pressure.
Innovation Solution
The design of a reducer sleeve with a flange and nozzles that create a coolant flow path, allowing coolant to be delivered to multiple cutting zones along the entire length of the cutting tool, providing a fluid-tight seal and adequate pressure through a system of troughs and nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional reducer sleeves are used without internal coolant channels, then the device complexity is reduced and ease of manufacture is improved, but coolant delivery capability to cutting tools is lost
Solution Approach 1:
The patent introduces an intermediary coolant delivery system consisting of a coolant delivery channel within the reducer sleeve body and a coolant delivery nozzle positioned at the forward end. This intermediary structure enables coolant to be delivered from the reducer sleeve to the cutting tool, resolving the contradiction by adding a dedicated coolant delivery mechanism rather than requiring complex internal channels within the cutting tool itself.
Solution Approach 2:
The reducer sleeve is designed to provide its own coolant delivery capability through integrated coolant channels and nozzles, allowing it to serve itself and the cutting tool without requiring the cutting tool to have internal coolant channels. This self-service approach maintains ease of manufacture for simple cutting tools while ensuring reliable coolant delivery.
2Reliability
If coolant is delivered only to the forward end of the cutting tool, then the device complexity is minimized, but the coolant delivery coverage along the cutting section is insufficient
Solution Approach 1:
The coolant delivery system is segmented into multiple delivery nozzles positioned at different locations along the forward end of the reducer sleeve, with each nozzle directing coolant to different zones of the cutting tool. This segmentation allows coolant to reach multiple cutting zones simultaneously without requiring complex internal channeling within the cutting tool, thus improving coverage while maintaining relative simplicity.
Solution Approach 2:
The patent extends coolant delivery from a single point to multiple points along the axial dimension of the cutting tool by positioning multiple nozzles at different radial distances from the longitudinal axis. This dimensional expansion allows coolant to reach different cutting zones along the length of the cutting tool, improving coverage without proportionally increasing complexity.
3Ease of operation
If coolant pressure is not maintained at sufficient levels, then the ease of operation is improved with lower system requirements, but the effectiveness of coolant delivery to the cutting tool is reduced
Solution Approach 1:
The patent utilizes hydraulic principles by designing a closed coolant delivery channel system within the reducer sleeve that maintains coolant pressure throughout the delivery path. The channel configuration and nozzle positioning work together to deliver coolant at sufficient pressure directly to the cutting zones, ensuring effective coolant delivery while operating within standard hydraulic system parameters.

AI summary
Reducer sleeves are described herein. Reducer sleeves described herein comprise a reducer sleeve body having an axial forward end and an axial rearward end. The reducer sleeve body defines a longitudinal axis. Reducer sleeves further comprise a flange disposed at the axial forward end of the reducer sleeve body. The flange defines a first nozzle disposed at a first radial distance from the longitudinal axis and a second nozzle disposed at a second distance from the longitudinal axis. The reducer sleeve body defines a first trough extending from the axial rearward end to the axial forward end. The first trough is in communication with the first nozzle and the second nozzle, whereby coolant is able to enter the first trough and flow along the first trough and into the first nozzle and the second nozzle such that the coolant is ejected by the first nozzle and the second nozzle.
