Adaptor Fluid Path for Cutting Head Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many cutting tools, especially those secured with screws, lack a fluid passage, preventing the effective use of cooling or chip-removal fluids due to the screw obstructing the fluid flow to the cutting region.
Innovation Solution
An adaptor is designed to provide a fluid path through the tool holder and nozzle, allowing cooling fluids or gases to reach the cutting inserts by creating a channel that bypasses the screw, enabling efficient cooling and chip removal during machining operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a screw is used to secure the cutting head to the tool holder, then the cutting head is firmly fixed, but the screw obstructs the fluid flow path to the cutting region
Solution Approach 1:
The screw is divided into two functional parts: a solid portion for mechanical fastening and a hollow tubular portion for fluid conduction. This segmentation allows the screw to simultaneously provide structural support and fluid flow path, resolving the contradiction between fixing strength and fluid flow obstruction.
Solution Approach 2:
The screw is designed to perform multiple functions: it acts as both a fastening element (providing mechanical strength to secure the cutting head) and a fluid conduit (allowing cooling or chip-removal fluid to pass through). This multi-functionality eliminates the need for separate fluid passages while maintaining secure fixation.
2Object-generated harmful factors
If a hollow tubular screw with internal cavity is used, then fluid can pass through the screw, but the screw head structure becomes more complex requiring a distributor device
Solution Approach 1:
The distributor device is merged with the screw head by integrating the fluid distribution function directly into the screw structure. The hollow tubular screw head incorporates internal passages that distribute fluid radially outward to multiple cutting inserts, eliminating the need for separate distributor components and reducing overall device complexity.

AI summary
An adaptor (20, 76, 104, 106) secures a cutting head (16) to a tool holder (12, 14) having a passage for fluid. The adaptor (20, 76, 104, 106) has a corresponding passage (68, 94) for fluid to which a nozzle (22) is connected for the distribution of fluid towards a cutting region (54) of the cutting head (16).
