Cutting Insert Coolant Channel Layout for Rotary Tool Holders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools with interchangeable cutting arrangements face challenges in efficiently supplying coolant and/or lubricant to the cutting arrangements, particularly in rotary tools where traditional methods may not effectively address the unique operational challenges.
Innovation Solution
The tool design incorporates a holder with integrated medium channels that connect to corresponding channels within the cutting arrangements, allowing for the efficient distribution of coolant and/or lubricant directly to the cutting edges via lateral surfaces, which are often clearance surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional coolant supply methods are used in rotary tools with interchangeable cutting arrangements, then the tool design remains simple, but the coolant supply efficiency to cutting arrangements deteriorates
Solution Approach 1:
The coolant supply system is segmented into two parts: a first medium channel in the holder and a second medium channel in the cutting arrangement. This segmentation allows the cutting arrangement to have its own dedicated coolant channel that can be efficiently supplied from the holder, improving coolant supply efficiency without significantly complicating the overall tool design.
Solution Approach 2:
The second medium channel in the cutting arrangement is nested within or connected to the first medium channel in the holder. The cutting arrangement with its integrated medium channel is positioned within the holder structure, creating a nested configuration that improves coolant delivery while maintaining compact tool design.
2Reliability
If coolant channels are incorporated into the holder to supply coolant to cutting arrangements, then coolant supply is improved, but the holder structure becomes more complex
Solution Approach 1:
The coolant channel system is divided between the holder (first medium channel) and the cutting arrangement (second medium channel). This segmentation allows the holder to have a simpler, more straightforward channel design while the cutting arrangement carries its own channel, reducing the complexity burden on the holder structure.
Solution Approach 2:
The cutting arrangement is equipped with its own second medium channel that it uses to supply coolant to itself. This self-service approach eliminates the need for complex coolant distribution pathways in the holder, as each cutting arrangement independently manages its own coolant supply through its integrated channel.
3Adaptability or versatility
If interchangeable cutting arrangements are used, then tool versatility is improved, but consistent coolant supply to different cutting arrangements becomes difficult
Solution Approach 1:
The first medium channel in the holder is designed with a universal interface that can supply coolant to the second medium channel in various interchangeable cutting arrangements. This universal connection ensures that regardless of which cutting arrangement is installed, consistent and reliable coolant supply is maintained through the standardized interface between the holder and cutting arrangement.
