Cutting Tool Integral Coolant Spacing Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools with coolant supply systems interfere with the clamping mechanism, complicate insert replacement, and do not efficiently deliver coolant close to the cutting edge, leading to increased manufacturing complexity and reduced user friendliness.
Innovation Solution
A cutting tool design with an integral coolant conveying member that is spaced from the locking mechanism and positioned close to the cutting edge, featuring coolant channels that exit near the active cutting area, and utilizing convex pins for secure and precise insert seating, minimizing interference with the clamping system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coolant conveying member with nozzle is used to deliver coolant close to the cutting edge, then coolant delivery efficiency is improved, but the nozzle blocks access to the clamping component and complicates insert replacement
Solution Approach 1:
The cutting tool system is divided into functionally independent components: the coolant conveying member is separated from the clamping mechanism, allowing each to perform its function without interfering with the other. The coolant conveying member can be positioned to deliver coolant effectively while the clamping mechanism remains accessible for insert replacement.
Solution Approach 2:
The coolant conveying member is positioned in a spatial arrangement that resolves the conflict between coolant delivery and clamping access. By adjusting the vertical and horizontal positioning dimensions, the system achieves both effective coolant delivery to the cutting edge and unobstructed access to the clamping component for insert replacement.
2Reliability
If a sturdy coolant conveying member is used to ensure reliable coolant delivery, then coolant supply reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The coolant conveying member is integrated with the tool holder body as a single integral component. This merging of functions reduces the number of separate parts, simplifies manufacturing processes, and eliminates the need for complex assemblies while maintaining sturdy and reliable coolant delivery to the cutting edge.
3Manufacturing precision
If the nozzle is extended over the cutting insert to minimize distance to cutting area, then coolant delivery precision is improved, but interference with clamping component occurs
Solution Approach 1:
The coolant conveying member is designed with localized coolant delivery points positioned precisely where needed at the cutting area. This allows minimal extension over the cutting insert to achieve effective coolant delivery without the need for a long nozzle that would interfere with the clamping mechanism.

AI summary
The present invention relates to a cutting tool comprising a tool holder body (14; 14') having a shank portion (12; 12') and a head portion (13; 13'). The head portion has an insert seat (15; 15'), wherein a cutting insert (20; 20') is detachably mounted by means of a locking member (18; 18'). The seat comprises at least one bottom surface (16; 16') on which the cutting insert rests. A coolant conveying member (29; 29') is integral with the tool holder body. A normal (N; N') to the at least one bottom surface (16; 16') intersects the coolant conveying member, such that the coolant conveying member at least partially covers the cutting insert. The coolant conveying member (29; 29') is spaced from the locking member (18; 18') and the cutting insert (20; 20') when viewed in side view.
