Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The position of the coolant exit opening in existing turning tools is limited by the design and dimensions of the clamp, restricting versatility and efficiency in coolant distribution.
Innovation Solution
A turning tool design with a separate nozzle unit positioned in a through hole, allowing for versatile placement and orientation, and a removably received nozzle unit that can be easily replaced or adapted for different cutting operations, featuring a coolant passage system with a sealing member for efficient coolant delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the nozzle unit is integrated into the clamping mechanism, then the structure is more compact, but the position of the coolant exit opening is limited by the design and dimensions of the clamp
Solution Approach 1:
The nozzle unit is separated from the clamping mechanism and positioned independently in a through hole on the tool body. This segmentation allows the nozzle unit to be located at optimal positions for coolant distribution without being constrained by the clamp's design, thereby resolving the contradiction between structural integration and coolant distribution flexibility.
Solution Approach 2:
The through hole in the tool body serves as an intermediary structure that accommodates the nozzle unit separately from the clamping mechanism. This intermediary arrangement enables independent positioning of the nozzle unit while maintaining structural coherence, allowing versatile coolant distribution without compromising structural integrity.
2Ease of manufacture
If the nozzle unit is fixed in position, then the manufacturing is simpler, but the adaptability for different turning applications and cutting inserts is reduced
Solution Approach 1:
The nozzle unit is made replaceable rather than fixed, allowing it to be dynamically adjusted or replaced based on specific turning applications and cutting insert requirements. This dynamic configuration enables the system to adapt to different operational needs while maintaining a relatively simple through-hole mounting structure for ease of manufacture.
Solution Approach 2:
The through hole design provides a universal mounting interface that can accommodate different nozzle unit configurations for various turning applications. This universal structure allows the same basic tool body to be adapted for multiple applications by simply changing the nozzle unit, thereby achieving versatility without complicating the overall manufacturing process.
3Productivity
If the nozzle unit is positioned close to the cutting insert, then the coolant delivery is more direct, but the nozzle unit is more exposed to wear from chips and heat
Solution Approach 1:
The nozzle unit is positioned at an optimized location in the through hole that balances coolant delivery efficiency with protection from wear. The separate positioning allows the nozzle to direct coolant effectively toward the cutting insert while being sufficiently remote from the high-wear chip and heat zones, thereby achieving both productivity and reliability.
4Adaptability or versatility
If the nozzle unit is removably received in the through hole, then the adaptability and ease of replacement are improved, but the device complexity increases
Solution Approach 1:
The nozzle unit is extracted from the traditional integrated mounting approach and placed in a simple through hole that allows easy removal and replacement. This extraction simplifies the mounting mechanism to essentially just the through hole itself, reducing device complexity while maintaining high adaptability and ease of replacement.

AI summary
The turning tool comprises a tool body (110; 110, 120) having an insert seat (105) positioned at a front (FE) end of a top surface (114), a clamping mechanism (135), a nozzle unit (151) for directing a coolant fluid towards a cutting insert (130) mounted is the insert seat (105) and a through hole (156) which extends from the top surface (114) to a bottom surface (113). The nozzle unit (151) - separate from the clamping mechanism (135) - is removably received in the through hole (156) and can protrude from the top surface (114).
