Machining Tool Lamella Holder Hooked Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools with lamellas for fine machining surfaces face issues with robustness and complexity in manufacturing and lamella exchange, due to the design of continuous open grooves which weaken the working medium carrier and require diligent mounting.
Innovation Solution
The implementation of complementary hooking members on the lamella holders and the working medium carrier, allowing for a hooked connection that enhances tool stiffness and eliminates the need for open grooves, enabling a more robust and simpler design for manufacturing and lamella exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If continuous open grooves are used to hold lamellas, then lamella exchange is enabled, but the working medium carrier is weakened and robustness is reduced
Solution Approach 1:
The continuous open groove is divided into discreteĉ§½ elements, each with its own cover. This segmentation allows the groove structure to provide lamella retention while maintaining the overall structural integrity of the working medium carrier, as the covers close off the individual slots without requiring the entire carrier to be open.
Solution Approach 2:
Covers are introduced as intermediary elements to close off the open grooves. These covers enable the grooves to function for lamella insertion and retention while preventing the carrier from being structurally weakened by continuous open slots, thus mediating between the need for lamella exchange and structural robustness.
2Ease of manufacture
If continuous open grooves are used for lamella insertion, then lamella exchange is simplified, but manufacturing complexity and diligence requirements increase
Solution Approach 1:
The groove system is segmented into discrete units with individual covers, allowing standardized manufacturing of modular components. This segmentation simplifies the exchange process as each slot can be independently accessed and filled, while reducing mounting diligence through the self-contained nature of each covered slot.
Solution Approach 2:
The covers function as simple, inexpensive components that facilitate easy lamella insertion and removal. These covers require minimal precision in installation compared to continuous groove systems, reducing the diligence required during mounting while enabling simplified lamella exchange.
3Adaptability or versatility
If open grooves are provided in the working medium carrier, then lamella attachment is enabled, but material usage increases and robustness decreases
Solution Approach 1:
The carrier structure is segmented into discrete groove units with covers, allowing material to be concentrated in specific functional areas rather than creating large continuous open structures. This segmentation enables lamella attachment capability while minimizing the overall material removed from the carrier body.
Solution Approach 2:
Covers serve as intermediary elements that allow the grooves to provide lamella attachment functionality without requiring the carrier material to be permanently removed or thinned in continuous open slots. The covers enable attachment capability while preserving the carrier's material integrity.

AI summary
A tool for fine machining surfaces has a working medium carrier with a top face and a bottom face, wherein the bottom face is an attachment side. A set of individual exchangeable strip-shaped lamella holders are provided that each have one or more lamellas in individual or bundled arrangement. The lamellas each are oriented away from the attachment side of the working medium carrier and form in a downward direction remote from the attachment side a common working plane. The lamella holders on a side facing the attachment side are provided with first hooking members and the attachment side of working medium carrier is provided with second hooking members complementary to the first hooking members. The first and second hooking members are joined to each other in a direction perpendicular to the attachment side.
