Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Milling tools require multiple sizes for different groove applications, leading to high costs and storage needs, while existing tools lack adjustable milling widths without compromising strength, stability, and precision.
Innovation Solution
A milling tool holder with two adjustable parts that can be locked into various positions along a longitudinal axis, using a spacer element and locking mechanism for precise torque transmission and adjustable milling width, ensuring high stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple slot and parting cutters of varying sizes are used to produce multiple slots of different sizes, then different milling widths can be achieved, but costs increase and storage requirements increase
Solution Approach 1:
The milling tool holder is designed with a modular structure comprising a first holder part and a second holder part that can be variably positioned relative to each other. This allows a single tool holder to perform multiple functions by adjusting the position of the second holder part, thereby achieving different milling widths without requiring multiple separate tools. The cutting inserts on both holder parts work together to create variable slot widths, making one tool replace multiple specialized tools.
Solution Approach 2:
The milling tool holder is divided into separate modular components: a first holder part with first and second cutting inserts, and a second holder part with third and fourth cutting inserts. These segmented parts can be independently positioned and adjusted along the longitudinal axis, allowing flexible configuration of the milling width. This segmentation enables the system to adapt to different machining requirements while maintaining a compact, adjustable structure.
2Adaptability or versatility
If a milling tool is designed with adjustable milling width, then versatility improves, but structural complexity increases
Solution Approach 1:
The second holder part is designed to be nested within or alongside the first holder part, with both parts sharing a common longitudinal axis. The holder parts contain each other in a compact arrangement, reducing overall structural complexity while enabling variable positioning. This nesting approach allows the adjustable mechanism to be integrated into a compact form factor without requiring complex external adjustment mechanisms.
3Adaptability or versatility
If the holder parts are variably positioned to adjust milling width, then adaptability improves, but maintaining strength and stability becomes more difficult
Solution Approach 1:
The milling tool holder employs a dynamic adjustment mechanism that allows the second holder part to be variably positioned along the longitudinal axis relative to the first holder part. This dynamic positioning capability enables continuous or discrete adjustment of the milling width while maintaining structural integrity. The holder parts can be locked at different positions to provide both adjustability and stability during operation.
4Adaptability or versatility
If the holder parts are variably positioned to adjust milling width, then adaptability improves, but maintaining precision becomes more difficult
Solution Approach 1:
The adjustment mechanism for positioning the second holder part relative to the first holder part employs precision mechanical elements such as threaded fasteners, keyed connections, or indexed positioning systems. These mechanical substitution approaches replace less precise adjustment methods and provide repeatable, accurate positioning at different milling width settings. The locking mechanism ensures that once positioned, the holder parts maintain their relative positions with high precision during the milling operation.

AI summary
The invention relates to a milling tool holder (10), comprising: a first holder part (16) having a first cutting-insert receptacle (13a) for receiving a first cutting insert (12a) and having a second cutting-insert receptacle (13b) for receiving a second cutting insert (12b); a second holder part (18), which can be variably positioned along a longitudinal axis (32) relative to the first holder part (16) in order to set a milling width, the second holder part (18) having a third cutting-insert receptacle (13c) for receiving a third cutting insert (12c) and having a fourth cutting-insert receptacle (13d) for receiving a fourth cutting insert (12d); a locking element (20) for fixing the first and second holder parts (16, 18) at the set milling width. In the assembled state, the first and second holder parts (16, 18) are positioned relative to each other in such a way that the third cutting-insert receptacle (13c) is arranged between the first cutting-insert receptacle (13a) and the second cutting-insert receptacle (13b) in the circumferential direction (34) and that the second cutting-insert receptacle (13b) is arranged between the third cutting-insert receptacle (13c) and the fourth cutting-insert receptacle (13d) in the circumferential direction (34).
