Cutting Insert Clamping Holder for Repeatable Tool Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools require repeated adjustment of the clamping mechanism to change cutting inserts, which limits the ability to maintain a predefined location for the cutting insert during operations.
Innovation Solution
A cutting tool design where the clamping holder is set on the base body once, allowing for separate axial and/or radial position setting and tension fixation of the cutting insert, enabling changes in cutting inserts without re-adjusting the clamping holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cutting insert is clamped directly against the base body via a clamping claw, then the clamping structure is simple, but the cutting insert position cannot be precisely adjusted and maintained when changing inserts
Solution Approach 1:
The clamping structure is divided into separate functional components: a clamping holder that provides positioning and a clamping claw that provides clamping force. This segmentation allows the positioning function to be independent and precise while the clamping function remains simple and removable.
Solution Approach 2:
The clamping holder acts as an intermediary element between the base body and the cutting insert. It provides a stable positioning interface on the base body while allowing the cutting insert to be clamped and removed without affecting the holder's position, thus maintaining positioning precision during insert changes.
2Productivity
If the clamping claw is used to clamp the cutting insert directly against the base body, then the clamping action is direct and simple, but the cutting insert must be re-adjusted every time it is changed
Solution Approach 1:
The clamping holder is pre-positioned and fixed to the base body at the desired location before the cutting insert is installed. This preliminary positioning action eliminates the need for re-adjustment when changing inserts, as the holder already defines the correct position.
Solution Approach 2:
The clamping holder serves as a reusable intermediary that remains in place on the base body while different cutting inserts are clamped to it. This allows rapid insertion and removal of cutting inserts without moving or re-adjusting the positioning element, significantly reducing changeover time.
3Reliability
If the clamping holder is made positionally adjustable and fixed to the base body, then the cutting insert position can be maintained, but the overall structure becomes more complex
Solution Approach 1:
The system is segmented into a position-adjustable clamping holder that is fixed to the base body, and a separate clamping claw that is not permanently attached. This allows the holder to provide stable positioning while the claw remains a simple, removable clamping element, balancing reliability with structural simplicity.

AI summary
The invention relates to a cutting tool having a main body (4) extending along a longitudinal central axis (9) and a cutting insert (1), which is held on the main body (4) in an axially and/or radially positionally-adjustable manner and can be tensioned by means of a clamping claw (3). According to the invention, the cutting insert (1) is held by a clamping holder (2), which is held in a positionally-adjustable manner on the main body (4), and which can be tensioned on the main body (4) by means of the clamping claw (3) pressing against the cutting insert (1).
