Diamond Internal-Tooth Ring for Precise Fine Tool Dressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for dressing or cutting teeth of fine machining tools struggle to accurately reproduce the required tooth system geometry on the tools to be dressed or profiled, especially for complex-shaped tooth systems.
Innovation Solution
A tool with an annular configuration and a set of internal teeth made from diamond material, supported by a steel support ring, where the ring element is maximally 5 mm thick and has cutting edges that protrude to freely mesh with the fine machining tool, allowing precise reproduction of the tooth system geometry through controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional tool with incorporated profile is used for dressing or profiling fine machining tools, then the tool structure is simple and easy to manufacture, but it cannot accurately reproduce complex tooth system geometry on the fine machining tool
Solution Approach 1:
The tool is divided into two functionally independent parts: a support ring providing structural support and a separate thin ring element containing the internal teeth. This segmentation allows the thin ring element (maximum 5mm thickness) to accurately reproduce complex tooth geometry while the support ring provides necessary structural strength, resolving the contradiction between manufacturing precision and device complexity.
Solution Approach 2:
The thin ring element with internal teeth acts as an intermediary between the support ring and the fine machining tool being dressed. This intermediary component enables precise tooth system geometry reproduction through controlled movement along the tooth flanks, while the support ring provides the mechanical strength needed for operation.
2Manufacturing precision
If a thin ring element with internal teeth is used to accurately reproduce tooth geometry, then manufacturing precision is improved, but the ring element requires additional support structures for secure operation
Solution Approach 1:
The tool is divided into two functionally independent parts: a support ring providing structural support and a separate thin ring element containing the internal teeth. This segmentation allows the thin ring element (maximum 5mm thickness) to accurately reproduce complex tooth geometry while the support ring provides necessary structural strength, resolving the contradiction between manufacturing precision and device complexity.
3Adaptability or versatility
If the ring element thickness is reduced to maximum 5mm for free movement along tooth flanks, then adaptability for complex tooth systems is improved, but the ring element becomes more fragile and requires support
Solution Approach 1:
The tool is divided into two functionally independent parts: a support ring providing structural support and a separate thin ring element containing the internal teeth. This segmentation allows the thin ring element (maximum 5mm thickness) to accurately reproduce complex tooth geometry while the support ring provides necessary structural strength, resolving the contradiction between manufacturing precision and device complexity.
Solution Approach 2:
The tool combines different materials with complementary properties: the thin ring element is made from diamond material for cutting edges and geometric accuracy, while the support ring is made from steel or similar material for structural strength and rigidity. This composite structure enables the thin ring element to maintain strength despite reduced thickness.

AI summary
The invention relates to a tool for dressing or cutting teeth of fine machining tools, which tool makes it possible to exactly reproduce, in a simple manner, the required tooth system geometry on the fine machining tool which is to be dressed or in which teeth are to be cut. The tool is annular and has a set of internal teeth, the teeth of which mesh, during the tooth-cutting or dressing operation, with the set of external teeth of the fine machining tool in which teeth are to be cut or which is to be dressed. At the same time, the tool has a central longitudinal axis, which extends through the centre point of the opening surrounded by the tool. According to the invention, the set of internal teeth is now formed on a ring element, which is at most 5 mm thick and is produced from a diamond material. The teeth of the set of internal teeth have cutting edges, by means of which said teeth remove material of the fine tool during the tooth-cutting or dressing machining process. The ring element is supported by a support ring, on which at least one support element associated with the support ring opening of the support ring is provided. The ring element is supported on said support element. The teeth of the set of internal teeth formed on the ring element protrude beyond the edge of the support element facing the support ring opening at least over part of the length of the cutting edges of said teeth in the direction of the central longitudinal axis of the tool.
