Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining tools face challenges in quickly and accurately setting and resetting guide rails due to time-consuming processes and inaccuracies, especially when guide rails wear out, leading to tool downtime and reduced efficiency.
Innovation Solution
A machining tool design featuring a guide rail carrier connected via a material joint to a fixed section of the tool, allowing for precise radial and tilting adjustments using a setting means with differential threaded screws, enabling quick and accurate positioning and recalibration of guide rails without releasing fastening means, thus minimizing contamination and deformation under extreme conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide rails are soldered to the carrier body or fastened with screws, then the guide rail is firmly fixed to the tool, but changing or readjusting the guide rail becomes difficult and time-consuming
Solution Approach 1:
The tool is divided into modular components: a carrier body, a guide rail carrier, and guide rails that can be independently replaced. The guide rail carrier acts as an intermediate module that can be quickly exchanged without affecting the entire tool structure, enabling rapid guide rail replacement while maintaining stable fixation during operation.
Solution Approach 2:
The system transitions from a static, permanently fixed guide rail arrangement to a dynamic, adjustable configuration. The guide rail carrier can be quickly detached and reattached, allowing the guide rail position and configuration to be changed based on operational requirements, thus combining firm fixation during use with easy replaceability when needed.
2Manufacturing precision
If guide rails are set radially using conventional means, then the guide rail position can be adjusted, but the setting process is time-consuming and lacks precision in the micrometer range
Solution Approach 1:
Conventional manual setting mechanisms are replaced with a differential threaded screw system that provides precise micrometer-level adjustment. The differential threading mechanism translates small rotational movements into extremely fine linear displacements, enabling accurate radial and tilting adjustment of the guide rail carrier without time-consuming manual operations.
Solution Approach 2:
The setting mechanism utilizes differential thread pitch to achieve precise control over the guide rail carrier position. By changing the thread parameters (different pitch values on adjacent threads), the system achieves high-resolution adjustment in the micrometer range, transforming coarse mechanical movement into fine positional control.
3Reliability
If the guide rail is firmly fixed to ensure stability, then positioning accuracy is maintained, but fine-setting and recalibration become inaccurate due to stable fastening
Solution Approach 1:
The system employs a dynamic fixation mechanism where the guide rail carrier can be easily detached for setting operations and then firmly secured during operation. The quick-release fastening system allows the carrier to be removed, positioned with micrometer accuracy using differential screws, and then locked in place, achieving both fine-setting capability and operational stability.
Solution Approach 2:
The fixation system is segmented into a removable guide rail carrier and the main tool body. This separation allows the carrier to be independently adjusted and recalibrated without affecting the overall tool stability. Once set, the carrier provides stable fixation during operation, while its modular nature enables precise recalibration when needed.
4Manufacturing precision
If guide rails are adjusted frequently to maintain optimal position, then manufacturing accuracy is improved, but tool downtime increases due to repeated setting operations
Solution Approach 1:
The guide rail system is segmented into a quickly exchangeable carrier module. When adjustment or replacement is needed, only the carrier needs to be removed and replaced, not the entire tool. This modular approach minimizes tool downtime while allowing frequent optimization of guide rail position to maintain bore straightness and manufacturing accuracy.
Solution Approach 2:
The guide rail carrier can be pre-set and calibrated outside the tool during maintenance periods. Multiple carriers with different pre-configured settings can be prepared in advance, allowing quick swapping during operation to adapt to different machining requirements without time-consuming on-site adjustments.

AI summary
A machining tool for producing or machining bores, respectively, with high positional and/or surface quality, comprising a tool axis and a tool carrier section, which carries at least one tool blade and at least one guide rail, which radially supports the tool carrier section on a bore wall. The guide rail can be set with respect to its radial position and with respect to its tilt relative to the tool axis by means of a setting means, which engages with a guide rail carrier. In order to put together a tool, which operates highly precisely and with little effort, the guide rail carrier is connected via a material joint to a section that is fixed to the tool, thus either to the tool carrier section or a component, which can be firmly connected thereto, and the material joint can be blocked by means of the setting means.
