Dressing Tool Recesses for Uniform Grain Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dressing tools fail to achieve a perfectly uniform distribution of hard material grains on their working surfaces, affecting the quality of the grinding effect.
Innovation Solution
The tool features indentations on its base body, adapted to the geometry of the hard material grains, allowing for precise positioning and a defined distribution density, with the indentations being drilled, embossed, or laser-etched, and filled with conductive adhesive to ensure the grains remain securely embedded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If adhesive coating method is used to apply hard particles, then rapid coating is achieved, but uniform distribution density of hard particles cannot be ensured
Solution Approach 1:
The patent creates recesses in the base body before applying the adhesive coating. These pre-formed recesses serve as predetermined positions where hard particles will be retained, ensuring uniform distribution density across the working surface while maintaining the efficiency of the adhesive coating method.
Solution Approach 2:
The patent applies adhesive selectively in the recesses rather than as a uniform coating across the entire surface. This localized application of adhesive ensures that hard particles are held only at specific predetermined positions, achieving uniform distribution while maintaining rapid coating capability.
2Ease of manufacture
If conventional adhesive coating method is used, then simple manufacturing process is maintained, but grain distribution quality deteriorates
Solution Approach 1:
The recesses are created in the base body before the adhesive coating step, establishing predetermined positions for hard particles in advance. This preliminary structuring enables precise grain distribution while keeping the overall manufacturing process simple and suitable for industrial production.
3Productivity
If hard particles are applied without recesses, then rapid coating is achieved, but particle retention and orientation control are insufficient
Solution Approach 1:
Recesses are pre-formed in the base body to create retention structures before particle application. These recesses mechanically hold the hard particles and control their orientation, ensuring reliable particle retention while maintaining the efficiency of rapid adhesive coating methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method ensures a uniform and optimized distribution of hard material grains, enhancing the cutting effect and service life of the tool by allowing for precise grain placement and retention, particularly with a nickel plating process that encloses the grains.
Implementation Method 1
The recesses formed in the base body are filled with a preferably electrically conductive adhesive
Implementation Method 2
The invention also provides that the resulting particle coating is subsequently electroplated with nickel, whereby the nickel layer is deposited on the adhesive and the hard particles are encapsulated by the nickel bond
Implementation Method 3
According to the invention, the recesses in the base body are created by drilling or stamping

AI summary
The invention relates to a dressing tool with a base body (2) whose working surface (6) is covered with hard aggregate grains (7) distributed across the base body (2). According to the invention, recesses (8) for receiving the hard aggregate grains (7) are formed in the base body (2). These recesses are then filled with an adhesive, the excess adhesive is removed from the base body (2), and the hard aggregate grains (7) are then flung onto the base body (2), so that only the grains (7) located in the recesses (8) remain adhered to the working surface of the tool. These hard aggregate grains can then be bonded to the base body by a physical and/or chemical bond. This ensures a precisely definable distribution of the grains across the working surface of the tool.
