Problem Statement
- Inefficient Filler Alloy Use: Current methods waste filler alloy, which is costly.
- Diamond particles do not bond well in some filler alloy areas, leading to material inefficiency.
- Existing techniques result in uneven diamond grit distribution, affecting tool performance.
- Grit Accumulation: Imprecise placement causes grits to cluster in spots, reducing tool uniformity.
- Current methods struggle with Lack in the precise positioning of Small abrasive Particles.
- Template Dependency: Some techniques rely on templates, limiting flexibility in grit patterns.
- Adhesive Weakness: Using adhesive can weaken joint strength, risking tool durability.
- Wasted Filler Alloy: Some processes waste filler alloy, inefficiency in material use.
- Controlled Grit Protrusion Challenge: Achieving consistent grit height is difficult.
Hence, there is a need for Flexible Grit Arrangement, which is disclosed in the present patent allowing versatile grit placement without template/adhesive.
Technology
- The present patent discloses a novel Method of Developing Diamond Dresser Tools having Grits in Patterned Array. This method is used for precise patterned dresser tool creation. It uses a T-shaped design with micro-holes, synthetic diamond grits, placed using vacuum-operated technology, dipped in a specialized alloy, & positioned accurately. Consistent grit height is ensured through force measurement, offering customization & versatility.
