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.


  • 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.
