Problem Statement
- In Manufacturing high-quality uni-layer brazed grinding wheels with a predefined array of cBN/Diamond abrasive grits, several challenges are been faced.
- Traditional methods have limitations, including grit clustering, uneven protrusion from the bond level, and the use of templates.
- To address these issues and to improve the precision, control, and efficiency of grit placement, a new system and the method are needed.
- The solution offered by the instant Patent is a pick-drop-place (PDP) technique and system, designed to provide improved control, uniform protrusion, & customizable grit patterns without relying on predefined templates.
Technology
