'An indigenous technology from IIT Madras can now produce new-generation superabrasive tools'

"Grinding industries have aired their voices for developing advanced superabrasive cBN/diamond tools that meet high productivity and energy-efficient material removal requirements and customization based on local needs.

A research team led by Dr. Amitava Ghosh at IIT Madras has used advanced chemical bonding technology with an application-specific novel formulation of filler material and controlled spacing of grits on the tools by an indigenously developed semi-automatic grit-printing device.

The team recommends application-specific-advanced coatings to develop such new-generation superabrasive tools. The novel formulation offers an excellent blend of strength, wear resistance, and wetting characteristics (ability to spread well in a liquid state with low contact angle on solid superabrasives during brazing). The grit-planting (planting/placing of grits in pre-defined co-ordinate position on grinding wheel's working surface) setup allows a manufacturer to print grit in customised pattern to suit the requirement of an application. The recommended coating enhances the durability of the bond, thus adding life to the developed tools."
