About new superabrasive tools-

• 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.
• In a nutshell, these superabrasive tools can be produced using active brazing technology with remarkably striking attributes of high crystal exposure above bond level. 
• The joint strength and wear-resistant characteristics of bond of these tools are superior to those of their commercial counterparts. 
• These tools can withstand more grinding force, offer significantly higher tool life, and execute load-free grinding of advanced materials with an extremely high material removal rate.
• This indigenous tool is supported by the Core Research Grant (CRG) of the Science and Engineering Research Board (SERB), a statutory body of the Department of Science and Technology (DST).
• The technology can produce new-generation tools with versatile geometries. 
• This technology which fits the requirements of Make-in-India National Mission is under lab validation and is near-ready to be taken up by a start-up or any industry for a full-scale launch.
