Technology developed at IIT Madras can produce new-generation superabrasives tools

Dr. Amitava Ghosh’s research team at IIT Madras used advanced chemical bonding technology with an application-specific novel formulation of filler material. The technology that meets the requirements of the Make-in-India National Mission is being tested in laboratories and is nearing completion.

  • New technology has the potential to create next-generation multi-point/single-layer superabrasive tools.
    Grinding industries have spoken out in support of advanced superabrasive cBN/diamond tools that meet high productivity and energy-efficient material removal requirements.

New technology produces multi-point/single-layered superabrasive tools that can be used for extremely high productivity and energy-efficiency grinding of advanced materials. These tools also have an extended tool life. The products produced to provide high performance and high tool life and reduce tool cost dramatically.

The grinding industry has voiced its desire to develop new-generation superabrasives, including cBN/diamond grits that meet high productivity and energy-saving requirements for material removal and customization to meet each customer’s specific requirements.

Using advanced bonding technology, a team from IIT Madras produced high-precision grit tools using an indigenous system that allows a manufacturer to control the spacing of grit grains on the grinding wheel to deliver the required grinding results.

Researchers at IIT Madras have developed a novel formulation that offers very good strength and resistance for developing a new generation of superabrasives tools. Novel formulations can offer high strength, wear resistance, and wetting characteristics (the ability to spread well in a low-contact state on solid superabrasives when used for brazing). This enables manufacturers to print grit in a pattern perfectly matched to the application and produce highly productive tools. This improves the hardness of the bond, extending the tool’s life.

These tools are made using an advanced technology that allows the bonding of superabrasives to be activated, thereby providing a high degree of crystal adsorption and thus allowing rapid removal of all types of materials. They are stronger and more durable than their industrial counterparts and provide a higher removal rate and tool life than their industrial counterparts. These new tools can withstand greater force when grinding, offer a longer tool life, and execute load-less grinding of advanced materials with a high removal rate.

This tool has been developed under a grant from the SERB, a governmental body of government concerned with science and technology. It is cost-effective and offers superior quality.

A new technology is being developed that enables us to produce tools with different geometries. They have developed several tools that are being used to simulate manufacturing processes. This novel way of manufacturing superabrasives has been published recently in the Journal of Manufacturing Process, and patents are under review for approval.

This technology is in development that fits with the Make-in-India goals. It is nearing being commercialized by start-ups or any industry for a large-scale launch. This application-oriented technology of forming fillers on metal substrates using state-of-the-art active-brazing technology is a critical novelty that large-scale manufacturing industries may exploit.
