NGPG – 8 Year journey for end to end Innovation



A group of executives of machine tool manufacturing companies and precision components manufacturers met in July 2008 at Ghaziabad, a small town in the outskirts of Delhi. This meeting was organized by Mr. N.K. Dhand, CEO, Micromatic Grinding Technology, a leading machine tool manufacturer in India. Their discussion centered on Precision Manufacturing in India. This was an early initiative very much in line with the now famous Make in India movement spear headed by the current Prime Minister of India, Mr. Narendra Modi. This journey started in 2008 has resulted in a commercially viable indigenous machine tool, capable of manufacturing higher precision engineered components in India. This machine (NGPG) was inaugurated on June 24th 2016 at IIT – Madras, India.


This report is a brief summary of the 8 – Year journey of collaborative development, leading to end to end innovation (i.e.) from concept to commercially viable end product.

Following are a few pictures from the kick off meeting held at Ghaziabad on July 1, 2008. The meeting was attended by CEOs of several precision machine tool manufacturers, Senior Managers from Precision components manufacturers, Senior advisers from Indian Machine Tool Manufacturers Association (IMTMA).


Kick off meeting held at MGT at Gazhiabad, Delhi July 1, 20008

 Dr. K. (Subbu) Subramanian, President, STIMS Institute (then working at Saint-Gobain Co.)  was invited to this meeting to offer his views on manufacturing and innovation. He offered an outline for a road map for machine tool developments in India. He suggested the following outline:

  • Step 1: Target Industries, applications and their market opportunity (Driven by National and Global Policies): Inside of India; in Selected Geographies?
  • Step 2: There are similar applications (e.g): Cylindrical Grinding, everywhere. What is the “Served Market” for the IMTMA members?
  • Step 3: What industries and markets that IMTMA members want to drive? Proactive Vs. Reactive ?
  • Step 4: There is a natural evolution path for Core Capabilities  depending on the           component/supplier capabilities.
  • Step 5: Leverage capabilities of Individual members or industry suppliers?  (e.g): Grinding Technology
  • Step 6: Leverage capabilities of a collection of members and their capabilities for  “Integrated Solutions”? Technology Value Chain?

Dr. Subramanian also explained the need for an eco-system for collaborative development in India, as an unique alternative to the industry – university models noted in developed nations such as USA and Germany.


At the end of this meeting the following conclusion was reached:

Indian Machine Tool manufacturers and their customers for the machines made in India cannot achieve tolerances for less than 1 micron (roundness, taper, size holding, …) with out in-process gaging. But in-process gaging cannot be used for many precision components including non-round grinding applications such as cam lobe grinding or match grinding of precision parts. Such machines can be imported but technologies to manufacture such machines are not available for sale that can be purchased from the overseas manufacturers. Lack of such higher precision machine tools also impacts further progress inside of India in the use of advanced grinding solutions – such as high speed CBN grinding – in the manufacturing sector.

After such clearly outlined industry need, Dr. Subramanian and Mr. N.K. Dhand contacted Prof. Babu at IIT – Madras. Further discussions together with Mr. Mohanram, Scientific Adviser, IMTMA resulted in a research proposal, which was timely for submission to a RFP for research in the year 2010, supported through the Office of the Principal Scientific Advisor, GOI. The proposal was accepted by GOI. The review process that followed was valuable as noted in the following exchange:

Reviewer Comment: The proposal should make the technical details of what is meant by the next generation precision grinding machine. This information given in the proposal is too general and is not sufficient to judge the quality of the proposal. It is also not proper to identify an existing machine tool of the sponsor without establishing its superiority over the existing machine tools of the other brands.

I recommend that the first phase of the project should compare and identify the  best grinding machine presently available and then spell out the requirements of the next generation precision Grinding machine so as to take up the second phase project involving the development.

Response:   There will be a parallel effort to calibrate cylindrical grinding machines available in India and the state of the art of such machines available worldwide. With this data set of the cylindrical grinding machine capabilities inside of India and those available abroad should be the reference for developing the next generation precision grinder. The framework developed in the project will provide the necessary guidance for building the next generation precision grinders.

After further reflection, the following factors were also identified by the R&D team:

  • In most industries the commercial developments are incremental. But the history of such development is not a well-documented continuum. Hence while many companies can manufacture higher precision machine tools, they cannot “teach” a comprehensive methodology for someone else to follow!
  • Often the legacy knowledge is also lost with the retirement or departure of experienced and senior level workers as each generation of machine tool is developed or due to changes in company business conditions and strategy.
  • The research pursued by individual academic researchers often delve into depth of one or the other aspect of precision machine tools such as stiffness, dynamic stability, etc. Rare few if any study all aspects of machine tool developments needed for the development of a higher precision machine tool. This requires an integrated or System View of the research and development.
  • Hence the System Approach developed and advocated by STIMS Institute and the related Transformational Skills were adapted as the frame work for the development of the Next Generation Precision Grinder (NGPG).

The NGPG project was approved by the end of 2012. It has progressed well to achieve all the goals set forth in the visionary meeting held at Ghaziabad in 2008. The machine was inaugurated on June 24th 2016 at IIT – Madras by Dr. R. Chidambaram, Principal Scientific Advisor, GOI. The project, its progress and the end result – a commercially viable next generation machine tool developed as an outcome of GOI funded research carried out through active team of collaborators from Industry, Academia, Govt. Research labs. and world experts – is a true testament to the application of System Thinking and Transformational Skills and their impact. We are pleased to document below the progress and the results through the following slides:

Slide12 As it is often said “Success Breeds Success”. The success of the NGPG project and the collaborative environment created across the industry / university research and manufacturing community has resulted in the development and formation of the Advanced Manufacturing Technology Development Center (AMTDC). This is a collaborative effort across six machine tool / components manufacturers, IIT – M supported by GOI R&D funding.  STIMS Institute will continue its role of mentoring and guidance for the success of this consortium and its impact on the manufacturing sector.
