2 WHO WE ARE Estabished in 1973, Micromatic Grinding Technoogies Ltd (MGT ) have been manufacturing a wide range of Externa, Interna, Universa and Specia Purpose Cyindrica Grinders in CNC, PLC and Hydrauic versions. These machines are buit to the exacting requirements of our customers from its 4 pants in Ghaziabad near New Dehi and Bangaore in South India. Production CNC Centeress Grinders, Interna Grinders & Crankshaft Journa Grinders have aso been added to expand the range of new machines being offered from the 4th new pant at Bangaore started in Since 2005, MGT has emerged as the market eader with neary 50% market share in India. Four decades of buiding an organisation Cuture of ethica & transparent working, combined with the pursuit of exceence, drives Team MGT towards its vision of Becoming the Best. We at MGT are constanty seeking new avenues to partner, acquire atest technoogy, skis and quaity-centric processes to cocreate vaue & your success machines deivered wordwide with many repeat references from a Goba customer ist, stand as a testimony to customer s preference for Micromatic Grinding machines.
