History of GMT - Belt Grinders - Part-1

In the early 60s we were manufacturing  Major Back Stand Assembly (MBSA) and Minor Back Stand Idler ( MBSI). These were manufactured for M/S. Carborundum Universal as per their drawings. Carborundum were buying the assembly from us and then fixing on a Base and Motor and selling as a BeltGrinder.

Carborundum Universal's Marketing Chief hit upon a idea of selling Belt Grinders using MBSI mounted on a base with motor and a belt between motor pulley and MBSI idler pulley as a demo unit.The entire assembly is so designed so that it could be accommodated inside the boot of then Standard Herald Car.  Carborundum's  Marketing staff would drive the car to the customers works to demonstrate. Carborundum sold coated abrasive belts, so both belts and grinders were sold for a while very successfully for a while.This project  was abandoned due to some reasons.

 GMT Belt Grinders

GMT then started developing Heavy Duty Double Ended Belt Grinders using 3500 x 75 mm width Belt for TELCO Jamshedpur for removing flash of die forged components. Removal of forging flash was a challenge. Abrasive Belt Grinding was the only solution for this. TELCO  Jamshedpur had German  Heavy Duty Belt Grinders in their forge shop and wanted GMT to develop such Grinders. We took the design and supplied 2 such machines.

GMT history - 1980-1990

GMT was focusing on PS model Power Chucks and 300, 400, 600 and 900 mm Lapping Machines. In the 80s and 90s GMT again built SPM and Special Power Chucks and Hydraulic Cylinders for Escorts Patiala. 1500 mm Lapping Machine was manufactured for BHEL Bhopal for lapping White Metal Bearing Pad used in Water Turbine. GMT received order from BHEL although M/S Lawrence UK was a strong contender for the order for Lapping Machine. They supplied a machine to Mitchell Bearings one of the leading manufacturer of white metal bearing in UK. Engineers in BHEL had faith in Lapping Technology of GMT and the order came to us for the machine.

High Speed Hollow chucks, Hollow High Speed Cylinders were also developed during 80s. Belt Grinders i.e.  Single, Double Ended and Platen Grinders were also developed in the 80s. Platen Grinders were developed for MICO, Bangalore with dust extraction system.
