History of GMT - Our association with M/S. Techno Valves.

This company manufacture different kinds of non ferrous valves for gas industries. They have a number of ACE CNC Lathes fitted with GMT 2 Jaw Power Chucks. Sometime in Feb 2010 our Mr. Mahendran and Mr. Karthikeyan visited them and met Mr. Rohit Behani, Exec. Mfg. & Sales, Techno Valves and created enquiry for  200 mm dia. Power Operated Power Indexing chuck suitable for ACE CNC Lathe. However, in early July 10 customer decided to order for Mazak CNC Lathe Model Quick Turn Star and asked for fresh quotation for 200 mm dia Power Operated Power Indexing chuck. Mr, Sengupta who retired from LMW as GM and joined Mazak India Kolkatta interacted with GMT. Since he had several interactions with GMT during his tenure at LMW,  he understood the products thoroughly and helped GMT, Techno and Mazak   to initiate discussions and sort out several technical issues viz. dedicated Power Pack for Power Operated Power Indexing chuck, hydraulic and electrical circuit and logic write up ( Interfacing for indexing chuck). The details were sent to Mazak Singapore.  Order for  2B 200 Power Operated Power Indexing chuck complete package including Power Pack and all accessories including special jaws was placed upon us on 17^th Aug. 10.

On receipt of the order further finalization of jaw design took place. We had difficulty in one particular component for offering special jaws. We overcame the difficulty and offered modified jaw design. Received Spindle details and the Chuck with accessories were manufactured. Component trials were done on our LMW Rigi 25 CNC Lathe. The chuck with accessories were dispatched on 20^th Feb. 10.

The Mazak Machine was installed in the new factory of Techno Valves and our team visited on 20^th Apr. 10 to commission the chuck. The chuck successfully commissioned with electrical interface with the Mazak Engineer and our Mr. Kandan. Final trials were taken and obtained report from Techno valves that the chuck is working satisfactorily.

History of GMT - Manual Chucks - India Pistons story

GMT chucks proved very successful in machining auto liners made of CI Castings. India Pistons one of the leading manufacturer of liners had machining problems. PV suggested certain changes in liner casting so that the special jaw to suit our chuck will ensure firm grip on the liner during machining. 

India Pistons were very happy with the chucks performance and recommended our chuck to all their subcontractors and we sold a number of our 3B 250 mm chucks with special jaws....

History of GMT - Manual Chucks - Part-2

Physically chucks were taken for demo to Machine Tool Builders factories, HMT units at Bangalore, Kalamassery and Pinjore. Industrial Plants and Texmaco Ward.

PV personally  visited with Voltas reps to HAL Koraput, MTPF Ambernath BHEL Tiruchy and demonstrated our chuck and gained their acceptance in spite of lower priced scroll chuck. L. Subramaniam of our sales department was entrusted to carry out demos.  Heavy metal removal on castings and forgings using full HP of the machine. An ammeter was used in the electrical circuit to check how much current is drawn during machining. Machines were unable to withstand cutting load. But the Chuck did not loose its gripping force during machining...

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.

History of GMT - Surface and Bed Plates - Part-3

Although our prices were high, we were securing a number of orders from Defence and Public Sector due to the ribbing design of our surface plates. The rigidity of the plate and capability to match and assemble surface plates together also worked in our favour. Notable users:

• Vikram Sarabhai Space Center 
• Nuclear Fuel Complex

We developed Portage Layout Table for precision measurements. Bendix US were making Layout Marking Machine. Bajaj Tempo and Hindustan Motors wanted such Tables. Size of the table 4000 x 2500 mm consists of 8 nos. 1000 x 1250 mm plates matched and assembled. The table top will have precision slots 12 mm width 250 mm pitch distance on length and breadth of the table. Bendix arm will travel on the slot manually. The plate is mounted on speciall. low height CI legs so that the height of the table from floor is max. 500 mm....to be continued
