Investing in the best: Speroni’s STP 44 eases graphite machining process for Noida-based HEG Ltd.
Headquartered in Noida (NCR Delhi), India, HEG Ltd. is one of the leading graphite electrode manufacturers in the world. Part of the LNJ Bhilwara group, HEG Ltd. was founded in 1977 with a vision to take India to the world map by becoming a top league player in Graphite Electrode and allied business with commitment to growth, innovation, quality and customer focus.
Today it has one of the largest integrated Graphite Electrode plants in the world, processing sophisticated UHP (Ultra High Power) Electrodes.
The company has come a long way and boasts of exports of around 75% – 80% to more than 25 countries across the globe.
With a mission to become a leading international player in Graphite Electrodes and related businesses, HEG Ltd. is leveraging is its core competencies and thereby investing in the best possible technologies and R&D activities.
The Process
HEG Ltd. undertakes its manufacturing process at their state-of-the-art manufacturing facility at Mandideep, near Bhopal in Madhya Pradesh. With the production capacity of 80,000 MT per annum it has the world’s largest single site plant of Graphite Electrodes.
Machining of graphite ELECTRODES and NIPPLES are challenging, given the brittle nature of graphite. In order to have precise threading cutters setting at the precision of 10 microns level, to save setting time and for tool measurement, HEG invested in Speroni STP 44.
“The process of extrusion is a initial stage of Graphite electrode manufacturing. It goes through various stages like baking, impregnation and graphitization process. After graphitization it is taken for machining,” said Venkatesh Babu, Manager, HEG Ltd.
For machining, HEG is holding world class SPM machines INREMA – a high-end machine imported from Spain is used. “We use Speroni’s STP 44 for cutter setting, without it the cutter tools cannot be set, align with in the required accuracy level of 10 to 15 microns,” added Venkatesh Babu.
The Speroni Advantage
“We manufacture graphite electrodes and nipples diameter from 500 to 750 diameters. By using the Speroni machine we get good quality output i.e electrodes and nipples.
Our products are put into 3D CMM testing also and passes through all the required parameters. This high tech Speroni tools setting machine is so simple and user friendly, initially felt very complicated and time consuming. Professional training provided by Speroni experts, now within two hours each cutter is being set,” said Venkatesh Babu.
