Hardness tester helps buses survive
India
When Ashok Leyland came to replace its existing Zwick hardness testing equipment it needed to add greater flexibility as well as reducing the measurement uncertainty and test time.
From its humble beginnings in the late 1940s in Chennai, formerly Madras, and as part of the British Leyland organisation, Ashok Leyland began a journey which has led to global success in the transport solutions industry Eight out of ten metro state transport buses in India are from Ashok Leyland, and at 70 million passengers a day, Ashok Leyland buses carry more people than the entire Indian rail network

New approach to torsion testing
Torsionline is a new generation of testing machines to study the torsional influence on materials and components.
In addition, it needed to issue traceable certificates of calibration and conformity.
The main challenge was the additional requirement to test a wide range of case hardened, sectioned components of many different sizes on one hardness tester.
Although the load requirement using Vickers scales from 25gf to 2kgf was not a problem, the wide range of specimen sizes meant that that the standard Vickers hardness machine was just too small for the application.
After visits to the customer and detailed discussions regarding the application Indentec, Zwick's specialist hardness testing division, was able to find a unique and perfect solution.
The company developed an extended version tester with 250mm vertical daylight, 150mm throat depth, and additional tooling to support the components.
Ashok Leyland is now able to ensure that its measurement parameters meet international standards, and are traceable to the National Physical Laboratory in the UK, through Indentec's ISO17025 UKAS approved hardness laboratory.
The easy-to-use and automatic system enables it to check both its own production, and the quality of incoming materials from suppliers, which will definitely lead to an increase in the quality of the final product.
Zwick is pleased to have been a supplier to Ashok Leyland in a relationship, which has spanned many years and has benefited both organisations.
Since the establishment of a joint venture agreement in 2004, Zwick has firmly established its own presence in India.
Offering a unique product range combined with an excellent package of localised support in major cities, Zwick is already achieving its goal of getting much closer to its Indian customers. Request a free brochure from Zwick Testing Machines ...
