Delphi-TVS relies on Kennametal Extrude Hone for surface finishing

Manufacturers and quality professionals in industries such as automotive, aerospace, energy, medical, and others requiring high-precision components know that removing particles left at intersected holes and ensuring no micro contamination is a big challenge that cannot be overlooked. Customised complex valves, gears, pinions, and thousands of components can be machined in seconds but can take minutes to get finished completely. This in turn results into production bottlenecks, increased costs, and longer time to market.Delphi-TVS, a joint venture between Delphi Corp., USA and T V Sundaram Iyengar & Sons, India, is one of the largest automotive systems manufacturers in India. It found that its high component volumes approaching a million a year have made hand-deburring unaffordable and then high-precision nature of diesel fuel injectors made TEM solution a necessity. After much investigation, the company chose Kennametal Extrude Hone’s TEM (thermal energy method) solution.
 “We manufacture diesel fuel injection parts – high-volume components. The main issue is burr removal on cross-sectional holes from previous machining operations,” says T N Umasankar, Head – Manufacturing Engineering Department, Delphi-TVS.
Kennametal Extrude Hone is one of the leaders in the field when it comes to providing precision surface solutions for components. Its proprietary technologies such as TEM are solving increasingly complex finishing challenges faced by manufacturers around the world.

“There have been hundreds of installations and continued refinement of our TEM equipment and process,” says Bruno Boutantin, Global Marketing Manager, Kennametal Extrude Hone. “TEM is a rapid, low-cost, high-production process that can process a million or more parts per year by a single machine.”
“The TEM process is particularly appropriate for high-volume applications where conventional deburring departments struggle to keep pace,” Mr Umasankar adds. “It instantaneously cleans up a large number of intersecting holes, threads and hard-to-reach areas in a flash, literally in 20 milliseconds. Its ability to fire multiple components at the same time increases its capacity and cost-effectiveness enormously. Any other process, including high-pressure water jet, will not provide this value.”
Combining vast experience gathered over more than five decades with worldwide application know-how, Kennametal offers proven solutions to many companies working in most demanding environments. In India, Kennametal Extrude Hone is an integral part of Kennametal India Ltd. situated in Bangalore, where its technical centre is well-equipped to support the customer needs.
