Delphi-TVS relies on Kennametal Extrude Hone for surface finishing

July 22, 2014 4:11 pm

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.
