Automotive Shock Absorbers
Challenge: Tenneco is one of the world’s leading manufacturers of ride control products for the automotive original equipment and aftermarket. Tenneco is constantly searching for new ways to better serve their customers and to deliver consistent high quality at a fair price. One of those challenges came from a leading manufacturer of high end sport/luxury vehicles. This new product demanded an unusually high level of accuracy not seen before in OEM products. Tenneco has used Haven Manufacturing’s equipment since the late 1970s with consistent and excellent results, so the decision to solicit Haven’s advice on this new project was an obvious one. The application called for a single end finishing machine, machining an I.D. and O.D. chamfer, end face, and I.D. or O.D. reduction, all in one cycle. This seemingly straight forward task was anything but ordinary, given the extremely tight tolerance and repeatability requirements.
