IN POLE-POSITION - OTEC CONFINES FRICTION TO THE RACETRACK

While engineers in the automotive industry are always looking for ways to optimise efficiency, smooth running and emission management, the focus in motorsport is on pushing performance to its limits. As an international technology leader in mass finishing, OTEC designs and builds systems that reduce friction between components, benefiting both the premium car segment and motorsport. The heat, stresses and material abrasion caused by friction are detrimental to the precision and service life of all components. Lower friction means less wear, smoother power delivery and better energy consumption. The aim is always to minimise the influence of friction on the system as far as possible. Component properties of camshafts, gear wheels, valves, shift drum, worm shaft and gear parts can be improved by deburring, rounding, smoothing and polishing with OTEC finishing process.

Precision Finishing for Peak performance in Motor sport

Surface processing on the individual components of racing cars plays a central role for performance in autosports. The process not only achieves perfectly polished surfaces, but also improves the components’ appearance. Tests show a significant performance increase of 5% after OTEC processing. OTEC machinery can process typical motorsport components such as clutch shafts, camshafts, drive shafts, racks, pinions, pistons, shifting dogs and brake disc chambers.
