Research and Development are important to us! Our commitment was awarded with the "Innovative through research" seal.


As an international technology leader in mass finishing, OTEC designs and builds systems that reduce friction between components. 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.
