SMOOTHING | Polishing  – Stream finishing | Disc finishing

The OTEC mass finishing process produces plateau-like surfaces. These create optimal conditions for rubbing and sliding surfaces due to their high material contact area. The peaks of the surfaces are reduced to Rpk <0.1 µ while the existing grooves are retained. The surface reduces wear and thus increases the service life of highly stressed components such as gearwheels, valves, rocker arms, pistons, expansion screws, camshafts or drive sets. In addition to reducing friction and wear, noise (NVH) is also reduced.
Delivering a perfectly smooth surface with minimal material removal, the OTEC finishing techniques are cost-effective and high-quality processes.

Component properties after processing using OTEC technologies

  • Increased percentage contact area for less friction and wear
  • Reduced roughness values (Ra 0.01 and Rz 0.1 µm)
  • Fewer leaks on sealing faces, e.g. high-speed shafts, sleeve centres
