Automotive

Optimized surfaces for reduced friction
and improved drivetrain efficiency.

The surface quality of engine and drivetrain components is key to reducing friction and wear. OTEC’s Stream Finishing process optimizes surface topography and microstructure, ensuring ideal run-in conditions and improving efficiency in both combustion engines and electric drives.

Finishing process
benefits

Friction-optimised surfaces and reduced wear by increasing pitting resistance and reducing micropitting.

Mass Finishing Process

  • Uniform surface finishing thanks to complete immersion in rotating media.
  • Simultaneous movement of media and workpiece ensures thorough, all-around processing.
  • Multiple finishing steps—deburring, rounding, and smoothing—in a single cycle.
  • Extremely short processing times, from just 20 seconds.
  • Fully automatable processes with consistent, repeatable results.

Surface Finishing Process

  • Friction-optimized surfaces for improved performance and reduced wear (e.g., electric drivetrain transmissions).
  • In combination with shot peening (smoothing of gears after peening).
  • Increased pitting resistance and reduced micropitting through compressive residual stress introduction.
  • Compatibility with low-viscosity or water-based lubricants.
  • Pre- and post-treatment of wear-resistant layers for extended component life.
