An apparatus for nanofinishing of races of aircraft's blade bearings.

Key Features: 

  • A magnetic abrasive finishing (MAF) apparatus is developed for nanofinishing of races of aircraft's blade bearing.
  • A low cost and more efficient finishing processes used for finishing of blade bearings that reduces friction.
  • Use of a flexible MAF brush which is self deformable.
  • Use of diamond particles in MAF medium to reduce total finishing time.


  • Finishing of races of aircraft's blade bearing. However, it can be also used for other components having similar shape as of blade bearing.
  • Components which are finished by this process do not require any post finishing operations.
  • The developed technology does not destroy the form geometry of the component to be finished.
