Centrifugal Isotropic Finishing is a high-intensity surface finishing method that uses high centrifugal forces to quickly produce very refined surfaces and isotropic properties. It multiplies the effects of abrasives on part surfaces, allowing edge and surface finishing to be completed in less than one tenth the time of conventional methods. 3D imaging shows the reduction in surface texture irregularities after centrifugal isotropic finishing.

Centrifugal Isotropic Finishing
This is a high-intensity edge
and surface finishing method
that is useful for producing
very refined surface finishes
and functionally useful
isotropic surfaces.
The method makes use of
high G forces generated
centrifugally to multiply the
surface interaction of abrasive
or polishing material with part
surfaces. It is not uncommon
for edge and surface effects to
be developed in cycle times
less than 1/10th of more
conventional methods.
