What is Accelerated Isotropic Finishing?

Leave a Comment

“Isotropic Finishing”, also known in the industry as “accelerated finishing”, This is a mass finishing process of rapidly reducing the surface roughness while providing an isotropic finish to a part.

Isotropic Finishing is commonly performed in traditional vibratory finishing equipment, Roto Finish “Quick Cut” is a liquid accelerant that produces a controlled oxidation and protective layer on a work piece. Ceramic media in the vibratory equipment, removes the oxidized layer of surface highpoints while leaving the low points intact. Roto Finishes “Quick Cut” chemistry processing is reliable achieving refined surface finish measuring rapidly. Surfaces as low as low as 0.5 Ra. are achievable.


Quick Cut II has been successful in various industries including:

  • Automotive               
  • Aerospace   
  • Bearing    
  • Decorative       
  • Hand Tools
  • Medical 

And has provided such benefits as:

  • Superior Aesthetics                                       
  • Larger Radiuses
  • Resistance to Corrosion                                
  • Superior Pre-plate Finishes
  • Longer Part Life                                               
  • Reduction in Part Fatigue

A recent case study by CRW Finishing, put Quick Cut II to the test. A manufacturer of gears requested that the “Ring and Pinion” sets provided have the Ra reduced from as high as 60 Ra to 18 Ra or below and have an isotropic finish. This is turn would reduce the parts metal to metal friction, reducing excessive heat buildup and increasing the part’s overall life.


The total process took less than two and a half hours to achieve the results beyond the client’s expectations. The below chart shows the before and after process, surface readings.

This is only one of many case studies that have definitively proven the success of Rotofinish’s Quick Cut II accelerant. With the proof in the results, CRW Finishing is proud to offer this innovative solution as another tool your success in mass finishing!
