1. d)   Finishing :
         Use lower size low abrasive media usually below 10mm (Cylindrical shape) with finishing compounds.
   
   e)   Burnishing :
         Steel Balls are recommended for very good results. For many applications corncob, saw, leather pieces etc. are used. Smaller size low abrasive ceramics can also be used.
   
   While doing Ball Burnishing process make sure that balls are absolutely free from grease, oil & rust. The balls shine like Mirror, to get desired results. If balls are not of proper quality then polishing of the components will not be achieved.
   
   It is recommended to clean/polish balls first.
   
   For Ceramic Media Selection following point should also be considered.
   1)  The selected media should not clogged at any cavity / hole on the job.
   2)  In case part and media are to be separated by screening method then there should be sufficient size difference between size of media & parts for effective separation.
   3)  Size should be capable of doing required operation (deburring or polishing ).
   
   CONCLUSION
   In Vibratory Finishing there are no fixed mathematical formula. Operator must spend some time initially for optimum results. Experience of working with machine will be most valuable asset to get best results from the machine.
