Maintaining the right ratio of media to work pieces is essential to achieving precise, repeatable results in mass finishing processes where work pieces and media loosely tumble in the processing bowl.
Ensuring that the work pieces are properly embedded in the media allows the media to perform its designated grinding or polishing function as well as cushioning the work pieces from damage caused by part-on-part impingement.
Building upon our last post on the series about navigating the complex media selection considerations, Rosler’s team of experts now discusses tips for determining the best media-to-work piece ratio.
