Tumbling Media

The advantage of tumbling media is the inclusion of a bonding agent that continuously recedes and exposes more abrasive particles. In result, they maintain a relatively consistent removal rate over at least have the size of its shape.

Your desired surface finish determines the needed characteristics of your chosen media, such as size, shape, internal particle size, and mineral composition. Often times, a project requires a trial process before the development of a mass finishing project. We offer free test runs of your parts in our laboratory to assist in this manner. When finished, we return the parts for your evaluation.
