TUMBLING MEDIA FOR BARREL & VIBRATORY FINISHING EQUIPMENT

Our premium line of Treated Tumbling Media provides a variety of options for a superior surface finish. The term media describes any material used to modify or alter the appearance of a surface during a finishing process. Our Premium Treated Tumbling Media assure that no water or other added compounds are required for the process. These media are bases of Walnut Shell Grit, Corn Cob Grit, and others with added abrasives, lubricants, binders, and polishing agents.

In the tumbling process, a preformed media is the rigid agent that abrades the given part and removes the unwanted material. The advantage of this 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.
