Tumbling Media

TUMBLING MEDIA FOR BARREL & VIBRATORY FINISHING EQUIPMENT

In the tumbling process, a preformed media is a rigid agent that abrades the given part and removes the unwanted material. The advantage of tumbling media is the inclusion of a bonding agent that continuously recedes and exposes more abrasive particles. As a result, they maintain a relatively consistent removal rate over at least half the size of their shape.

Your desired surface finish determines the needed characteristics of your chosen media, such as size, shape, internal particle size, and mineral composition. Oftentimes, 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.

When considering tumbling media for aluminum, the choice of media is critical when trying to achieve a specific finish without damaging the aluminum, which is a relatively soft metal. Tumbling media for aluminum should be selected to ensure it has the appropriate level of aggressiveness but is not too aggressive or abrasive to the aluminum parts. This is where understanding the properties of tumbling media for aluminum comes into play. The media composition or bond needs to be appropriate to tumble the aluminum with delicacy yet effectively, preventing any undue metal removal or warping of the parts. The tumbling media for aluminum is not just about abrasion; it’s about achieving the finish needed while preserving the surface quality and tolerances of the aluminum
parts.

Tumbling media is a preformed abrasive material that is used for finishing and polishing parts made of various materials. It is mainly used with finishing equipment so that tumbling media and parts scrub against each other, producing thorough and precise abrasiveness to remove burrs.
