What is Rotary Tumbling? Rotary tumbling is a proven mass finishing technique for burnishing or cutting surfaces. Effects are achieved over a period of several hours or even days, as tumbling is the slowest of all the mass finishing techniques, but capacity for dollar spent is the greatest. Use steel media with detergent compounds to burnish and work-harden pieces or use plastic media with detergents for aggressive cut-down.

Pros:

Shines and Burnishes Surfaces

Cons:

Slowest mass finishing technique. Not for final polish on broad flat surfaces.
