Barrel Finishing

Name:
Barrel Finishing
Detailed information:
Cleaning, smoothing, and polishing of metal or plastic items by mechanical friction obtained by placing them in drums or barrels that rotate on their horizontal axis. An abrasive medium and water are usually added. The barrels are six- or eight-sided, and often contain vertical dividers to make two or more compartments that can be individually loaded and unloaded. Such treatment is widely used for large-scale cleaning and burnishing of metal parts, which it finishes to exact dimensional tolerances much more economically than is possible by manual methods.
