LR Series Vibratory Finishing Bowls

The LR Series Vibratory Bowls are manufactured by our sister company, ALMCO. They are well-suited for both through-feed and batch processing of parts and have a built-in internal separation system. LR stands for “long radius,” as these bowls have a large working channel, ideal for finishing delicate or long and narrow parts.

LR Series Basic Operation

The LR Series vibratory bowl functions through a vibrating motion that enables small abrasive media to interact with parts for finishing. The bowl is loaded with a blend of media, water, and compound that assists in the finishing process, and the parts are positioned close to the discharge screen. While the bowl vibrates, the media in the mixture grinds against the parts, ensuring a consistent and uniform finish. After the parts complete a pass around the bowl, an internal separation system separates them from the media.
