OR Series Vibratory Finishing Bowls

The OR Series Vibratory Bowls are manufactured by our sister company, ALMCO. It is the only vibratory bowl with dividers available, allowing operators to separate parts into different compartments. The ability to separate parts prevents part impingement and eliminates the need for fixturing, which is ideal when finishing sensitive parts.

OR Series Basic Operation

The OR Series vibratory bowl utilizes a vibrating motion that enables small abrasive media to come into contact with parts for finishing. It is fitted with a rotating divider that provides multiple compartments for parts handling. The bowl is filled with a mixture of media, water, and compound to aid in the finishing process. Featuring a natural contour molded urethane-lined tub, the OR Series ensures that parts are fully immersed in the mass and are subjected to a thorough deburring while both the media and parts rotate in an upswept angular clockwise movement. Parts are loaded and unloaded from the rotating mass without the need to stop the machine.
