Kramer Industries Inc. > Barrel Finishing Systems


Barrel Tumblers are the most versatile type of parts finishing system. Applications can range from heavy deburring to high polishing to degating to parts drying. Barrel sizes range from as small as a few ounces to as large as a small car and everything in between.

The barrel tumbling process slowly rolls and cascades the load in the barrel to accomplish the desired task. Tumbling can be done either wet or dry and with or without a media. Screens are used to drain water and to separate media and parts.
