How to Repair a Vibrating Tumbler

Vibratory tumblers utilize high frequency vibration and abrasive media grit to clean and polish metal parts. The vibrating action combined with rust-cutting grit scrubs corrosion from surfaces of small components without affecting detail or rounding edges. Use of more abrasive media can also remove burrs and flash from newly cast parts and stampings. By adding shine media to the tumbler bowl, tumbled metal objects receive a lective shine. Tumbler defects or inconsistent results can usually be traced to placing an improper component load on the tumbler and bowl or incorrect use of abrasive media.

Instructions

1

Inspect the tumbler bowl for holes or other signs of excessive wear. Make sure you are using wet abrasive media in the bowls of a standard vibratory tumbler. Dry media may prematurely wear out the tumbler bowl.

2

Verify that the tumbled components do not exceed the manufacturers recommended size for the tumbler. Oversize parts may damage the bowl or overload the motor. Also confirm that the correct ratio of 70 percent media to 30 percent parts for a standard vibratory tumbler is observed.

3

Allow additional time in the tumbler if parts are emerging with a dull finish or with incomplete de-burring or smoothing. Continuous running time for these processes ranges from three hours up to 24 hours. Make sure no steps are skipped in the sequence of cleaning parts and adding media to the bowl.

4

Observe proper degreasing methods if the tumbler is leaving excessive rust deposits in recesses of any parts.Try adding a commercially available metal wash for vibratory tumblers to the bowl. Make sure the proper proportion of water is added to the rust cutting media or interrupt tumbling at intervals to remove parts and rinse.

5

Optimize the use of abrasive media. Allow wet media to dry thoroughly before returning it to storage. Reuse cutting media only until it no longer cuts or polishes in an acceptable amount of time.
