Tumbling, barrel finishing, is the process of improving the surface of a raw metal part. Through the tumbling action one can accomplish deburring, corner rounding, burnishing, polishing, etc. There are two types – wet or dry tumbling.
For small parts this process has an economical benefit versus traditional hand finishing. In addition, large quantities of parts can be processed at one-time.
Some benefits of this process are:
- Reduced cost
- Improved time to market
- High polish finish
- Longer-lasting parts
