TUMBLING MEDIA

Many sizes, shapes and compositions are available to suit your specific application. Low density light weight media (65-70 lbs./cu. ft.) is suitable for a wide range of operations such as burr removal, edge breaking, or surface preparation prior to plating or buffing. Higher density media (90-95 lbs./cu. ft.) is more aggressive, faster cutting and can reduce cycle times. It is used for fast or ultra-fast cutting. Plastic media is polyester resin bonded. Synthetic media uses a urea formaldehyde resin which minimizes foaming and reduces residue on parts.
