The mechanical process of refining the surface of a product by tumbling work in a suitable media is a long established finishing process. Generally, the work is placed in a barrel or vibrating tub with an abrasive media which can be anything from coarse ceramic abrasives to highly polished steel balls resulting in either metal removal or polishing. The process is most often wet, with chemicals added to the process to assist in the finishing.
Our equipment ranges from small rotating barrels to large vibrating tub machines which give us the ability to process anything from small to large parts.
Although the processing times can run into hours, it is a very efficient, low cost method of mechanical finishing. Near any metal can be treated by this process. Plastic or ceramic components can also be polished.
The finish achieved by this process may be the final finish or followed by subsequent finishing, such as anodising or e-coating.
