The parts that need to be polished are placed in a "drum” with deburring or polishing chips. The various types of movements produced create an abrasive and polishing effect. This operation, known as trowalising or tribofinishing, is suited for delicate and intricate parts with a weight ranging from a few micrograms to over 500 grams.
This sort of treatment can be used on all types of metal and also on certain types of plastic.
