Mass finishing(tumbling) allows you to finish the entire surface of several places at the same time. Jewelry items are placed in a container or drum along with polishing media and a polishing compound(a specicialize soap made for working with metals]. The machine rotates, tumbles or vibrates the container, creating steady, repitive motion that polishes the metal.

Characteristic
·Mono-drive，fan-cooled machines run quietly
·Clear blows offers easy load preparation
Notice
→Steel media is the easiest to use andis available in diameter of 3mm，4mm and 5mm to produce different finishes.
→Magnetic finishers work with a strong magnet inside their bases that rotates，pulling magnetic steel media through the compound，polishing the jewelry pieces.
→Magnetic finishing is the fastest of these mathods and is ideal for textured pieces but can leave”ping’marks on your pieces if run too long.
