The vibrofinishing of the metals, or tumbling, is a process that helps the elimination of burrs or melting residues of the product making it uniform, free of any imperfection and ready for the following phases.
Vibratory finishing is achieved by using special machines similar to round tanks that trigger a vibration. In these roto-barrels, ceramic or other abrasives are added and once inserted, the product to be processed is treated for a time that can vary according to the piece and its surface.
In certain cases, liquids are also used during processing which facilitate production or prevent any oxidation of the product.

Types of vibratory finishing

Vibratory finishing can be divided into two types:

Wet-processed

This is the most commonly used process; it is performed in roto-barrels with ceramic abrasives or other types and different liquids.

Dry-processed

It is the same process as wet tumbling but in this case neither ceramic nor liquid abrasives are used. The products inserted "collide" with each other, eliminating imperfections without any external help.

Different types of abrasives and different times are used based on the material to be finished.
S&G has various roto-barrels with different abrasives in order to offer the customer the preferred finishon any material.
