Question 1

What is tumbled finishing?

Accepted Answer

Tumbling — also known as vibratory finishing — is a surface finishing process that uses abrasives and controlled vibration to smooth edges, reduce burrs, and uniformize the part surface.

Question 2

Does tumbled finish completely remove machining marks?

Accepted Answer

Not completely. The process helps soften small surface marks and improve visual uniformity, but deep defects or strong tool marks may still remain visible.

Question 3

Does tumbling affect part dimensions?

Accepted Answer

Dimensional impact is generally low, although the process may slightly round edges and corners depending on cycle time and abrasive used.

Question 4

Can it be combined with other finishes?

Accepted Answer

Yes. Tumbled finishing is often used before anodizing, paint, coatings, or additional cosmetic treatments to improve part surface condition.

Question 5

What materials can be tumbled?

Accepted Answer

The process is widely used on aluminum, stainless steel, steel, brass, and other machined metals compatible with vibratory abrasive media.
