Mass Finishing Demystified: A Comprehensive Guide to Vibratory Finishing


Vibratory finishing has become a prevalent mass finishing process for its versatility and efficiency. While some may equate mass finishing solely with vibratory finishing, other methods include centrifugal barrel, centrifugal disc, and rotary barrel machines, as well as specialized surface finishing machines.


Vibratory finishing takes place in a vibratory bowl or tub, where components undergo surface deburring, polishing, smoothing, cleaning, descaling, rust removal, and radiusing. The first tub-type vibratory finishing machine was introduced in 1957, by the bowl-type machine in 1962.


Essential Processes in Vibratory Finishing:

1.1 Deburring

Deburring is a widespread application in vibratory finishing. It usually involves a mild compound with a pH around 7.0 and general performance ceramic media. Deburring can clean machining oil or lubricant while leaving a clean surface for assembly and handling.

1.2 Burnishing

Burnishing is commonly done with steel or zirconia balls. Steel media is popular for its shape versatility, while ball cone-shaped steel media is excellent for dull edges. The choice of burnishing compound and cleaning media is crucial for optimal performance.


1.3 Smoothing

The smoothing process can alter surface properties based on the type of media used. Ceramic media provide an economical way to achieve a pre-painting finish, while plastic media is suitable for softer metals. In some cases, increased surface roughness is desirable, such as for automotive friction pads.


1.4 Cleaning and Degreasing

Vibratory finishing machines are ideal for cleaning oily and greasy parts. The process requires a strong acidic compound to remove fatty and oily substances from the metal surface. Cold water is preferred to prevent premature wear on the PU lining.


1.5 Rust Removal

The vibratory finishing process must eliminate the oxide layer for a smooth surface before further processing. Rust removal typically involves ceramic media with strong cutting power and a cutting compound to reduce processing time.


1.6 Radiusing

Radiusing, or edge rounding, makes part edges round and smooth, protecting users from injury and making handling easier. Radiusing often occurs alongside deburring and surface material removal in vibratory finishing.


Key Elements in Vibratory Finishing

The interaction between parts, media, compound, and equipment is critical to the success of vibratory finishing.

2.1 Parts

The part size determines the appropriate vibratory finishing machine. Small parts, such as pins and tabs, often require a vibratory bowl finishing machine, while larger parts like transmission gears may necessitate a vibratory tub.


2.2 Equipment

Various vibratory finishing machines are available, including curved wall, straight wall, and machines with internal separation decks. Choosing the right machine depends on part size and processing requirements.
