Part-on-Part Mass Finishing, Part 2 – Rotary Vibrators Versus Centrifugal Disk Machines

As described in Part 1 of our Part-on-Part Blog Series, some forms of mass finishing techniques encourage part-on-part contact to achieve the desired finish. 

In addition to viewing work piece impingement as an asset, this type of mass finishing also eliminated the need for ceramic, plastic, and other types of media. The only additives required for such part-on-part finishing are water and the respective compounds.

Rosler Metal Finishing designs and manufacturers two machines specifically for part-on-part mass finishing known as WTA rotary vibrators and MK centrifugal disk machines.

The applications and benefits of each machine provide a range of part-on-part mass finishing uses for sturdy parts in bulk. Let’s compare their designs.

WTA Rotary Vibrators

Rosler developed special WTA rotary vibrators especially for part-on-part processing. These machines not only allow running the finishing/washing process, but also the subsequent drying stage in one single machine.

Part-on-Part Mass Finishing, Part 1 – Utilizing Work Pieces as the Media

Mass finishing processes require pressure and constant rubbing to achieve the desired finishing results. In most cases, these applications require media specifically selected for its material, size, and shape to act upon work pieces and achieve the required effects. Some mass finishing applications also seek to eliminate or reduce part-on-part impingement or contact to protect delicate and high-value work pieces.

Conversely, part-on-part mass finishing intentionally exposes work pieces to impingement and encourages contact between work pieces and the resulting pressure to create finishing effects without the need for ceramic, plastic, and other types of media. The only additives required for such part-on-part finishing are water and the respective compounds.

Rosler Metal Finishing designs part-on-part mass finishing machines, known as WTA machines, which help reduce cost per piece through the elimination of media consumption and faster processing times.

Ideal Work Pieces

Part-on-part finishing is ideal for small, bulk parts that are made of brass, steel, aluminum, and even small ceramic components.
