Part-on-Part Mass Finishing, Part 3 – Effective Finishing for Ammunition Work Pieces

The gun ammunition manufacturing process requires numerous finishing operations. Since ammunition parts allow for part-on-part mass finishing, Rosler Metal Finishing’s washing and drying machines are ideally suited for ammunition manufacturers.

Available as rotary vibrators and centrifugal disk finishing systems, Rosler’s part-on-part finishing machines can accommodate various ammunition pieces including blanks, cups, deep-drawn casings, cartridge primers, and bullets.

While the manufacturing step and finishing operation of each component varies by work piece and desired result, common mass finishing operations for ammunition based on the specific work pieces are summarized below.

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.
