Mass Finishing

Mass finishing is a surface finishing process used mainly for metallic workpieces. It is a common operation prior to electroplating, painting, anodizing and other processes to improve surface finishes and for deburring and cleaning parts because it's easy to do, reliable and low in cost. Mass finishing technology has continually evolved to meet the demands of various industries that require consistently produced, often intricate parts. At present, it is widely used in the medical implant industry for the grinding and polishing of artificial knees and hips, automotive parts producers for superfinishing gears, and various applications in aero-engine componentry. Alfa Chemistry has been a recognized industry leader in plating services, and we are intimately familiar with all aspects of the modern mass finishing process. When you need to polish, deburr or radius parts after manufacture and prior to final plating, Alfa Chemistry is your first choice.

Mass finishing equipment

We have many types of equipment for mass finishing, including round vibrators, tub vibrators, spindle machines, centrifugal barrels, and so on.

01

Round vibrators

Round vibrators are the most popular type of mass finishing equipment. They are easy to use and automated, and can be adjusted to process parts of various shapes and sizes.

Tub vibrators

Tub vibrators are often used when it comes to very long parts, or when multiple media are required, or when machine costs must be minimized.

Spindle machines

Spindle machines are renowned for their effectiveness in deburring gears and polishing die castings and other high-quality materials with precision and efficiency.

Centrifugal Barrels

Centrifugal barrels are effective at making rough surfaces exceptionally smooth and can also process fragile parts with gentle precision.

Common types of mass finishing media

In mass finishing, media is introduced to accomplish four main actions (cut, luster, part separation and surface scrubbing). Common types of mass finishing media are as follows:

  • Steel media
  • Organic media
  • Aluminum media
  • Preformed ceramic media
  • Natural random-shaped media
  • Plastic or preformed resin-bonded media
