Media Consumables

Mass-Finishing Compounds

The chemical environment in which metal parts are cleaned, cut, abraded, smoothed and de-burred is controlled entirely by the compound and water solution. "Solution" is the key word, since water makes up over 80% of most of these solutions. And the water itself is important. Variations just in water hardness, for example, can make a compound that is excellent in one locale useless in another.

A poor choice of compound or poor control of its solution flow rate or concentration can materially increase time to do the work, can alter final surface roughness and the color of the parts, their cleanliness, and the tendency of metal parts or metal media to rust or oxidise.

The best compound in the world for a given application cannot work if the concentration at which it is used is too low or too high. Many of the ingredients in these products are surface active—they work on surfaces and interfaces between metal and solution, media and solution, metal and air, solution and air, and so on. Surface-active materials have a characteristic minimum threshold concentration, below which they are almost completely ineffective.

Mass-Finishing Media

In a mass-finishing process, an important function of the media is to separate parts in order to control part-to-part contact.

Abrasive media is the cutting tool in mass finishing. Very aggressive media cuts metal rapidly and removes rough surfaces quickly. Finer abrasive media cut at a slower rate and can further refine rough surfaces to reduce surface roughness prior to plating or painting.

Preformed ceramic and preformed plastic media are the most popular abrasive.

Non-abrasive media can put a bright or even a color-buffed finish on the parts. Preformed, hardened steel media is very popular because it is fast and clean. Non-abrasive ceramic pre-forms and hardwood media fill other application requirements, the latter even polishing plastics.
