Abrasive vibratory finishing medium
USF Surface Preparation Group

Surface Preparation offers a comprehensive range of mass finishing media. Mass finishing media (also called tumbling media) is available in numerous shapes, sizes and configurations. Media can be ceramic, plastic, metallic and even organic. However the two most common classifications of mass finishing media are Ceramic & Plastic.

Ceramic - Ceramic mass finishing media can be used for processes varying from heavy grinding applications to fine polishing processes.
Plastic - Typically plastic media is used for gentle surface finishing. Plastic mass finishing media is commonly used for softer, non-ferrous materials such as die castings.
Within each of these classifications mass finishing media can also be categorized by:

Composition - The composition of the media determines whether it is intended for heavy grinding, fine finishing or anything in between. Variables such as the bulk density (weight of media per cubic foot) and abrasive content within each composition are important factors in selecting which composition best fits your finishing requirements.
