Abrasive Media for Mass Finishing
Abrasive media does the actual work in every mass finishing process. The right media shape, size and grade determines how fast burrs come off, how much material is removed, and what final surface texture you get. We supply the full range: ceramic, plastic, resin, steel, porcelain, walnut shell and corn cob media.
Ceramic media delivers aggressive cutting for heavy deburring and grinding of ferrous parts. Plastic and resin media give gentle radiusing and polishing on soft metals such as aluminium, brass and zinc. Porcelain and steel media burnish to a bright finish, while organic media dry and polish without scratching.
Media is available in triangles, stars, balls, cones, cylinders, wedges and custom shapes from 2 mm upward. Send us your part drawings and material and our engineers will recommend the media mix that finishes fastest at the lowest cost per part.
Frequently Asked Questions
How do I choose the right mass finishing media?
Match media by three factors: material hardness, part geometry and the finish target. Ceramic media cuts fast on hard metals and heavy burrs; plastic and resin media produces finer finishes on softer metals; steel media burnishes without cutting; organic media polishes delicate parts dry. Media shape also matters, since rounder shapes polish while angular shapes cut.
What shapes of abrasive media are available?
Common shapes include triangles, cylinders, balls, cones, stars, pyramids, angle-cut triangles and three-pointed forms. Angular shapes reach into recesses and cut faster, while round and spherical shapes burnish and polish more gently. We help select shape and size so media reaches every feature without lodging in holes.
How often should finishing media be replaced?
Media wears down as it works, so it should be replaced when it is roughly 30 to 50 percent smaller than its original size, or when cutting action drops noticeably and cycle times stretch. Maintaining the correct media-to-part ratio is one of the most effective ways to keep finishing results consistent.
