Corundum Media ACC – Ceramic Deburring Media
Corundum Media ACC is a high-cutting, high-density ceramic abrasive media made by HuaTong Polish from premium non-recycled corundum sand and a ceramic binder. Each oblong (ACC) piece is sintered at high temperature for maximum toughness and a consistent, aggressive cutting edge — ideal for fast deburring, deflashing and descaling of metal workpieces in tumbling and vibratory mass finishing.

Applications
Corundum media is engineered for the deburring, deflashing and descaling of ferrous and non-ferrous metal parts — automotive components, fasteners, castings, stamped parts and CNC-machined items. Its strong cutting action quickly removes burrs and flash before polishing, plating or coating.
Why Choose HuaTong Corundum Media
- Extremely strong cutting force for fast stock removal and cycle-time savings.
- Consistent quality from virgin, non-recycled corundum sand.
- Multiple shapes and sizes for vibratory bowl, tub, disc and centrifugal finishers.
Tip: for a more refined, brighter finish after deburring, pair with Polishing Media SCC.
Frequently Asked Questions
Which machines can use corundum ceramic media?
Corundum ceramic media works in standard vibratory bowl and tub finishers, centrifugal disc finishers and barrel tumblers, provided the mesh size fits the workpiece geometry.
Can corundum media be used for polishing?
Corundum media is primarily a cutting/deburring media. For bright polishing and scratch repair, use a high-alumina finishing media such as Polishing Media SCC.
How much media should I load?
A typical ratio is about one part media to one part workpiece by volume. Send your part or drawing to HuaTong for a load recommendation.
