Mass Finishing & Media Supply

Vibratory Finishing

Vibratory finishing uses controlled oscillation to process batches of components simultaneously, delivering consistent deburring, radiusing, cleaning, descaling, and polishing across every part in the load. Advanced vibratory bowls and troughs handle complex geometries — internal passages, undercuts, and intricate features — without compromising critical tolerances. This makes it the process of choice for high-volume runs where manual finishing would be impractical or inconsistent.

Rotary Finishing

Rotary barrel finishing provides high-energy mass finishing for components that require more aggressive material removal or heavier deburring. The tumbling action delivers excellent results on robust parts, achieving uniform edge breaks and surface improvements across large batch quantities with minimal operator intervention.

Why Mass Finishing?

Consistency at Volume Every component in the batch receives the same finishing action, eliminating the variability inherent in manual deburring and polishing. Whether you’re processing 50 parts or 5,000, the last part out matches the first.

Reduced Unit Cost Batch processing dramatically lowers per-part finishing costs compared to hand finishing or single-part machining operations. Less labour, less handling, faster throughput.

Preserved Tolerances Mass finishing removes only what needs removing. Controlled media selection and process parameters ensure dimensional integrity is maintained, even on precision-machined and ground surfaces.

Complex Geometry Capability Parts with features that are difficult or impossible to reach by hand — recessed pockets, cross-holes, internal radii — are finished uniformly by the media flow.

Improved Surface Integrity Beyond cosmetics, mass finishing removes stress risers from machined edges and surface imperfections, contributing to improved fatigue performance and reduced risk of crack initiation in service.

Faster Turnaround Automated batch processing means shorter lead times. Parts go from machined to finished faster, keeping your production schedule moving.

Media Supply

We supply premium abrasive media and polishing compounds matched to your material, geometry, and finish requirement. Getting the media right is half the process — the wrong choice means wasted cycle time, poor finish quality, or unnecessary material removal.

Ceramic Media High-density ceramic media delivers aggressive cutting action for fast deburring and radiusing on harder materials — steels, stainless steels, and aerospace alloys. Available in a range of shapes and sizes to reach complex part features.

Plastic Media Lighter and less aggressive than ceramic, plastic media is suited to softer materials — aluminium, brass, zinc die-castings — and applications where a finer finish is needed without risk of surface damage or excessive stock removal.

Polishing Compounds We supply a range of liquid and paste compounds formulated for specific material and finish combinations — from heavy-cut deburring compounds through to high-gloss finishing solutions.

Process Development & Media Recycling Our in-house expertise goes beyond supply. We work with you to develop and optimise your finishing process — selecting the right media, compound, and cycle parameters for your parts.
