Precision Metal Polishing

Axium offers a complete range of surface finish options including manual polishing, electropolish and bead-blast. From mirror finish to dull polish, our core expertise is in high-specification precision polishing, we are one of the few companies that process stainless steel and associated metals to a specific surface finish and precise dimensional tolerance.

Process control

Manufacturing pharmaceutical, biotech and other specialist components involves careful planning, so that hygienic surfaces which become inaccessible on the finished article are still in compliance. In such cases a component could pass between manufacturing and polishing several times before it is finished. At each stage it is essential to meet the target specifications for surface quality and dimensional accuracy. Qualified inspection engineers using calibrated measuring equipment document the appropriate evidence so detailed reports and comprehensive certification packs can accompany the completed item.

Materials control

To conform with the European Directorate for the Quality of Medicines and FDA requirements for TSE Compliance Certification (Transmissible Spongiform Encephalopathy) all polishing compounds and cutting oils used at Axium Process are certified animal by-product free.

Bead blast

Different grades of abrasive beads can be used in our blast cabinet to achieve a wide variety of surface finish options.

Weld Dressing

Internal and external welds are ground to match the parent metal surface and become completely invisible, many of our fabricated components appear to be made from a single piece!

Electropolishing

Axium’s on-site electropolishing service is used for many applications throughout the pharmaceutical, food, beverage and aerospace industries
