What is polishing & finishing?
Polishing and finishing are controlled processes used to improve the surface quality of metal components by removing imperfections, refining surface texture and achieving the required finish.
These processes are essential where surface condition affects performance, coating adhesion or visual appearance.
Operating within our AS9100 quality system, all finishing processes are carefully controlled to ensure consistency, repeatability and protection of critical component features.
Typical polishing & finishing applications
- Removal of tooling marks and surface imperfections
- Preparation for coating, painting or anodising
- Cosmetic finishing for visible components
- Finishing of spun, machined and fabricated parts
- Removal of weld discolouration
- Surface refinement for performance-critical components
Polishing and finishing provide consistent, high-quality surface results, supporting both functional and aesthetic requirements in demanding engineering environments.
