Polishing Overview
Polishing mechanically smooths and refines parts by removing minor tool marks, scratches, and surface imperfections. Abrasive belts, wheels, or compounds create a clean appearance ranging from satin to mirror-like finishes. It is used on CNC machined and sheet metal parts, including enclosures, brackets, housings, and decorative components, and can prepare surfaces for anodizing, coating, or final assembly.
- Improved appearance:
A smooth, uniform finish enhances customer-facing parts.
- Smoother surfaces:
Polishing reduces minor surface imperfections and can make parts easier to clean.
- Finish options:
Choose from basic, fine, and mirror polishing according to material and appearance requirements.
- Surface preparation:
Polishing can prepare parts for plating, anodizing, or coating.
