What’s Electroplating? Definition, How It Works & Applications
Finishing the machined or manufactured components using the appropriate method ensures their longer durability. It is also critical for the...
Polishing is a surface finishing process used to smooth and refine CNC machined and sheet metal parts by mechanically removing minor tool marks, scratches, and surface imperfections. Using abrasive belts, wheels, or compounds, polishing improves surface smoothness and creates a clean, uniform appearance ranging from satin to mirror-like finishes. It is commonly applied after machining to enhance both visual quality and touch feel, especially for customer-facing or functional components.
This finish is widely used for aluminum, stainless steel, brass, and other metals where aesthetics, corrosion resistance, or reduced friction are important. Polishing does not significantly change part dimensions, making it suitable for precision components with tight tolerances. In CNC machining and sheet metal fabrication, polishing is often selected for enclosures, brackets, housings, and decorative parts that require a smooth, professional finish before anodizing, coating, or final assembly.
