Elevate the quality and aesthetics of your parts with our precision polishing solutions.
Polishing at YUANYI is a precision finishing service that removes tool marks and micro-defects to achieve uniform gloss levels from satin to mirror. Using advanced polishing methods, we enhance appearance, reduce friction, and prepare surfaces for plating, anodizing, or coating. Suitable for metals such as aluminum, stainless steel, brass, and copper, our polishing ensures reliable quality for both prototypes and production.
Polishing refines machined surfaces by removing scratches, tool marks, and micro-burrs to reach a specified roughness and visual level—from uniform satin to high-gloss mirror. By smoothing surface asperities, it reduces friction and noise, improves mating and sealing behavior, and minimizes stress concentrators that can trigger cracks, enhancing wear, fatigue, and corrosion performance in service.
It also conditions the substrate for downstream finishing—creating clean, consistent surfaces that promote strong adhesion for plating, anodizing, coating, or bonding. Typical workflows combine staged abrasives with controlled pressure and feeds; critical faces can be masked and grain direction managed to protect tolerances and edges. Suitable for aluminum, stainless steel, brass, copper, and more, the process supports both prototypes and production parts.
