Welcome to FLYcncpart's mirror polishing service! Through precision mechanics and handcraftsmanship, we create a mirror-like finish for your parts. Our Shenzhen team ensures high-quality finishes to meet the needs of high-end applications.
Description: Mirror polishing combines mechanical polishing with meticulous handwork, using diamond or aluminum oxide paste, achieving a roughness of Ra 0.01-0.1μm. The process includes coarse grinding (120-600#), fine grinding (1000-3000#), and mirror polishing (specialized wheels). The process takes 1-6 hours and requires multiple stages.
Applicable Materials: Metals (such as stainless steel, aluminum, and copper) and certain hard plastics.
Visual Appearance: A mirror-like, high-gloss surface with clear reflections, suitable for high-end decorative or optical applications.
Advantage
Extremely high finish: Surface reflectivity reaches over 90%, approaching a mirror-like finish.
Improved Corrosion Resistance: A smooth surface reduces corrosion spots and extends lifespan.
Aesthetics: Provides a high-end appearance, suitable for jewelry or automotive parts.
Functionality: Reduces friction, suitable for precision mechanical components.
Compatibility: Suitable for complex geometries and meeting custom requirements.
Pollution-Free: Mechanical polishing leaves no chemical residue, making it environmentally friendly.
Precautions
Progressive grit grading: From coarse grit (120#) to ultra-fine grit (3000#) to avoid skipping grades and scratches. Uniform Pressure: Mechanical and manual polishing must be consistent to avoid over-polishing; test tolerances.
Thorough Cleaning: Remove polishing residue to prevent contamination in subsequent processes.
Design Considerations: Avoid sharp corners and deep holes, and plan the polishing path.
Quality Standards: Comply with ASTM B912 or ISO 10110, and check Ra values and reflectivity.
Safety Measures: Wear protective equipment and control the splashing of paste and dust.
