Welcome to FLYcncpart's hand-polishing service! Through exquisite handcrafting techniques, we provide your parts with a smooth, glossy surface, enhancing both their aesthetics and functionality. Our Shenzhen team ensures perfection in every detail with their professional skills.
Description: Hand polishing is a manual process that uses sandpaper, polishing paste, and a cloth wheel to gradually refine the surface to a roughness of 0.1-0.8μm Ra. The process includes coarse grinding (80-400# sandpaper), fine grinding (600-1500#), and polishing (specialized paste). Processing time ranges from 30 minutes to several hours, depending on part complexity.
Applicable Materials: Metals (such as aluminum, stainless steel, and copper), plastics, and wood.
Visual Appearance: A smooth, semi-gloss or silky finish with subtle texture, suitable for decorative parts.
Advantage
High Flexibility: Able to process complex shapes and localized areas, suitable for small batches or custom parts.
Surface Smoothing: Effectively removes scratches and burrs, enhancing the finish.
Affordable Cost: Manual operation avoids expensive equipment, making it suitable for prototypes or repairs.
No Heat Damage: Low-speed polishing prevents material deformation and maintains tolerances.
High Aesthetics: Provides a soft gloss and hides minor imperfections.
Versatility: Suitable for a wide range of materials as a pre-treatment or final finish.
Precautions
Force Control: Manual application requires uniformity to avoid over-polishing; test for wear resistance.
Grit Selection: Progress from coarse grit (80#) to fine grit (1500#) to avoid scratches.
Thorough Cleaning: Remove polishing residue to prevent contamination in subsequent processes.
Design Considerations: Plan edge and groove treatments to match part curvature.
Quality Standards: Comply with ASTM B912, inspecting surface roughness and gloss.
Safety Measures: Wear gloves and goggles to control dust and paste splashing.
