Is it environmentally friendly?

Yes, no chemical waste is produced, and polishing compounds are recyclable.

How long does it take?

Typically 1–6 hours, depending on the complexity and desired gloss level.

Can it reflect images?

Yes, it has a high reflectivity suitable for optical-grade finishes.

Is it suitable for complex shapes?

Yes, but requires multiple stages of manual polishing.

What is the surface roughness range?

Ra 0.01–0.1μm, achieving an almost perfect mirror finish.

Processing Overview

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.
