Design Considerations

Electropolishing Design
Considerations

  • Use stainless steel 304 or 316 for consistent electropolishing and corrosion resistance up to 90%.
  • Target Ra 0.6–0.8 μm to achieve uniform polishing and mirror-like surfaces.
  • Account for 10–50 μm material removal per surface on critical dimensions.
  • Apply minimum 0.5 mm radii on internal corners to prevent uneven electrolyte flow.
  • Ensure 95% of part surfaces are exposed to solution for uniform material removal.
Applications

Electropolishing Material Applications for Robot Parts

  • Improves Corrosion Resistance Icon

    Improves Corrosion Resistance

    Smooths the surface at a microscopic level, reducing areas where corrosion can start.

  • Enhances Cleanliness and Hygiene Icon

    Enhances Cleanliness and Hygiene

    Creates a non-stick surface that resists bacteria and contaminants, ideal for medical and food-grade parts.

  • Produces an Ultra-Smooth Finish Icon

    Produces an Ultra-Smooth Finish

    Removes surface roughness, burrs, and micro-peaks for a clean, bright appearance.

  • Maintains Tight Tolerances Icon

    Maintains Tight Tolerances

    Removes material evenly and minimally without distorting part geometry.

Applications

Electropolishing Types and Applications for Robot Parts

Finish Purpose Thickness Wear Notes
Standard Electropolish Improve surface smoothness and reduce friction 10–50 μm material removal Low to moderate wear reduction Ideal for moving mechanical components and precision parts
Mirror Finish Achieve high reflectivity and aesthetic appeal 20–50 μm material removal Moderate wear resistance Often used on visible robot housings or consumer-facing components
Corrosion-Resistant Enhance corrosion protection in harsh environments 10–50 μm material removal Moderate wear resistance Recommended for stainless steel and titanium parts in humid or chemical-exposed environments
Cleanroom/Medical Minimize surface contamination and ease cleaning 10–30 μm material removal Low wear Suitable for cleanroom robots, medical, or food-grade robotic components
High-Precision Maintain tight tolerances while polishing 10–30 μm material removal Low wear Best for joints, gears, and components with critical dimensions
