Product Description

Electrochemical Polishing Technology
Deep holes and blind grooves polished thoroughly in one step!
Medical-grade stainless steel electrochemical polishing, 100% mirror finish with no dead corners on complex-shaped parts.
Salt spray corrosion resistance 2400h+ | Compliant with ASTM F86 / ISO 13485
Precision treatment of internal threads, micro-holes,
multi-curved surfaces with surface roughness Ra ≤ 0.08 μm
Electrochemical polishing is an electrochemical surface finishing process where the metal workpiece acts as the anode immersed in a specific electrolyte. When current passes through, selective anodic dissolution removes microscopic surface protrusions, achieving surface leveling, brightening, and performance enhancement.

Before Electrochemical Polishing

After Electrochemical Polishing

Outstanding Surface Smoothness
Can reduce surface roughness (Ra) from 1.6 μm to 0.05 μm (mirror finish), eliminating scratches and embedded abrasives caused by mechanical polishing.

Significant Corrosion Resistance Improvement
Dissolves surface iron impurities and defects, forming a chromium-rich passive film (stainless steel),
increasing salt spray test duration
by 2–5 times.

Uniform Treatment for Complex Structures
Non-contact process can reach deep holes, inner walls, threads, and other areas difficult for mechanical polishing.
Uniform current distribution → High overall surface consistency.

Micron-Level Precise Material Removal
Removes 5–40 μm of surface material in a controlled manner,
avoiding dimensional deviations (compared to mechanical polishing which can over-cut).

Biocompatibility and Cleanliness
Eliminates micro-cracks on the surface → Compliant with GMP/FDA medical standards.
Ultra-low adsorption: surface energy reduced → particles/liquids do not easily adhere.

No Mechanical Stress Introduced
No heat-affected zone or work hardening → Preserves the original mechanical properties, especially suitable for precision parts and thin-walled components.
