Define the surface requirement first
Electropolishing services are a process-specific finish request, so identify the substrate, the surfaces to treat and the required specification. State the reason for the finish only where it is documented in the part requirements. Do not assume a generic process name establishes a surface roughness, cleanliness or corrosion result.
Account for geometry and material removal
Mark critical edges, small features, threads, bores and dimensions that may need review. Identify surfaces to mask and whether inspection occurs before or after treatment. Provide the material grade and current drawing revision so the process can be assessed against the actual part.
Make acceptance measurable
List the finish reference, any customer test or report, visual criteria and packaging. If the requirement has a numerical limit, put it on the drawing or specification with units and inspection method. Clarify which features are controlled and who approves any deviation.
For overall finishing guidance, see CNC surface finishing services. For chemical-film treatment, see Alodine coating services.
