Coordinate machining requirements with the anodized finish
Anodized aluminum components need both a machining drawing and a clear finish requirement. State the aluminum alloy and condition, the required anodizing type or specification, appearance and any masked areas. If the part mates with another component, identify which dimensions must be accepted after treatment.
For process options, see surface finishes; for material context, see the aluminum material overview. This page focuses on coordinating the CNC part and finish as one project scope.
Features to mark before requesting a quote
- Critical bores, threads, fits, mating faces and datums.
- Surfaces to mask or treat differently.
- Dimensions to inspect after anodizing.
- Color, appearance and specification requirements.
- Quantity, finish records and delivery destination.
Alloy and process can affect the finished appearance and dimensions. Do not assume that one finish label applies to every grade or part. The requested specification and acceptance criteria should be confirmed before production.
