Buyer resource
Surface finishing requirements should be reviewed together with the part drawing, material, functional surfaces, cosmetic expectations, inspection needs, and packaging notes. Clear finish information helps buyers and suppliers discuss the machining and finishing route before quotation.

Aluminum machined parts may include anodizing requirements for appearance, surface protection, or application-specific needs. Buyers should specify the required finish note, color or appearance expectation if applicable, masking areas, cosmetic surfaces, and functional surfaces without assuming every color or film thickness is available.
Stainless steel passivation and plating-related requirements should be described with the material, drawing note, standard if required, contact surfaces, threaded features, and documentation expectations. These details help the supplier review whether the finish requirement is practical for the part geometry.
Black oxide, bead blasting, polishing, and deburring are common finish discussions for CNC parts. The RFQ should clarify appearance expectations, burr-sensitive edges, visible surfaces, and whether the finish is cosmetic, functional, or mainly for handling and assembly.
Sealing faces, sliding surfaces, bearing locations, mating faces, visible surfaces, threaded areas, and assembly contact points may need different finish expectations. Marking these surfaces on the drawing reduces ambiguity before machining and finishing are reviewed.
Surface finish requirements may affect inspection, scratch protection, packaging, labeling, and shipment handling. If a part has cosmetic surfaces or finish-sensitive features, the RFQ should describe packing and handling expectations early.
A useful finish discussion includes the material, finish name, drawing note or standard if available, appearance expectation, masking areas, critical surfaces, quantity, inspection needs, documentation requirements, and packaging notes.
