A practical checklist to reduce risk when ordering tight tolerance CNC machined parts from overseas suppliers.

Tight tolerance parts require alignment between drawing, machining process and inspection. The more precise the requirement, the more important communication becomes.
Before placing an order, buyers should confirm datum, inspection method, quantity, material certificate and surface finish requirements.
Start with the function of the part. If a dimension affects assembly, sealing, motion or alignment, it deserves more attention than a purely cosmetic feature.
A clear drawing and honest discussion often reduce cost better than forcing every supplier to quote blindly. ANOK reviews tolerance, material, finish and delivery requirements before production.
