Proof
Evidence you can request at RFQ
For milled parts, align CTQs (flatness/position) and the inspection report format before the first lot—this prevents approval delays.
Overview
What you get with SEMIX
CNC milling is ideal for parts with multiple faces, pockets, bores, and patterns that must hold relational accuracy. SEMIX supports precision CNC milling in Vietnam for customers who need stable execution, inspection evidence, and export-ready packaging.
- Prototype and NPI support for learning cycles and approvals.
- Repeat production with controlled processes and in-process checks.
- DFM feedback to reduce cost and risk before cutting metal.
Use cases
CNC milling applications
Parts with multiple faces, pockets, bores, patterns, and datums that must hold relational accuracy for assembly and alignment.
Tooling that supports calibration, test, assembly, and repeatable positioning—common in semiconductor and automation programs.
Milled parts with cross-holes, angled features, and tight positional control—supported by 4‑axis or 5‑axis strategies when needed.
Quick-turn prototypes for learning, then stable repeat builds with controlled processes and inspection evidence.
DFM guidance
Design tips that improve cost, yield, and lead time
Great CNC milling outcomes start with manufacturable design. During RFQ, SEMIX can provide DFM feedback to reduce risk and cost.
- Use practical corner radii to reduce tooling cost and improve surface consistency in pockets.
- Avoid deep, narrow cavities when possible; long tool reach increases vibration and can impact finish.
- Define datums and CTQs clearly so inspection is planned correctly and variation is controlled.
- Right-size tolerances: overly tight tolerances drive cost without improving function.
- Consider setup reduction using 4-axis or 5-axis if relational accuracy is critical.
Quality
How we protect accuracy
For precision CNC milling in Vietnam, quality is protected through planning and in-process control. We align measurement methods to your CTQs and reporting needs.
- Fixture strategy that stabilizes datums and reduces re-clamping error.
- In-process checks on CTQs to prevent drift and protect yield.
- Final inspection with reports structured for your receiving workflow.
RFQ checklist
Information that speeds up quoting
Accurate quotes require clear inputs. Use this checklist to reduce back‑and‑forth and shorten the time to a production‑ready plan.
- NDA (optional but supported) — sign your NDA or ours before file sharing.
- 2D drawing + 3D model (PDF + STEP/IGES), including revision level.
- Material and condition (grade, temper/heat treatment).
- Finish requirements (standard, color, thickness, masking).
- Quantity and schedule (prototype vs production, blanket PO, target ship date).
- Documentation (CoC, MTR, inspection report, first‑article package).
- Packaging (labeling, serials, kitting, clean handling).

FAQ
Service questions
Can you ship CNC milled parts to the USA and handle export documents from Vietnam?
Yes. We support export‑ready packaging and can align documentation (packing list, CoC, inspection reports) to your receiving workflow. Specify ship‑to details and any Incoterms/label rules in the RFQ.
What information do you need for a fast, accurate CNC milling quote?
Send a 2D PDF drawing + 3D STEP/IGES model, revision level, material/condition, finish spec, quantity, CTQs, and required documents (CoC/MTR/CMM report/FAI). Use our RFQ checklist.
Can SEMIX hold tight tolerances for precision machining in Vietnam?
We review tolerances case‑by‑case based on geometry, material, and inspection method. Highlight CTQs and GD&T so we can plan fixturing, process route, and reporting correctly.
Do you provide CMM inspection reports or first‑article documentation?
Yes—when required. Provide your reporting scope (CTQs vs full layout) and format expectations during RFQ. See Documentation Packages.
What finishes do you support for milled parts (anodize, passivation, plating)?
We coordinate common finishes through qualified partners based on your specification. Provide standard/type, color, thickness, masking requirements, and any certificate needs in RFQ.
How do you handle drawing revisions and engineering changes?
We confirm revision level during contract review and use controlled release of production files. If revisions change mid‑build, we align on impact to cost, schedule, and documentation before proceeding.
Do you support NDAs for U.S. buyer programs?
Yes. If your program is sensitive, we can sign your NDA or provide ours before you share CAD and drawings. NDA is handled in the first RFQ step.
