Why Source CNC Parts from Vietnam?
Vietnam's CNC machining industry has matured dramatically over the past decade. What was once limited to basic turning and drilling has evolved into a sophisticated manufacturing ecosystem with 5-axis capabilities, Swiss-type lathes, and EDM wire cutting — all at costs significantly below Chinese equivalents.
With US Section 301 tariffs holding at 25% on Chinese manufactured goods and showing no signs of reversal, the cost advantage of Vietnam has become impossible to ignore. Our clients typically see total landed cost savings of 40–60% when switching CNC work from China to Vietnam.
DEWIN's role is simple: we've already done the factory vetting. We maintain relationships with 50+ CNC facilities across Vietnam, each audited for equipment quality, QC processes, and delivery reliability. You get the pricing of a local buyer with the quality assurance of an international procurement team.
Our CNC Machining Capabilities
3-Axis & 4-Axis CNC Milling
For most prismatic parts, housings, brackets, and plates. Our factories run Haas, Mazak, and Fanuc machines with automatic tool changers for unattended operation.
5-Axis CNC Milling
Complex geometries, aerospace components, and medical implants. DMG Mori and Hermle 5-axis centers with probing for in-process verification.
CNC Turning & Swiss-Type Lathes
Shafts, pins, bushings, fittings, and connectors. Citizen and Star Swiss lathes for small-diameter, high-precision turned parts.
EDM & Wire EDM
Hardened tool steel components, intricate slots, and fine features that conventional milling can't reach. Sodick and Mitsubishi EDM machines.

Frequently Asked Questions
What tolerances can Vietnam CNC shops achieve?
Our vetted factories routinely hold ±0.005mm on critical dimensions. For ultra-precision work, we have partners with ±0.002mm capability using temperature-controlled environments and high-end Mazak/DMG Mori equipment.
What materials do you machine?
Aluminum (6061, 7075, 2024), stainless steel (303, 304, 316), carbon steel, titanium (Grade 2, Grade 5), brass, copper, Delrin/POM, PEEK, nylon, and more. If you have a specific alloy, ask — we likely have a supplier for it.
What's the minimum order quantity?
No strict MOQ. We handle single prototypes through to 100,000+ production runs. For very small batches (1–10 pieces), lead times are typically 5–7 business days.
How much cheaper is CNC machining in Vietnam vs China?
Typically 20–40% less than Chinese factories for equivalent quality, before tariff savings. When you factor in the 25% Section 301 tariff on Chinese goods, the total savings can exceed 50%.
Do you offer surface finishing?
Yes — anodizing (Type II and III), nickel plating, zinc plating, powder coating, bead blasting, brushing, polishing, and passivation. All done in-house or at co-located finishing partners.
How do you ensure quality?
Every order includes dimensional inspection with CMM reports. We offer PPAP documentation, FMEA, first article inspection (FAI), and AQL-based sampling for production runs.
