CNC Milling Services Vietnam
TDB Hanoi provides precision CNC milling services in Vietnam for custom metal and engineering plastic components manufactured according to customer drawings and specifications.
We support international customers from prototypes and low-volume requirements through repeat production, combining drawing review, process planning, CNC milling, quality inspection, secondary processes, and export-ready manufacturing support.
With 50+ CNC machines, TDB Hanoi provides flexible machining capacity for custom components requiring reliable quality and consistent production.
Precision CNC Milling for Custom Parts
CNC milling is widely used to manufacture components with complex geometries, precision surfaces, holes, pockets, slots, and other machined features.
Our CNC milling capabilities support components requiring:
- Pockets and cavities
- Slots and grooves
- Precision holes and bores
- Counterbores and countersinks
- Threaded features
- Mounting surfaces
- Contoured profiles
- Datum surfaces
- Precision faces
- Complex prismatic geometries
Each project is evaluated according to the actual drawing, material, tolerance, quantity, inspection requirements, and required secondary processes.
Custom CNC Milled Parts
TDB Hanoi manufactures custom CNC milled components based on customer drawings.
Typical components may include:
- Housings
- Brackets
- Mounting plates
- Machine components
- Fixtures
- Precision blocks
- Mechanical components
- Equipment components
- Custom machined parts
Rather than offering standard catalog products, our manufacturing is primarily drawing-based and project-specific.
Materials for CNC Milling
We machine a range of metals and engineering plastics according to customer requirements.
Aluminum
Aluminum is commonly used for lightweight mechanical components, housings, brackets, plates, fixtures, and other precision parts.
Material grades such as AL6061 and AL7075 can be manufactured when specified by the customer.
Stainless Steel
Stainless steel is suitable for components requiring corrosion resistance, mechanical strength, and durability.
The exact stainless-steel grade should be defined on the drawing or RFQ.
Steel
Carbon and alloy steels can be machined for machine components, structural parts, fixtures, and other mechanical applications.
Material condition, heat treatment, and finishing requirements should be specified where applicable.
Brass & Copper
Brass and copper can be machined for custom mechanical, electrical, connector, fitting, and other precision components.
Engineering Plastics
TDB Hanoi also supports machining of selected engineering plastics according to customer drawings and material specifications.
For more information, see our CNC Machining Materials page.
Prototype, Low-Volume & Repeat Production
Different stages of product development require different manufacturing approaches.
TDB Hanoi supports:
Prototype → Low-Volume Production → Repeat Production
Prototype machining can help customers evaluate:
- Component geometry
- Assembly fit
- Functional requirements
- Manufacturing feasibility
- Inspection requirements
For approved components, the manufacturing process can then progress toward low-volume and repeat production.
Quality Control for CNC Milled Parts
Precision CNC milling requires more than accurate machining.
The manufacturing process must also verify that finished components meet the agreed drawing requirements.
Depending on the project, our quality process may include:
Incoming Verification → First-Part Inspection → In-Process Inspection → Final Inspection → Documentation → Shipment Release
Inspection can cover:
- Critical dimensions
- Hole sizes and positions
- Precision bores
- Flatness
- Parallelism
- Perpendicularity
- Profiles
- Datum-related dimensions
- Other drawing-defined characteristics
TDB Hanoi uses appropriate measuring equipment according to the feature and tolerance being inspected.
For components requiring more detailed dimensional verification, CMM and VMM inspection can be used where appropriate.
Engineering Review Before Production
Manufacturing quality begins before machining starts.
Our team reviews the project requirements, including:
- Drawing revision
- 2D and 3D data
- Material
- Critical dimensions
- Tolerances
- GD&T where applicable
- Surface finish
- Quantity
- Inspection requirements
- Secondary processes
- Packaging
- Delivery requirements
Where clarification is required, technical questions should be resolved before production.
This helps reduce manufacturing risk and avoids unnecessary rework.
Secondary Processes & Surface Finishing
CNC milling may be only one stage of the complete manufacturing process.
Depending on project requirements, additional processes can include:
- Deburring
- Grinding
- Heat treatment
- Anodizing
- Plating
- Painting
- Powder coating
- Other specified surface treatments
- Assembly
- Custom packaging
Secondary-process requirements should be defined during RFQ so that the complete manufacturing route can be evaluated.
Our CNC Milling Workflow
A typical CNC milling project follows:
1. Submit Drawings
Send your 2D/3D drawings and manufacturing requirements.
2. Engineering Review
We review material, geometry, tolerances, quantity, inspection requirements, and secondary processes.
3. Quotation & Production Planning
The manufacturing process and commercial requirements are evaluated.
4. CNC Milling
Components are machined according to the approved drawing and manufacturing plan.
5. Inspection
Required dimensions and critical characteristics are inspected throughout production.
6. Secondary Processes
Finishing and additional manufacturing processes are coordinated where required.
7. Final Inspection & Packaging
Finished components are verified, packaged, and prepared for delivery.
