- Wall thickness
- Clamping forces
- Datum structures
- Cutting parameters
- Tool condition
- Thermal deformation
- Deburring
- Surface protection
- Final inspection
TDB manufactures custom aluminum components according to customer-supplied drawings and specifications.
Our engineering team reviews the part design, critical tolerances, material requirements, production volume and finishing expectations before confirming the manufacturing process.

OEM Product Components
TDB supports international OEM customers that require custom aluminum parts as part of a larger product or assembly.
We can manufacture individual components or coordinate additional manufacturing processes based on the approved project scope.
Aluminum Materials
The appropriate aluminum alloy depends on the component’s functional and commercial requirements.
When sending an RFQ, buyers should clearly specify:
- Aluminum alloy
- Material condition or temper
- Mechanical requirements
- Surface-treatment requirements
- Material certification requirements
- Approved material sources, when applicable
If an alloy has not yet been selected, TDB can review the manufacturing requirements with the customer. However, the final material decision remains subject to the product design and application requirements.
TDB does not substitute materials without the customer’s approval.
Aluminum CNC Machining Tolerances
TDB has dimensional machining capability down to:
±0.01 mm
This figure represents a machining capability, not a universal tolerance for every dimension on every component.
The achievable tolerance depends on:
- Part dimensions
- Component geometry
- Wall thickness
- Aluminum alloy
- Machining sequence
- Datum selection
- Fixture stability
- Surface treatment
- Measurement method
- Production quantity
TDB reviews critical dimensions during the quotation and engineering-review stages.
Dimensions requiring tight tolerances should be identified clearly on the technical drawing. Applying tight tolerances only where they are functionally necessary can help reduce machining time and production cost.
Surface Finishing for Aluminum CNC Parts
Aluminum components may require surface treatment for corrosion resistance, wear resistance, electrical performance or appearance.
Depending on the customer’s specification and the approved project scope, finishing processes may include:
- Anodizing
- Hard anodizing
- Chemical conversion coating
- Painting
- Powder coating
- Sandblasting
- Polishing
- Brushing
- Laser marking
Surface treatment can affect dimensions, threads, holes, sealing faces and assembly fits.
For this reason, finishing requirements should be included in the drawing and RFQ from the beginning of the project.
Where surface treatment is coordinated through an approved external partner, TDB remains responsible for managing the agreed manufacturing and inspection requirements within the confirmed project scope.
Quality Control for Aluminum CNC Milling
TDB operates under an ISO 9001:2015 quality-management system.
Our production-control process includes:
Incoming Quality Control
Incoming materials and purchased items are checked against the approved project requirements.
Material-documentation requirements should be agreed before an order is placed.
In-Process Quality Control
Critical dimensions and machining conditions are monitored during production.
In-process inspection helps identify potential deviations before the full production quantity is completed.

How to Reduce the Cost of Aluminum CNC Parts
International buyers can improve quotation accuracy and reduce unnecessary machining costs by following several practical principles.
Apply Tight Tolerances Only Where Necessary
Tighter tolerances normally require additional machining, inspection and process control.
Identify functional dimensions clearly rather than applying the same tight tolerance to the entire drawing.
Avoid Unnecessarily Deep Pockets
Deep pockets may require longer tools, multiple machining passes and reduced cutting speeds.
Where possible, adjust the design to improve tool access and machining stability.
Use Practical Internal Corner Radii
CNC milling tools create radiused internal corners.
Allowing a suitable internal radius can reduce machining time and tool wear.
Standardize Hole and Thread Sizes
Standard hole and thread sizes simplify tooling and inspection.
Nonstandard features may increase cost without improving product performance.
Provide Realistic Volume Information
Prototype, low-volume and repeat-production quantities require different machining and fixture strategies.
Providing an annual forecast helps the supplier evaluate the most appropriate production method.
Define Surface Treatment Early
Anodizing and other finishing processes may affect dimensions and appearance.
Early confirmation helps prevent redesign, rework and quotation changes.
Selecting an Aluminum CNC Milling Shop in Vietnam
When evaluating a CNC machining supplier, do not rely only on the lowest quoted unit price.
Ask the supplier to confirm:
- Whether machining is performed internally
- Available machine capacity
- Maximum workpiece dimensions
- Achievable tolerances
- Quality certification
- Inspection equipment
- Material traceability
- Surface-treatment control
- Export experience
- Packaging standards
- Production lead time
- Corrective-action procedures
A reliable supplier should explain its assumptions and identify technical risks before accepting the order.
