Automated CNC Turning Services in Vietnam

TDB Tech provides automated CNC turning services in Vietnam for shafts, bushings, sleeves, fittings, threaded parts and other rotational components. From two manufacturing facilities in Hanoi, our team supports drawing review, DFM, prototypes, repeat production, inspection and international delivery for US and EU buyers.

An NDA can be signed if needed before the quotation.

Why Choose Automated CNC Turning Services?

Automated CNC turning uses programmed machining cycles to produce rotational components with consistent process control across repeat orders. It is suitable for parts with diameters, bores, threads, grooves, tapers and shoulders, with secondary operations selected according to the drawing. TDB Tech reviews geometry, material, quantity and inspection requirements before recommending the production route.

Applications for Automated CNC Turning

Automated CNC turning is suited to rotational components that require stable, repeatable production across recurring orders. Process selection depends on part geometry, material, critical dimensions, thread requirements, batch size and inspection needs.

Hydraulic Components

Applications:

Typical parts include sleeves, bushings, threaded fittings, pins and other rotational components used in hydraulic assemblies. Final process and inspection requirements are confirmed from the customer drawing.

Key project requirements:

Vacuum System Components

Applications:

Automated turning can support shafts, connectors, sleeves and fittings used in vacuum equipment. Material, sealing features, surface finish and cleanliness requirements should be specified on the drawing.

Key project requirements:

Medical Equipment Components

Applications:

TDB Tech can review turned components for medical-equipment applications when the customer provides the applicable drawing, material, documentation and inspection requirements. Project feasibility is confirmed before quotation.

Key project requirements:

Industrial Machinery Components

Applications:

Applications include pins, spacers, shafts, couplings, bushings and threaded components for automation equipment, machinery and production systems.

Key project requirements:

Automated Turning for Complex and Repeat Parts

Automated CNC turning and Swiss-type machining are selected according to part length-to-diameter ratio, geometry, material, quantity and required secondary features. TDB Tech reviews each project before recommending the production route.

Drawing-Based Tolerance Review

Tolerance requirements should be defined on the latest 2D drawing. TDB Tech reviews critical dimensions, geometric controls, threads, material, fixturing and inspection method before confirming manufacturing feasibility and quotation.

Tolerance Type	Tolerance Confirmation	Application	Description
Dimensional Tolerance	Confirmed after drawing review	General parts with standard precision	Dimensional controls are defined on the latest drawing.
Geometric Tolerance	Confirmed after drawing review	Complex parts needing precise geometry	Form, orientation, location and runout controls are inspected as specified.
Straightness	Confirmed after drawing review	Components requiring straight edges	Straightness requirements are reviewed against part geometry and inspection method.
Flatness	Confirmed after drawing review	Parts needing a flat surface	Flatness requirements are reviewed against material, geometry and inspection method.
Cylindricity	Confirmed after drawing review	Cylindrical parts with strict tolerances	Cylindricity requirements are confirmed for the applicable turned features.
Concentricity	Confirmed after drawing review	Parts where concentricity is crucial	Concentricity requirements are reviewed with datum and inspection definitions.
Perpendicularity	Confirmed after drawing review	Parts needing precise perpendicular surfaces	Perpendicularity requirements are reviewed with datum and inspection definitions.

Automated CNC Turning FAQ

What information is needed for an automated CNC turning quotation?

Please send the latest 2D drawing and available 3D file, together with material, quantity, critical dimensions, thread specifications, surface finish, inspection requirements and delivery destination.

Is automated CNC turning suitable for prototypes and repeat batches?

Yes. The recommended process depends on part geometry, setup requirements, material and quantity. TDB Tech reviews both prototype and repeat-production requirements before quotation.

How does TDB Tech control critical dimensions on turned parts?

Critical dimensions are identified from the drawing and controlled through the agreed production and inspection plan. Datum definitions and inspection methods should be confirmed before production.

Which features can be produced with automated CNC turning?

Typical features include outside and inside diameters, bores, threads, grooves, tapers, shoulders and selected secondary features. Feasibility is confirmed from the drawing.

When is Swiss-type machining recommended instead of conventional turning?

Swiss-type machining is commonly considered for small-diameter, slender or complex turned parts that benefit from guide-bushing support. The final process is selected after engineering review.

Can TDB Tech support customer-specified finishing or coating?

TDB Tech can coordinate finishing or coating requirements when the specification, approved supplier requirements and acceptance criteria are provided. Feasibility is confirmed during quotation.
