Does my part need 5-axis machining?	If your part has angled faces, multi-side features, complex surfaces or strict feature-to-feature relationships, 5-axis machining may reduce setups and improve accuracy.
Can you machine angled holes and surfaces?	Yes. Angled holes, tilted faces, compound angles and multi-surface features can be reviewed from your CAD model and 2D drawing.
Can you reduce setup error?	5-axis machining can reduce repeated re-clamping, helping maintain datum relationships, hole position accuracy and assembly interface consistency.
Can you inspect complex parts?	CMM inspection, datum checks, dimensional reports and first article inspection are available based on project requirements.
Do you support prototypes and low-volume orders?	Yes. 5-axis parts can be reviewed for prototypes, engineering samples, pilot builds and low-volume production.
Is NDA available?	Yes. NDA can be arranged before reviewing sensitive CAD files or technical drawings.

Machine Capability

5-Axis CNC Machining Capability

Before quoting, our engineers review the CAD model, datum structure, feature access, tolerance callouts, finishing requirements and inspection plan to decide whether 3+2, simultaneous 5-axis or another CNC process is the most practical approach.

Capability Area	Manufacturing Range	Best For
3+2 Axis Machining	The part is indexed to different angles while machining is performed in fixed positions.	Angled faces, side holes, multi-face parts, brackets, housings and better datum control.
Simultaneous 5-Axis Machining	The tool and workpiece move at the same time to machine complex surfaces and contours.	Curved surfaces, complex contours, medical-style fixtures, UAV parts and aerospace-style geometries.
Multi-Surface Machining	Multiple faces can be machined with fewer setups and reduced re-clamping.	Brackets, housings, robotic joints, structural components and complex fixtures.
Angled Hole & Feature Machining	Angled holes, tilted pockets, compound angles and non-orthogonal surfaces can be reviewed.	Parts where standard 3-axis milling would require multiple setups or special fixture planning.
Datum Relationship Control	Reducing re-clamping helps maintain feature-to-feature accuracy.	Critical hole positions, mating faces, assembly interfaces and precision mounting features.
Inspection Support	CMM inspection, first article inspection and dimensional reports available when required.	Complex parts with datum, true position, flatness, profile or assembly-interface requirements.

Process Fit

When to Choose 5-Axis CNC Machining

5-axis CNC machining is not required for every part. It is most valuable when your component has complex geometry, angled features, multiple machined faces or tight relationships between critical surfaces. By reducing repeated setups, 5-axis machining can improve consistency and reduce the risk of alignment error.

Simple plates, brackets and pockets may be more cost-effective with CNC milling service. Round components may be better suited for CNC turning service.

Choose 5-axis when

Parts include angled holes, tilted surfaces, compound angles, complex contours or strict datum relationships.

Consider 3-axis when

The part is mainly flat surfaces, standard pockets, simple holes or straightforward brackets.

Choose turning when

The part is mainly round, cylindrical, threaded or shaft-like.

Ask for DFM review when

You are unsure whether 3-axis, 3+2, simultaneous 5-axis or mill-turn machining is most efficient.

Strategy Selection

3+2 Axis vs Simultaneous 5-Axis Machining

Many 5-axis projects do not require full simultaneous machining. For many brackets, housings and multi-side parts, 3+2 machining can provide a practical balance of accuracy, setup reduction and cost control.

3+2 Axis Machining

The part is rotated and locked at an angle before machining. This is effective for angled faces, side holes, multi-face brackets and housings.

Simultaneous 5-Axis Machining

The tool and workpiece move together during cutting. This is useful for curved surfaces, complex contours and difficult tool access.

Design Tips for 5-Axis Machined Parts

For complex parts, machining success depends on clear datum strategy, realistic tolerances, tool access, fixture planning and inspection notes. Send both a 3D CAD model and 2D drawing when your part has critical features.

Clearly define datum surfaces and inspection references.
Specify angled hole depth, angle, tolerance and relationship to datums.
Avoid unnecessary deep narrow pockets when design allows.
Apply tight tolerances only to functional or assembly-critical features.
Mark CMM-required features clearly on the drawing.

For broader pricing factors, review CNC machining cost.

Your questions answered

5-Axis CNC Machining FAQs

When should I choose 5-axis CNC machining?

5-axis CNC machining is recommended when your part has angled faces, features on multiple sides, complex surfaces, strict datum relationships or machining areas that are difficult to reach with standard 3-axis milling.

What is the difference between 3+2 machining and simultaneous 5-axis machining?

In 3+2 machining, the part is positioned at an angle and then machined in a fixed position. In simultaneous 5-axis machining, the tool and part move at the same time, which is useful for complex contours and curved surfaces.

Can 5-axis machining reduce setup error?

Yes. By reducing repeated re-clamping, 5-axis machining can help maintain better relationships between features, datums and hole positions.

Can you machine angled holes and compound angles?

Yes. Angled holes, tilted surfaces and compound angle features can be reviewed from your CAD model and 2D drawing.

Can you inspect complex 5-axis parts?

Yes. CMM inspection, datum checks, dimensional reports and first article inspection are available based on project requirements.

Is 5-axis CNC machining always more expensive?

Not always. While machine time can be higher, 5-axis machining may reduce setups, improve accuracy and reduce secondary operations for complex parts. Our engineers review the CAD model to recommend the most practical approach.

What materials can you machine with 5-axis CNC?

Common materials include aluminum, stainless steel, titanium, brass, copper and engineering plastics such as PEEK, POM and nylon.

Do I need a 2D drawing for 5-axis parts?

A 3D CAD model is essential, and a 2D drawing is strongly recommended when your part has tight tolerances, datum requirements, threads, surface finish requirements or inspection notes.

Can you support prototype and low-volume 5-axis machining?

Yes. Baosheng supports 5-axis CNC machining for prototypes, engineering samples, pilot builds and low-volume production.

Can you sign an NDA before reviewing CAD files?

Yes. NDA can be arranged before file review when your project requires confidentiality.
