5-Axis CNC Machining Services for Complex Parts

Two rotary axes added to standard X/Y/Z travel let a tool reach five sides of a part in one setup. That is the core of 5 axis machining: fewer re-fixturing steps and tighter control of compound angles than standard CNC machining services.

DEK runs this capability at prototype quantities and above, with no minimum order, for aerospace (non-flight-critical), medical, robotics and semiconductor OEMs. Profile tolerances hold down to ±0.01mm on titanium and Inconel 718, and compound-curved brackets and housings run on our complex parts CNC machining line.

Why Choose DEK for 5-Axis Machining Services

Track record, documented tolerances and audited certifications: three things to check before sending a drawing to any 5-axis shop.

  • Track Record at Scale

    1.2M+ parts produced annually for 2,300+ global OEM clients over 20+ years of 5-axis work, not a handful of case studies.

  • On-Time Delivery

    A 98.6%+ on-time delivery rate, so complex 5-axis parts arrive when your prototype build or production schedule needs them.

  • Documented Tolerances

    Tolerances quoted in millimeters against defined part categories, from ±0.003mm micro parts to ±0.01mm compound profiles, not one blanket number.

  • Third-Party Certified

    ISO 9001, ISO 13485 and AS9100D issued via TUV, not self-declared: AS9100D for aerospace-adjacent parts, ISO 13485 for medical devices.

No MOQ, Prototype to Production

With no minimum order quantity, the AS9100D-certified 5-axis process is available on a single prototype. Every quote starts with a DFM review of feature access, fixturing and tolerance stack-up.

  • Simultaneous 5-Axis vs 3+2 Positioning

    DEK chooses between simultaneous and positional cutting based on part geometry and finish requirement, not a default machine setting.

    • Simultaneous: all five axes move during the cut
    • Smooth toolpaths for free-form surfaces
    • 3+2: rotary axes locked at a fixed angle
    • 3+2 is faster and lower cost on angled faces

    Parameter Specification
    Simultaneous 5-axis All five axes move in the cut
    Simultaneous best for Impeller blades, turbine housings
    3+2 positioning Rotary axes locked per operation
    3+2 best for Several angled faces
    3+2 relative cost Faster, lower cost
    Selection basis Part geometry and finish

  • 5-Axis Machining Tolerances

    Tolerances are documented per capability tier, so each feature is quoted against what the process actually holds.

    • ±0.01mm profile control on compound curves
    • ±0.005mm on shaft-bore and coaxial fits
    • ±0.003mm on sub-10mm micro components

5-Axis vs. Other CNC Machining Options

Not every part needs 5-axis: flat-faced parts are often faster and cheaper on 3-axis, and a few angled features may only need 3+2 positioning. Read how 5-axis works.

Criteria This ProcessSimultaneous 5-Axis 3-Axis CNC 3+2 Positioning
Best for Free-form, compound curves Simple, flat-faced parts Several angled faces
Toolpath All five axes move together X/Y/Z only Rotary locked, 3-axis cut
Complex part setups Single setup Several setups One angle per operation
Speed Fastest on complex geometry Quicker on simple parts Faster than simultaneous
Choose when Impellers, turbine housings No angled features Two or three angled features

Complex Geometries We Machine in 5-Axis

Compound curves, undercuts and multi-angle faces are where single-setup machining outperforms 3-axis setups.

  • Compound Curves & Impellers

    Simultaneous toolpaths produce the smooth, continuous surfaces that impeller blades and turbine housings need.

  • Undercut Geometries

    Compound-curved undercuts are reached in one setup where 3-axis needs several; see our undercut machining guide.

  • Multi-Angle Brackets

    Brackets with compound-angled mounting faces, machined in one setup to reduce assembly variation.

  • Housings & Manifolds

    Joint housings, manifolds and chamber components with multiple angled mounting faces.

  • Large Structural Parts

    Parts up to roughly 1000mm follow the same machining and inspection process; see large part CNC machining.

  • Small Feature-Dense Parts

    Sub-10mm connectors and small sensor housings held to ±0.003mm with micro machining.

Design Limits We Flag in DFM

  • Tool-Access Angles

    A feature that looks fine in CAD can still force an extra setup, so tool access and fixturing are checked before the quote is issued.

  • Minimum Internal Radii

    Tight internal radii can force a smaller cutter than planned; fillet radius and internal-corner access are reviewed on your drawing.

  • Thin Walls Near Undercuts

    Wall thickness around undercuts is one of the usual DFM flags, because it drives machinability long before production starts.

  • Fit-Critical Features

    Flag tight tolerances and fit-critical features up front to avoid a re-quote after DFM review; shaft-bore fits hold ±0.005mm.

5-Axis Machining FAQs

Cost, design limits and speed: what engineers ask before sending a 5-axis part.

How much does a 5-axis CNC cost?
Cost depends on part geometry, material, tolerance requirements and quantity. A titanium bracket held to ±0.01mm profile control costs more than a simple aluminum part, so submit a CAD file for an accurate quote rather than estimating from a per-hour rate.
What design limits should I watch for when submitting a part for 5-axis DFM review?
Tool-access angles, minimum internal radii and wall thickness around undercuts are the usual flags. A feature that looks fine in CAD can still force an extra setup or a smaller cutter; flagging tight tolerances or fit-critical features up front avoids a re-quote.
Is 5-axis CNC machining faster?
Often, on complex geometry: single-setup machining removes re-fixturing steps and tool changes between operations. For simple flat-faced parts, 3-axis machining can still be quicker and cheaper; 5-axis earns its speed advantage on complexity, not on every job.
