Single-setup complex geometry
Machine multiple faces, undercuts, and compound angles with fewer fixtures — reducing stack-up from re-clamping.
High-Precision Five-Axis CNC Machining — Complex Geometries in a Single Setup
Simultaneous five-axis milling for complex contours, undercuts, and multi-face features on suitable rigid metals and engineering plastics — fewer setups, tolerances confirmed via DFM before we cut.
Five-axis proof points
Tool access confirmed via DFM
We check wall thickness, undercuts, and spindle reach before locking axis strategy — thin walls and critical features stay intentional, not hopeful.
Critical features to ±0.005 mm
Typical five-axis production about ±0.01 mm on suitable rigid parts. ±0.005 mm on designated features where material and geometry allow — confirmed via DFM / per drawing.
What we provide
Simultaneous five-axis CNC milling for complex contours, thin walls, undercuts, and multi-face parts that would otherwise need many 3-axis setups. We program toolpaths for continuous access, lock fixture strategy in DFM, and pair Wire EDM or turning when the geometry cannot finish by five-axis milling alone. Secondary finishes and hardware assembly are available under the same project when needed.
Process flow
RFQ / CAD review
Upload STEP/IGES and 2D PDF for datums, undercuts, and critical feature callouts.
DFM
We check tool access, wall thickness, fixture strategy, and which tolerances justify five-axis versus 3/4-axis.
Material & process planning
Stock, workholding, and CAM strategy matched to grade and envelope (ref. up to about 800 × 600 × 500 mm).
Machining
Simultaneous five-axis toolpaths on rigid multi-axis centers with setup verification after fixture or tool changes.
Inspection
Dimensional verification per drawing — in-house CMM and shop metrology as required.
Shipping
Finishing and protected packaging when ordered as turnkey delivery.

CNC materials guide
Grade selection and machinability context.
Thin-wall and contour evidence
Continuous five-axis access keeps tool engagement stable on curved thin walls and compound surfaces — the same discipline we apply to undercuts and multi-face datums. Surface integrity and chatter control are planned in CAM and confirmed against the drawing before release.
Programming and multi-process delivery
Multi-plane CAM
Toolpaths planned across WCS planes so undercuts and hole patterns stay reachable without excess fixtures.
Ready-to-install modules
Hardware and bushings assembled into milled bodies when the PO calls for turnkey delivery.
Tolerance and quality
±0.005 mm applies only to designated critical five-axis features where material and geometry allow — always confirmed via DFM and per drawing. Typical five-axis delivery around ±0.01 mm is likewise conditional. In-house pre-shipment inspection follows the agreed plan; optional FAI and material documentation (MTR) are available on request. Details: CNC machining quality control.
Applications
Aerospace-style structures
Brackets and multi-face parts where geometric control and fewer setups matter — industry relevance only, not a certification claim.
Robotics and automation
Joint housings, links, and interface geometry that benefit from continuous five-axis access.
Industrial equipment
Complex housings and tooling components that would otherwise need many 3-axis setups.
Five-axis FAQ
When do I need five-axis instead of 3-axis milling?
Choose five-axis when undercuts, compound angles, or single-setup multi-face accuracy reduce fixtures and stack-up. Prismatic parts with simple access are often more economical on 3- or 4-axis — we confirm during DFM.
Can every part hold ±0.005 mm?
No. ±0.005 mm is a critical-feature capability on suitable rigid parts where the drawing specifies it and DFM confirms material and geometry. It is not a default for all dimensions.
Do you provide finishing and assembly?
Yes when ordered as turnkey: common finishes (anodize, passivation, plating, bead blast) and basic hardware integration. Scope is confirmed at quote.
