CNC Milling & 5-Axis Machining
From simple brackets to impellers with free-form blades: complex parts machined in fewer setups for better accuracy.
3- and 4-axis CNC milling
The workhorse for most machined parts: housings, plates, brackets, manifolds and fixtures. A 4th axis lets us machine features on several sides without re-clamping.
Typical parts: enclosures, mounting plates, heat sinks, fixtures, valve bodies.
5-axis CNC machining
5-axis machining tilts and rotates the part so the cutter reaches almost any surface in one setup.
Our 5-axis machines use a trunnion table, so a valve block or manifold can be machined on five faces in one clamping.
Typical parts: valve blocks and manifolds, impellers, aerospace brackets, medical device prototypes, robotic joints, mold inserts.
- Better accuracy between featuresNo error added by re-clamping.
- Complex geometryImpellers, blades, undercuts and compound angles.
- Better surface finishThe tool stays at the optimal angle.
- Shorter lead timesFewer setups and fixtures.

Design tips for lower-cost milled parts
Radius internal corners
Use internal corner radii slightly larger than the cutter, e.g. R3 instead of sharp corners.
Keep pockets shallow
Keep pocket depth under about 4× the cutter diameter.
Tolerance only what matters
Specify tight tolerances only on functional features.
Use standard sizes
Standard hole and thread sizes reduce tooling cost.
