5-Axis CNC
Machining Service

5-axis CNC machining is a manufacturing process where a cutting tool moves simultaneously across five axes — X, Y, Z (linear) plus A and B (rotary) — allowing the workpiece to be approached from virtually any angle. This enables complex geometries, undercuts, curved surfaces, and multi-face features to be machined in fewer setups with greater accuracy compared to standard 3-axis milling.

In 3+2 (positional) machining, the two rotary axes position the workpiece at a fixed angle, then conventional 3-axis machining is performed. This is ideal for angled holes, multi-sided parts, and indexed features. Simultaneous 5-axis machining moves all five axes at the same time, enabling the machining of continuous free-form surfaces, impellers, turbine blades, and complex organic contours that cannot be achieved with 3+2.

Choose 5-axis machining when your part has: multiple angled faces, complex curved or free-form surfaces, deep cavities or undercuts that are inaccessible with a vertical 3-axis setup, critical positional relationships between features on different faces, or when repeated manual re-clamping would introduce unacceptable error accumulation. If your part requires more than 2 setups on a 3-axis machine, 5-axis is likely more cost-effective.

Parts best suited for 5-axis machining include: impellers and turbine blades, aerospace structural brackets and connectors, medical device components and surgical instrument parts, precision molds and die inserts, multi-face housings and enclosures, complex hydraulic manifolds, robot joint housings, UAV structural frames, deep cavity aluminum parts, and any part with compound angles or undercuts.

Yes. 5-axis machining improves accuracy in two ways: first, by reducing the number of setups, it eliminates re-clamping errors that accumulate each time a part is repositioned. Second, it allows shorter, more rigid tooling to reach complex features, reducing tool deflection and vibration — both of which are major contributors to dimensional error on 3-axis machines.

Yes, significantly. A part that requires 4–6 setups on a 3-axis machine can often be completed in 1–2 setups on a 5-axis center. Each eliminated setup removes a potential source of positioning error and reduces cycle time, clamping labor, and the risk of part damage during handling.

Our 5-axis machining centers process aluminum alloys (6061, 7075, 2024), stainless steel (304, 316L, 17-4PH), carbon and alloy steel (1018, 4140, 4340), titanium (Grade 2 and Grade 5/TC4), nickel superalloys (Inconel 625, 718), and engineering plastics (PEEK, Delrin/POM, PTFE). Material selection is driven by the application — we can advise on optimal material choice during the DFM review.

Yes. We support 5-axis machining from single-piece prototypes through to full production. Prototypes typically ship in 3–5 business days. There is no minimum order quantity. A DFM review is included with every prototype order to identify any features that may need adjustment for 5-axis manufacturability.
