Complex contoured geometries machined complete in a single setup — no re-fixturing, no stack-up.
5-axis CNC machining reaches every face of a contoured part in one fixture, eliminating the tolerance stack-up and rework that comes with multiple setups on 3-axis equipment. For aerospace housings, impellers, turbine components, medical instrument bodies, and any geometry with compound angles or undercuts, this is the fastest path from drawing to first article. Our production network includes a full 5-axis machining center built around a 19-inch round trunnion table, an 18,000 RPM spindle, and a 60-tool magazine — the same combination of envelope, surface speed, and tool capacity that prime contractors specify when they cannot afford a second op.
Every 5-axis job is programmed against the customer drawing before the spindle ever turns. The drawing, GD&T callouts, datum schemes, and special process notes are evaluated against the network's ISO 9001:2015 quality system, and we flag anything that needs clarification before quoting.
The 5-axis cell in the network is built around a full simultaneous-motion machining center with a 19-inch round trunnion that handles A and C axis rotation. The 18,000 RPM spindle is ideal for small-diameter cutters in aluminum, titanium, and stainless, where high surface speed is the only way to hold finish and tool life on tight inside radii. A 60-tool magazine keeps complete cutting libraries resident for long-cycle parts — rougher, finisher, ball mills, drills, taps, chamfer tools, and probing — without operator intervention.
For larger 3-axis prismatic work that does not require simultaneous motion, the envelope extends to X 32.5 inch / Y 20.5 inch / Z 20.1 inch on companion VMCs in the network, with spindle speeds to 12,000 RPM and routine tolerances of plus/minus .0002 inch. Workholding ranges from precision vises and tombstones to dedicated soft jaws and custom fixtures for repeat production. Materials in routine production include aluminum alloys, stainless steels, carbon and alloy steels, brass, bronze, copper, and engineering plastics; titanium and high-nickel alloys are available on request.
5-axis work ships with routine tolerances of plus/minus .0002 inch on linear features, with concentricity and true-position tolerances controlled through single-setup machining rather than multi-op stack-up. First-article and in-process verification is performed on a benchtop optical comparator and with calibrated hand gauging, and every part ships against a documented inspection record under the network's ISO 9001:2015 program.
