Tight-Tolerance 5-Axis CNC Machining
With 10 years of precision machining experience, Big Sky Manufacturing builds tight-tolerance components across aerospace and other precision-driven industries — from first article to production runs, cut to spec, every time.
Machining built around tolerance, not around convenience.
Simultaneous 5-axis machining lets us hold tight tolerances on complex, multi-face geometry in a single setup — reducing fixturing error and keeping critical features in true relation to one another.
Simultaneous 5-Axis
Complex contoured and multi-plane parts machined complete, in fewer setups, with tighter part-to-part consistency.
Tight-Tolerance Precision
Work holding, tooling, and inspection are all built around holding aerospace-grade tolerances, not just meeting them.
Prototype to Production
From single first-article parts to repeat production runs, we scale the process without re-proving your part.
Precision Program Support
Built to work within demanding supply chains — documentation, traceability, and consistency, part after part.
Exotic & Hard Alloys
Titanium and Inconel are cut daily here, not treated as a special case — process and tooling are already proven.
ITAR-Controlled Work
Registered to accept ITAR-controlled parts and data, with the handling discipline that requires.
Almost anything you can spec, we can cut.
Our tooling, feeds, and speeds are dialed in across the alloys aerospace actually uses — from soft aluminum to work-hardening Inconel.
A decade of tight-tolerance precision.
For 10 years, Big Sky Manufacturing has built tight-tolerance parts across aerospace and other precision-driven industries. As an ITAR-registered shop, we're equipped to handle export-controlled parts, drawings, and data with the process discipline that requires.
Registered for Export-Controlled Work
If your program requires ITAR handling for hardware, drawings, or technical data, we're already set up for it — so onboarding your part doesn't mean building a process from scratch.
Big Sky Manufacturing
Based in Gilbert, Arizona, Big Sky Manufacturing is a precision CNC machine shop built around simultaneous 5-axis machining and tight-tolerance work. With 10 years of precision machining experience, we work across aerospace and other precision-driven industries, machining the full range of materials those programs call for — aluminum, stainless steel, steel, titanium, Inconel, plastic, copper, and bronze — and we're ITAR registered to support export-controlled programs.
Under big sky or big city, the standard is the same: hold the tolerance, hit the spec, every part.
