Made-to-order CNC parts from your drawing — one-off prototypes through repeat production, in metal or engineering plastic.
Custom CNC machining means parts built from your drawing, not from a catalog — the geometry, the material, the tolerance, and the finish are all yours, and the program's job is to translate that into a part that comes off the machine to print. Quick Brown Fox Solutions manages custom CNC across the full range that matters to engineers and procurement teams: single-piece prototypes for fit-check and qualification, low-volume builds for first-article and pilot, and repeat production lots once the design is locked. The same ISO 9001:2015 quality management system in our manufacturing network controls all of it, so the prototype you approve runs the same way at production rate.
If you have a drawing ready and want to skip the reading, send it to request a quote. If you're newer to sourcing custom parts, our guide on how to get a custom part CNC machined walks the buyer process end to end.
Custom CNC work tends to move in stages: a first article to validate the geometry, a small pilot lot to validate fixturing and inspection, and then production at whatever cadence the program needs. Splitting those stages across shops adds cost — the production shop has to re-learn the part — and adds risk, because tolerances that worked in prototype are not guaranteed to repeat in someone else's fixture.
We manage both. Our prototype machining service handles first-article and low-volume builds with the same drawing-control and inspection discipline as production. Our production CNC machining service takes the proven setup and runs it at rate, with documented inspection records on every lot. The transition from one to the other doesn't restart the part; it carries forward.
Custom CNC machining is a category, not a process — the right platform depends on the part. Our production network runs four platform classes under one quality system.
CNC milling. 3-axis VMCs through full 5-axis machining, envelopes to X 32.5 inch / Y 20.5 inch / Z 20.1 inch on companion VMCs, with the 5-axis cell built around a 19-inch round trunnion, 18,000 RPM spindle, and 60-tool magazine. Right for prismatic parts, brackets, housings, manifolds, and contoured aerospace geometries.
CNC turning. Spindle bores from 1.625 inch to 3.05 inch, live tooling for cross drilling and milling, and high-precision platforms with plus/minus .0001 inch repeatability. Right for shafts, pins, fittings, and any cylindrical or symmetric part.
Swiss CNC. 5-, 7-, and 9-axis Swiss platforms with bar capacity from .812 inch to 1.50 inch, spindles to 8,000 RPM, and bar-fed production for high-volume precision turned parts.
Conventional support. Manual lathes, mills, drill presses, and saws back up the CNC cells in the network for stock prep, secondary operations, and one-off conventional work.
Custom CNC is by definition open-ended, but a working program sees the same families of parts come through often enough that we have dedicated pages for each. Browse the parts hub for the full set, or jump to the family that matches your drawing:
Custom shafts and pins — turned and Swiss-machined components for rotating assemblies, fastening, and locating. Custom fittings and connectors — threaded fittings, hose ends, connectors, and adapters for fluid and pressure systems. Custom brackets and housings — milled prismatic parts for structural mounting and enclosures. Valve bodies and manifolds — complex cavity work for fluid-handling assemblies. Sensor and instrument housings — tight-tolerance enclosures for instrumentation and pressure transducers. Mounting plates and faceplates — flat or contoured plates with hole patterns, finished faces, and edge detail.
Aluminum alloys, stainless steels, carbon and alloy steels, brass, bronze, copper, and engineering plastics run routinely through the network; titanium and high-nickel alloys are available on request. Material certs travel with the lot when the contract requires.
Engineering teams at prime contractors, federal agencies, instrumentation OEMs, and medical device manufacturers route custom CNC work through this service line. The tight-tolerance routine is what carries the regulated work; the same fixtures and programs carry the production scale-up.
Complex contoured geometries in a single setup.
High-volume precision turned parts to 1.50 inch bar.
Routine plus/minus .0002 inch with documented inspection.
