Nine vertical machining centers across our production network, 3-axis through full 5-axis, for prototype and production work.
CNC milling is the workhorse of our production network. From prismatic plates and pocketed housings to contoured aerospace brackets, the network's nine vertical machining centers cover the envelope, speed, and tooling diversity needed to turn a drawing into a finished part. Engineers and supply-chain buyers at prime contractors send work to Quick Brown Fox Solutions because the milling cell is sized for both small first articles and repeat production lots, with documented quality records under ISO 9001:2015 on every piece.
Each job is programmed against the customer drawing. We review the drawing for manufacturability, propose fixturing, and quote machine time against the actual cutter loads expected — not a generic shop rate. When a job moves from prototype to production, the same setup logic, tool list, and inspection plan carry forward. QBF carries UEI MA3DSJEPMFQ8 and CAGE 201W8.
The network's largest 3-axis VMC offers an X 32.5 inch / Y 20.5 inch / Z 20.1 inch envelope at 10,000 RPM with routine plus/minus .0002 inch tolerances. Multiple 3-axis VMCs at X 23 inch / Y 22 inch / Z 20 inch run at 12,000 RPM, again holding plus/minus .0002 inch. A second tier of 3-axis VMCs at X 22 inch / Y 16 inch / Z 18 inch and X 22 inch / Y 16 inch / Z 14 inch covers smaller prismatic work at 6,000 to 8,000 RPM, with a 20-tool ATC on one of the platforms keeping operator load light on multi-tool jobs.
For complex contoured geometries, the network's full 5-axis machining center adds a 19-inch round trunnion table, an 18,000 RPM spindle, and a 60-tool magazine, so multi-face parts come off complete in a single setup. Materials routinely run include aluminum alloys, stainless steels, carbon and alloy steels, brass, bronze, copper, and engineering plastics; titanium and high-nickel alloys are available on request. Secondary operations — surface grinding, bead and vapor blasting, mass-finish deburring, and stock preparation — are handled within the network.
Routine tolerances on CNC milled features ship at plus/minus .0002 inch, with the 5-axis cell consolidating multi-face geometry into a single setup to keep true position, concentricity, and perpendicularity inside print. Verification is performed on a benchtop optical comparator and with calibrated hand gauging, with in-process checks documented to the inspection plan. All work ships under the network's ISO 9001:2015 quality program with QBF's UEI MA3DSJEPMFQ8 and CAGE 201W8 on file.
