Machining
BB Airparts delivers aircraft‑ready assemblies under one roof, reducing vendors, rework, and risk while keeping parts complete, correct, and on time. .
What size range of parts can you support with your 3‑, 4‑, and 5‑axis mills?
Our range spans from very small details on compact 5-axis trunnion machines up to large structural parts measuring 2.5 ft × 4.5 ft × 13 ft on our Makino MAG3 EX large-format gantry.
Which CNC brands and models do you run for milling aerospace components?
We run a deep Haas fleet across 3-, 4-, and 5-axis platforms (VF-2, VF-9, GR-512, UMC 750SS, UMC 1000SS, UMC 1250SS, and more), six Modig HHV-3 horizontal machines, and two Makino MAG3 EX next-generation large-format 5-axis machining centers.
Can you hold the tight tolerances required for structural aerospace parts?
Yes. Our equipment, processes, and AS9100D certified quality system are built for aerospace tolerances. Partners like Hartwig have noted that we are "fast and can hold tight tolerances.
How quickly can you quote and turn typical CNC milling work?
We pride ourselves on rapid quoting. All decisions are made internally — no corporate red tape — so you typically hear back fast. We simply ask for the opportunity to quote and believe you'll be pleasantly surprised.
What materials do you commonly machine, especially in aluminum and aerospace alloys?
We primarily machine aluminum in 6061, 7075, 2024, and 6063 alloys. We also work with stainless steel, 4130/4340 and precipitation-hardened steels, titanium Ti-6Al-4V, and select composites.
Assembly
With one of Wichita’s deepest CNC fleets, BB Airparts mills everything from simple brackets to complex 5‑axis structures with high quality, low cost performance. .
What types of aerospace assemblies can you deliver complete to the aircraft line?
We deliver fully integrated major assemblies including cockpit instrument panels, machined pressure bulkhead assemblies, structural sub-assemblies, and bracket/clip/angle packages — all built to print and ready for aircraft installation.
Can you integrate both machined and sheet metal parts into one major assembly?
Yes. Because we perform CNC machining, sheet metal fabrication, forming, and assembly all under one roof, we integrate machined details, formed sheet metal components, and purchased hardware into a single, complete deliverable.
How do you ensure assemblies are delivered complete, correct, and on time?
Our AS9100D / ISO 9001 certified quality system governs every step of production. Because all work is done in-house, we control the full schedule with no external dependencies — and our team motto is simple: complete, correct, and on time.
Can you build cockpit panels or pressure bulkhead assemblies to our print?
Absolutely. We have built cockpit instrument panels with up to 180 individual detail components and machined pressure bulkhead assemblies. If you have a print, we can build to it.
Do you provide first article inspection reports (FAIR) for complex assemblies?
Yes. Our quality team supports FAIR and PPAP documentation as required by your program. All work is traceable through our AS9100D certified quality management system.
Forming
With one of Wichita’s deepest CNC fleets, BB Airparts mills everything from simple brackets to complex 5‑axis structures with high quality, low cost performance. .
What sheet metal forming processes do you offer in-house?
We offer hydroforming (Williams White 200-TON and Tippo 750-TON), CNC press brake forming (AccurPress 60-TON and Di-Acro), water jet cutting (2× Flow 3-axis), and CNC high-speed routing (4× MultiCam) — all in-house.
What gauges and sheet sizes can you form for aerospace applications?
Our hydroforming presses handle bed sizes from 24×54 up to 22×76 inches, and our press brakes form up to a 96-inch bed. We work across a broad range of gauges from thin sheet through heavy-gage structural stock.
Do you work from customer-supplied tooling, or can you design form tools for us?
Both. We can accept customer-supplied tooling or work with our engineering team to develop and design form tools for your specific part geometry as part of our DFM support.
How do you inspect formed parts to ensure they meet contour and tolerance requirements?
All formed parts are inspected through our AS9100D quality system. Inspections are performed against customer drawings and any applicable first article or FAIR requirements.
Can you supply formed parts ready for paint, bonding, or further assembly operations?
Yes. Parts leave our facility clean and ready for the next step — whether that is painting, bonding, anodize, or direct integration into a higher assembly. If that assembly step is also needed, we can do it in-house.
