Frequently asked questions

What specifications do you plate and spray to?

Hard chrome plating to AMS 2460 and AMS 2406; plasma spray to AMS 2437; magnetic particle inspection to ASTM 1444 and liquid penetrant to ASTM 1417 — each to the current revision. If your print calls out the cancelled AMS-QQ-C-320, tell us and we will work out the current equivalent with you.

How thick can you build up a worn part with hard chrome?

From .0001" for corrosion protection, where dimensional change must stay negligible, up to .050" to rebuild a worn component back to print — then ground to size in the same building.

How large a part can you machine?

CNC machining runs up to 27" in diameter, 100" long and 2000 lbs. Thermal sprayed parts run up to 6" × 120". Send a drawing if your component is outside that — the published envelope is a starting point, not a hard limit.

Do you grind after plating or spraying?

Yes. Precision grinding is in-house for both plated and sprayed components, so a rebuild comes to final size in the same building instead of shipping between vendors.

Are you approved for aerospace work?

Yes. BBC is an FAA approved Repair Station, #BK3R400L, working under FAR 145. The AMS and ASTM specifications we plate, spray and inspect to sit under that framework.

Are you ISO 9001 or AS9100 registered?

No. BBC holds an FAA Repair Station certificate under FAR 145 — an airworthiness approval, not a quality-system registration. They are different things, and we would rather say so plainly. If your programme requires AS9100 or ISO specifically, tell us early.

Can you inspect what you repair?

Yes — magnetic particle inspection to ASTM 1444 and liquid penetrant to ASTM 1417, in a complete inspection department on our own floor.

What do you need from me to quote a repair?

Ideally a drawing with the finished dimension, the specification called out, what the part does and how it failed, the substrate material and the quantity. None of it is mandatory — send what you have and we will ask about the rest. See our guide on how to specify a repair.

I do not have a drawing. Can you still help?

Yes. Send a photograph and the dimensions you can measure. Reverse engineering an obsolete component is ordinary work here — we have been repairing parts since 1945.

What are your lead times?

Lead time depends on the part, the processes involved and current shop load, so we quote it with the job rather than publishing a blanket figure. For an urgent repair, call the shop and ask.

How do I send a drawing or CAD file?

Use the quote form, which opens an email you can attach files to, or email info@bbcmachine.com directly. Please do not paste controlled or export-restricted data into the website chat.
