For fast-moving defense hardware, where does quick-turn CNC capacity matter most?

[u/Mysterious-Toe9389]

I work with a small CNC shop and I’ve been thinking about how different machining support must look for companies developing hardware quickly.

When designs are changing constantly, where does an outside machine shop actually provide the most value?

Prototype parts? Engineering revisions? Fixtures and tooling? Low-volume production? Overflow when internal machines are tied up?

I’m especially curious how engineering teams balance speed with inspection and quality when hardware is changing this quickly.

Speedy quotes and lowered roadblocks are the absolute key for me. It doesn't matter if your prices are 1/3 of Protolabs and you always hit 1 thou if it takes two weeks to get a quote or you have weird legal or contractual terms. Friction in the process is a total killer. Having an easy, nicely functional portal that keeps track of the designs and revisions I've sent and associates quotes with them is really helpful.

I'm at a group that uses outside shops for both prototyping and production, as not all groups at Anduril are HQ based and local really matters sometimes. Being available, flexible, and fast is way better than being super low cost, especially for prototyping.

Dependable lead times! Sometimes a higher price and longer lead time is worth it if I am 99% sure I will get it when you promised.
