Answer to a Common Question
How Fast Can a CNC Shop Turn Around a Custom Part? (Realistic Answer)
"How fast can you turn this part?" is one of the two questions on every RFQ. Realistic answer depends on quantity, material availability, part complexity, and shop backlog. This guide sets honest expectations.
Turnaround by scope
| Scope | Realistic turnaround |
|---|---|
| Simple prototype in stocked material (existing customer) | Same-day to 3 days |
| Simple prototype in stocked material (new customer) | 3–7 days |
| Complex prototype requiring FAI | 1–3 weeks |
| Small production run in stocked material | 1–3 weeks |
| Medium production run | 3–5 weeks |
| Any part requiring mill-source material | 4–12 weeks (material dominates) |
| Emergency rig-down (existing customer, stocked alloy) | Same-day to next-day |
What can compress lead time
Existing customer relationship (setup + program already done). Stocked material. Simple geometry. Machine availability. Weekend/overtime work (expedite pricing typically applies).
What extends lead time
New customer (setup + qualification). Non-stocked material (mill lead time). Complex geometry requiring extensive programming. Documentation requirements beyond standard. High shop backlog.
Frequently asked questions
Where can I get expert answers on CNC turnaround?
Call B&R Productions in New Waverly, TX at (936) 291-7827 — we work on this class of problem weekly and are happy to talk. Alternatively, the r/Machinists subreddit, Practical Machinist forum, and specific alloy manufacturer's technical support can help with generic technical questions.
Can a CNC shop really turn around a part same-day?
Yes — for existing customers on stocked material, business-hours emergency work, and simple part geometry. Not for first-time customers on unusual alloys.
What's the fastest a Fadal VMC can produce a part?
Simple part in a stocked alloy: 4–8 hours setup + machining + inspection. Faster on a repeat setup.
