CNC machining lead time is typically one to three weeks for simple prototypes and three to six weeks for production lots, measured from order to shipment. Material availability, outside finishing, and inspection requirements are the factors that most often extend those ranges.
The machine time for a part is usually minutes or hours. How long CNC machining takes from a buyer's point of view depends on everything around that machine time: quoting, material, scheduling, programming, finishing, and inspection. This page breaks down each step so you can plan realistically.
How long does CNC machining take? Typical lead-time ranges
| Order type | Typical lead time | Main variables |
|---|---|---|
| Simple prototype, stock material, no finish | 1-2 weeks | Programming time, schedule |
| Prototype with anodize, plating, or heat treat | 2-3 weeks | Outside processor turnaround |
| Production lot, common material | 3-6 weeks | Machine capacity, lot size |
| Production lot with FAI and full CMM reports | 4-7 weeks | Inspection time, approval cycle |
| Special alloys (Inconel, Hastelloy, some titanium) | Add 1-6 weeks | Mill or distributor lead time |
| Repeat order, proven program | Often shorter than first run | Material and schedule only |
These are typical industry ranges, not commitments. Your quote will state the lead time for your specific part and quantity.
The steps inside a machining lead time
Quoting and order entry
A complete RFQ package is usually quoted within a few business days. Missing information adds time before the clock on production even starts.
Material
Common aluminum, steel, stainless, and brass bar and plate are generally available from distributors within days. Nickel alloys, titanium in specific grades and sizes, and material requiring DFARS-compliant sourcing can take longer. See our materials page for the alloys we machine.
Programming and setup
New parts need CAM programming, tooling selection, and fixturing. Repeat parts skip most of this because the program and setup notes are saved.
Machining
Actual run time depends on cycle time and lot size. Horizontal machining centers with pallet changers let the next part be loaded while one is cutting, and Swiss machines with bar feeders can run unattended. Wexmar operates a second shift and can run Swiss lights-out, which adds capacity without adding calendar days.
Outside processing
Heat treat, plating, anodizing, passivation, and black oxide are performed through qualified outside processors. Typical processor turnaround is several business days to two weeks, plus transit. Parts that need heat treat before finish machining add a round trip.
Inspection and shipping
Final inspection, CMM reports, and AS9102 first article documentation are completed before shipment. Our inspection and quality page describes this step. Parts then ship by parcel or LTL from Canastota, New York.
Machine time versus lead time
It is common for a buyer to see a cycle time of twelve minutes and expect parts in a day. Lead time is longer because the part waits in several queues: for material to arrive, for an open machine, for an outside processor, and for inspection. A shop quoting a realistic date is accounting for each of those queues. A shop quoting a date that ignores them may miss it. When you compare quotes, compare the stated lead times and ask what each one includes, especially whether finishing and inspection documentation are inside the date.
Government and defense orders
Orders that require DFARS-compliant specialty metals, first article approval, or source inspection usually take longer than commercial work. Build that time into your requirement date. Wexmar invoices through WAWF/PIEE and can provide material certs and AS9102 first article reports with shipment.
What makes CNC machining take longer
- Drawing questions that are not answered quickly
- Special material grades or certification requirements
- Multiple outside processes in sequence
- Tight tolerances that require extra setups or grinding
- First article approval required before the lot can proceed
How to shorten lead time
- Send a complete package: PDF drawing, STEP model, material, quantity, and finish
- Name a technical contact who can answer questions the same day
- Approve alternate materials in advance if the specified grade is scarce
- Split the order so a few parts ship early for fit checks
- Place repeat orders against a proven revision
Rush orders
When a date is fixed, tell the shop at the RFQ stage. A shop can often reorder its schedule, use a second shift, or expedite an outside processor if it knows early. Expediting usually costs more, and it cannot shorten a material mill lead time.
