The short answer
CNC turned parts lead time is made up of several stages: quotation, material, setup and first article, production, outside finishing and shipping. Some overlap, and many quotes give only the production days. So how long does CNC turning take? Before you compare two lead times, ask three things: what day the clock starts, which stages are inside the quoted days, and whether shipping is included.
A note on who wrote this: we are a CNC turning factory in Dongguan, China. Our typical production lead time is 15–20 days, counted from the day after the purchase order. Each section gives the general picture first, then our own numbers. Jump to our lead time, stage by stage Other ordering questions
Where CNC turned parts lead time goes
The stages do not simply add up. Material is often bought while the program is written, and one supplier may count outside finishing inside its production days while another adds it on top. Ask for each stage that matters to your part, and for the date on the quotation.
How we answer: a formal quotation takes 1 working day from a complete PDF drawing and the quantity. Common materials arrive in 1–3 days and special grades in 5–10 days, so name the exact grade on the drawing. Production takes 15–20 days. Two real orders: 5,000 anodized sleeves in 20 days, counted from order receipt and including anodizing trials with three finishing suppliers, and 10,000 brass brackets in 30 days for a larger batch.
First order or repeat order
A first order carries one-time work: programming, fixtures and a first-article check of every dimension. A repeat order of the same drawing revision reuses the program and fixtures, so it should be faster. If you need to sign off sample parts before the batch, agree whether the waiting time sits inside the lead time or outside it. How to plan the first batch and repeat orders
How we answer: a repeat order is about 2 days faster than the first, depending on quantity and how difficult the part is. When you need to approve the first article, you place a first-article approval order for sample parts first. After approval you place the production order, and the 15–20 days start from the day after that order.
Outside finishing adds days
Anodizing and plating are usually done by a specialist finishing supplier, and so is some heat treatment. The parts leave the turning shop, join that supplier’s schedule and are inspected when they come back. Ask how many days each process adds and what is checked on return.
How we answer: anodizing and plating add about 2 days, and heat treatment we send out about 4 days, from leaving our factory to coming back. We harden C45 and 4140 in-house. Returning anodized parts are checked for appearance, dimensions and coating thickness; heat-treated parts for hardness, distortion and surface cracks or scale.
What makes lead time longer, and what you can do
Five things add days, and a buyer can plan for each. A drawing change after the order resets programming and sometimes material. Open questions on the drawing hold the job until they are answered. A special material grade adds buying time. A finishing reject sends parts back for rework. A first article that fails means correcting the setup and checking again.
How to plan for it: send the current drawing revision and answer drawing questions before the order. Name the exact material grade at quotation, so special stock is ordered on day one. Give the finished dimensions and finish specification, so first articles pass the first time. If a date changes on our side, we tell you directly by email and WhatsApp.
Shipping to Europe and the US
Sea freight can take longer than production, so check whether the quote includes transit. Check the Incoterm too: on EXW and FOB quotes you arrange the main freight and import clearance; on DDP the supplier delivers duties paid. How to compare quotes on the same basis
How we answer: to Europe and the US, express takes 3–7 days, air freight about 10 days and sea freight 30–40 days. Our DDP quotations state the transit time separately from the production lead time.
When you need parts sooner
A supplier can shorten lead time in only a few ways: add people and machine hours, split the batch, or ship from stock already made. Each costs something. Agree the date and any rush charge in writing before the order. For large batches, ask for a delivery schedule rather than one date.
How we answer: we take rush orders from existing and large customers. A rush order means adding staff, so it carries a rush fee that depends on how many days are cut. At the fastest, 2,000 pcs can ship within 7 days. If you buy the same part regularly, we can make the batch in one run, keep it at our factory and ship releases as you call them off.
