How to prepare a CNC machine RFQ: 8 things to include
A complete request for quotation lets suppliers recommend the right machine, configuration and cycle time the first time, instead of weeks of back-and-forth. Asking only “how much is a CNC lathe?” usually brings back quotes you cannot compare. These are the 8 things to prepare before you ask for a price.
1. Part drawing and critical tolerances
Send the 2D drawing (PDF or DWG) and a 3D model (STEP) if you have one. Mark the most important dimensions, tolerances, surface finish and geometric tolerances, such as concentricity or perpendicularity. If the drawing is confidential, hide logos and part numbers, or send only the envelope size and key tolerances.
Why it matters: size and tolerances decide the travel, maximum turning diameter, rigidity and accuracy the machine needs.
2. Material and stock form
State the material grade (for example 1045, 304 stainless, 6061 aluminum), the hardness after heat treatment, and the stock form: bar, forging, casting or tube, with its size. If your drawing uses a grade from another standard, look it up in the steel grade equivalents chart.
Why it matters: the material sets spindle power and tooling; bar stock sets the spindle bore and whether you need a bar feeder.
3. Annual volume and batch size
How many parts per year, how many per batch, and how often you change over to another part.
Why it matters: low volume and high mix call for a flexible machine with quick changeover; high volume calls for automation and a machine that combines operations.
4. Target cycle time
Your target in seconds or minutes per part, or the current time if you already make it.
Why it matters: it decides how many machines you need, and whether one turn-mill center or several simpler machines is the better choice.
5. Current process and problems
Which machines you use now, how many setups, and which operations (turning, milling, drilling, tapping). What is going wrong: unstable accuracy, long cycle times, scrap, or a shortage of operators.
Why it matters: fewer setups and combined operations are usually where a new machine pays off most.
6. Automation and shifts
Do you need a bar feeder, robot loading, a parts catcher or in-machine measuring? How many shifts do you run, and do you want to run lightly staffed at night?
Why it matters: automation has a large effect on configuration and price, so decide it at the start rather than upgrading later.
7. Budget and timing
Give a budget range and when the machine must be in production. A new machine usually takes about 1.5–5 months to build, depending on model and configuration, plus shipping, customs clearance and installation; sea freight from Taiwan or China to Vietnam takes about 5–7 days.
Why it matters: the supplier can propose the right route: a new machine, a stock machine, or an inspected used machine.
8. Factory conditions
Factory location, power supply (factories in Vietnam typically run on 3-phase 380 V, 50 Hz) and spare capacity, compressed air, floor space and door size, and whether a crane or forklift is available for unloading.
Why it matters: it avoids extra cost and delays at delivery and installation.
3 common mistakes
- Asking for a price without part information: each supplier guesses the configuration, and the quotes cannot be compared.
- Comparing prices, not configurations: the control, turret, accessories, warranty and training can differ a lot.
- Forgetting the extra costs: fixtures, tooling, import duty, VAT and installation. Estimate them with the import cost calculator.
What you get back
With these 8 items you receive a recommended machine type and configuration, an estimated cycle time, a quotation and a delivery time. Subject to conditions, a trial machining run with your own part can be arranged; we agree the details per project.
