Overview
What Is Small Batch CNC Machining?
Small batch CNC machining, also called low volume CNC machining, is the production of a small number of precision parts using computer-controlled milling and turning machines, without a mandatory minimum order quantity. Each part is machined directly from solid metal or engineering plastic, producing finished components that are dimensionally accurate and ready for use without the cost or delay of dedicated tooling. Smell batches are usually required for prototypes, small series or pre-series and spare parts.
Compared with post-molding assembly, insert molding offers several important advantages:
How it works:
STEP, IGES, DXF, DWG or PDF drawings accepted. Sketches or dimensions work too for simple parts.
Itemised price covering unit cost, material, surface finish, and confirmed lead time.
Engineers review your design for manufacturability, then machining starts immediately after your sign-off.
Every batch is dimensionally inspected before packing. Ships worldwide door-to-door with a quality report.
Comparison
Small Batch vs Large Volume
The machining process is identical at any volume. What changes is how setup cost is spread across fewer parts. For most small batch orders there is no additional tooling cost. Standard end mills cover the majority of geometries.
| Factor | Small Batch (1–200 pcs) | Large Volume (500+ pcs) |
|---|---|---|
| Unit price | Higher per piece | Lower per piece |
| Tooling cost | Usually none | May apply for custom fixtures |
| Lead time | 5–10 days | 10–25 days |
| Design changes | Easy — no tooling to remake | Costly if tooling is involved |
| Inventory risk | Minimal | Higher |
| Best for | Prototypes, pilots, R&D, spare parts | Mature, stable designs at scale |
MOQ for CNC machining: 1 piece
Davantech has no minimum order quantity for CNC machined parts. You can order one prototype, ten samples or a few thousand series parts from the same factory, on the same machines and with the same inspection. What changes with quantity is not whether we accept the order, but how the fixed setup cost is spread over the parts.
| Quantity | What drives the price per piece | Typical use |
|---|---|---|
| 1 piece | The full setup (programming, fixturing, first-article check) is carried by one part | Prototype, spare part, fit check |
| 2 to 10 pieces | Setup shared over a few parts; ordering several costs little more in total than one | Samples for testing, small assemblies |
| 10 to 500 pieces | Setup becomes a small share; machining time and material dominate | Pre-series, pilot runs, low-volume products |
| From 500 pieces | Optimized programs and dedicated fixtures lower the machining time per part | Series production, repeat orders |
Every quote shows the price per piece for each quantity you ask for, so you can see where the price drops.
When a minimum charge can apply
- Surface treatments. Anodizing, plating and some coatings are done by specialized partners who can charge a minimum lot price. For one or two parts this can be a large part of the total. It is always shown as a separate line in the quote.
- Special materials. Some alloys and engineering plastics are only sold in full bar lengths or plate sizes. If your part needs one of those, the quote says so.
- Injection molded parts. Molding needs a mold, so it only pays off at larger quantities. For small quantities, CNC machining is usually cheaper overall, and we will tell you which process fits your volume.
Not sure which quantity to order? Ask for a quote with two or three quantities, for example 1, 10 and 50 pieces, and compare the price per piece. Upload your STEP file for an instant price or send your drawing.
Small batch for every stage
Small batch machining serves three different needs: proving a new design, bridging the gap to series production, and keeping existing equipment running. The machines, the process and the quality checks are the same in each case. Only the quantity changes.
- Any machinable metal or engineering plastic
- Free DFM review before machining starts
- Design changes without tooling cost
- Production materials and finishes
- First article measured before the batch
- Same program and fixtures for repeat orders
- From 1 piece, no minimum order
- Machined to the original tolerances
- Reorder the same part when you need it
Lead time depends on material, finish and quantity, and is confirmed in every quote.

Good Fit
Small Batch CNC Is Ideal When:
✔ You need prototypes or samples before committing to production tooling
✔ Your volumes are naturally low (1–200 pcs per order)
✔ The design may still change — no expensive tooling to remake
✔ You need spare or replacement parts on demand
✔ You require a specific material or tight tolerance not achievable by injection moulding
✔ Speed matters — 5–10 day lead time vs. 35–45 days for injection tooling
✔ You’re running a pilot batch before scaling to volume production
Poor Fit
Consider Alternatives When:
X You need tens of thousands of identical plastic parts. Injection moulding is cheaper at scale
X Part geometry is highly complex with undercuts best suited to casting or MIM
X Budget is the only constraint and tolerances are not critical. Consider sheet metal or 3D printing
X You need lightweight infill or structural foam — SLS or FDM may be better for non-functional prototypes
