What is CNC Turning Service?
CNC (Computer Numerical Control) turning is a precision manufacturing process where a cutting tool removes material from a rotating workpiece to create cylindrical parts with exact specifications. Unlike CNC milling where the tool rotates, in CNC turning the workpiece spins at high speeds while stationary cutting tools shape the material.
CNC Turning vs. CNC Milling: Key Differences
| Feature | CNC Turning | CNC Milling |
|---|---|---|
| Workpiece Movement | Rotates continuously | Remains stationary |
| Tool Movement | Moves linearly | Rotates and moves |
| Ideal Geometry | Cylindrical, conical, threaded | Flat surfaces, complex 3D shapes |
| Typical Parts | Shafts, pins, bushings, fittings | Housings, brackets, molds |
| Surface Finish | Excellent on cylindrical surfaces | Excellent on flat/contoured surfaces |
| Production Efficiency | High for rotational parts | High for prismatic parts |
When to Choose CNC Turning
CNC turning is the optimal manufacturing method when your project involves:
– Rotational symmetry: Parts with circular cross-sections
– Cylindrical features: Holes, threads, grooves, and tapers
– High precision requirements: Tolerances to ±0.01 mm, tighter where the geometry allows
– Surface finish criticality: Smooth finishes for sealing or bearing surfaces
– Volume production: Consistent quality across thousands of parts
Our CNC Turning Capabilities
We run turning work from one-off prototypes through repeat production orders, on lathes with live tooling and sub-spindles where the part needs milled features or back-working.
Related processes: features a cutter cannot reach are cut on our wire EDM machines; tight shaft and bore fits, and finishes finer than milling can hold, come from CNC grinding. If you want the geometry proven before a production run, start with rapid prototyping and low-volume production.
Multi-Axis CNC Turning Centers
- 3-axis, 4-axis, and 5-axis CNC lathes
- Swiss-type CNC turning machines for precision micro-machining
- Live tooling capabilities for milling operations during turning
- Sub-spindle configurations for complete part machining in one setup
Precision & Tolerances
We consistently achieve precision levels that meet or exceed industry standards:
| Tolerance Type | Standard Tolerance | Precision Tolerance |
|---|---|---|
| Linear dimensions | ±0.05mm | ±0.01 mm |
| Diameter | ±0.025mm | ±0.003mm |
| Concentricity | ±0.05mm | ±0.01mm |
| Surface roughness (Ra) | 1.6 μm | 0.4 μm |
| Thread accuracy | Class 2A/2B | Class 3A/3B |
CNC Turning Capability
Numbers we hold routinely, and where a drawing needs a conversation first.
Maximum Swing
Ø 300 mm
Largest diameter over the bed. Bigger flanges are quoted case by case.
Bar Capacity
Ø 42 mm
Through the spindle. Swiss-type machines run Ø 20 mm bar for small precision parts.
Maximum Length
500 mm
Up to 1000 mm between centres on long shafts.
Surface Finish
Ra 0.8 – 1.6 µm
As-turned. Below that, grinding is the right next step, not more turning.
Minimum Wall Thickness
0.5 mm
Thin-walled sleeves need purpose-made workholding. Worth a conversation before quoting.

Frequently Asked Questions
What file formats do you accept for designs?
3D+2D drawings, preferred formats below:
- STEP (.stp)
- IGES (.igs)
- PDF drawings (with GD&T callouts)
What are your standard lead times?
Standard lead time is 2–4 weeks. Rush orders are confirmed case by case — tell us your deadline up front and we will say straight away whether we can hit it.
Do you offer design assistance?
We review every drawing before quoting. If we find a feature that cannot be machined as drawn, or one that adds cost without adding function, we point it out and suggest an alternative for you to confirm. If the drawing is machinable as it stands, we quote it as-is — we do not redesign parts that already work.
What is your minimum order quantity?
We don’t have a minimum order quantity. We can produce a single prototype or thousands of parts depending on your needs.
What is your return policy?
At MetaliCNC, every product goes through strict verification—from trial production and inspection testing to customer confirmation—before shipment. Our quality assurance process ensures that all parts meet the agreed specifications before delivery, minimizing the risk of nonconformities. We take pride in our precision and reliability, and every shipment is the result of a joint confirmation between our engineers and customers.
In the rare event that a delivered part does not meet the agreed specifications, we follows a transparent and responsible after-sales process. Customers can submit a claim with inspection data, photos, or videos clearly indicating the nonconforming features. Our quality team will review the case within 48 hours to identify root causes—whether related to design, machining, material, or logistics.
Based on the assessment, we provide appropriate solutions such as rework, remake, partial refund, or credit, in line with the order terms. All cases are fully documented and backed by inspection records to ensure traceability. To help us resolve issues faster, customers should retain original samples and all supporting evidence. Each case also feeds into our continuous improvement system to further enhance product quality and customer satisfaction
