What Is CNC Turning?
CNC turning is a subtractive machining process in which the workpiece rotates in a spindle while a stationary cutting tool moves along it, removing material to produce a part that is round about its axis. It is the mirror image of milling, where the tool spins and the part stays still. Turning is the right process for precision turned parts — shafts, pins, bushings, sleeves, rings, threaded bodies and connector contacts — anything defined by diameters, tapers, grooves and threads. Live tooling adds powered mills and drills to the turret so cross-holes and flats can be cut in the same clamping; Swiss-type machines add a guide bushing beside the tool so long slender parts can be held to a micron without deflecting.
How accurate is CNC turning?
General features are held to ±0.01 mm under ISO 2768-m. Precision diameters are held to ±0.005 mm on live-tool lathes, and Swiss-type setups with in-process gauging reach ±0.001 mm on critical journals. Cpk ≥1.67 is maintained on those dimensions and verified on Zeiss CMM equipment.
Turning or milling — which does my part need?
If the part is round about one axis, turn it — it is faster and cheaper than milling the same geometry. If it is prismatic, multi-faced, or built from pockets and contours, mill it. Parts with both are turned first and milled second, or cut in one clamping on a live-tool lathe. Compound angles, undercuts and contoured faces that no lathe can reach move to multi-axis machining. Full comparison, with cost data.
2-axis, live tool or Swiss-type?
Diameter and slenderness decide it. Parts above roughly Ø32 mm with no off-axis features run 2-axis at the lowest cost per part. Parts needing cross-holes, flats or keyways run live-tool in one clamping. Parts under Ø32 mm, or longer than about eight times their diameter, need Swiss-type turning — a standard lathe will push them off-centre.
What drives the price of a turned part?
Cycle time first, then the number of setups, then tolerance callouts tighter than the function needs, then material machinability, then cosmetic finishing. A cross-hole that forces a second operation on a manual mill usually costs more than the bar it is drilled into — our DFM review flags that before you commit. What tolerance really costs.
2-Axis, Live Tool and Swiss-Type CNC Turning: What Each One Is For
Three distinct turning technologies — each optimised for different part geometries, diameter ranges, and tolerance requirements. Our engineering team recommends the right process for your application. If your part is prismatic rather than round, see CNC milling services instead, or compare milling vs turning on cost and geometry.
2-Axis CNC Turning
The cost-effective workhorse for shafts, pins, bushings, and cylindrical components. X and Z axis movement produces consistent ±0.01mm diameters to ISO 2768-m, tapers, grooves, and threads at high throughput — ideal for medium to high-volume production.
- Spindle speed up to 4,500 RPM
- Roughing and finishing in one chucking
- All thread forms: Metric, UNC, UNF, BSP, NPT
- Bar-fed automation for 24/7 production
Live Tool CNC Turning
Combines turning and milling in a single setup using powered turret tools. Y-axis capability enables off-centre milling, cross-drilling, and flat features on cylindrical parts — eliminating secondary operations, reducing setups by up to 50%, and improving inter-feature positional accuracy.
- Y-axis for off-centre milling and keyways
- Simultaneous milling and turning operations
- Cross-drilling, tapping, and slotting in one setup
- Reduces handling errors and re-referencing
Swiss-Type CNC Turning
Purpose-built for small-diameter precision parts (Ø1–32 mm). A guide bushing positioned immediately adjacent to the cutting zone provides ultra-rigid support, enabling ±0.001mm tolerances on long slender components that would deflect on a standard lathe. Essential for medical screws, dental implants, watch components, and electronic pins. See the buyer's guide to Swiss machined screws, shafts and pins.
- Guide bushing for near-zero deflection
- Live tooling with backworking capability
- Concentricity to 0.001 mm achievable
- Full biocompatibility documentation for medical

A transparent, engineering-led workflow built for professional procurement teams. Average total cycle: 3–25 business days depending on complexity, material, and volume.
CNC Turning Design Guidelines: L/D Ratio, Grooves, Bores and Threads
These limits come from tool geometry and workpiece rigidity, not from house policy — they are what a lathe can physically hold. Designing to the standard column keeps a part in the lowest cost band. The achievable column is what MW+ will quote when the function demands it, usually with a steady rest, a Swiss-type setup, specialist tooling or slower feeds. Every RFQ gets a free DFM review against these rules within 24 hours.
| Feature | Standard (lowest cost) | Achievable | What drives the limit |
|---|---|---|---|
| Length-to-diameter ratio, unsupported | 3 : 1 | 8 : 1 with tailstock or steady rest | Past 3:1 the bar deflects away from the tool and the diameter tapers along its length |
| Length-to-diameter ratio, Swiss-type | 20 : 1 | 30 : 1+ | The guide bushing supports the bar millimetres from the cutting edge, so slenderness stops mattering |
| Turned diameter | Ø1 – 500 mm | Ø0.5 mm · Ø800 mm heavy-duty | Below Ø1 mm is micro-machining; above Ø500 mm needs a heavy-duty lathe |
| Part length | 1,000 mm (2-axis) · 400 mm (Swiss) | — | Bed length and tailstock travel. Bar capacity is confirmed per part — send the model with your RFQ |
| Wall thickness, turned sleeves and tubes | 0.5 mm | 0.3 mm | Thin walls distort under chuck pressure; below 0.5 mm needs soft jaws or an expanding mandrel |
| Internal corner radius at shoulders | 0.4 mm | 0.2 mm | A turned shoulder carries the tool nose radius. A genuinely sharp corner needs a separate grooving pass |
| Groove width | 0.5 mm | 0.3 mm | Grooving-blade width. Keep depth under 2× the width or the blade deflects and chatters |
| Bore diameter | Ø1.0 mm | Ø0.5 mm | Drill rigidity and chip evacuation at small diameters |
| Bore depth | 3 × diameter | 10 × diameter, gun-drilled | Boring-bar overhang. Past 3× the bar chatters and the bore bells out |
| Threads | M2 – M64 | M1 – M200, plus UNC / UNF / BSP / NPT / ACME | Always allow a thread relief at least 1.5× the pitch, or the tool has nowhere to run out |
| Chamfers | 0.5 × 45° | 0.2 × 45° | Chamfer every entering edge — it is free on a lathe and it prevents burrs and assembly damage |
| Knurling | Straight or diamond, 0.5 – 1.5 mm pitch | — | Knurling raises the diameter by roughly a third of the pitch — allow for it on the drawing |
| General tolerance | ±0.01 mm (ISO 2768-m) | — | Apply to every non-functional feature and reserve tight callouts for the ones that carry the fit |
| Precision diameters | ±0.005 mm | — | Live-tool lathe with in-process gauging and CMM verification |
| Critical journals, Swiss-type | — | ±0.001 mm | Guide-bushing setup, single clamping, Cpk ≥1.67 monitored across the run |
| Surface finish | Ra 3.2 µm as-turned | Ra 0.4 µm fine-turned · Ra 0.1 µm polished | Finer than Ra 0.4 µm is a separate grinding or polishing operation, not a turning pass |
| These are process limits set by tool geometry and workpiece rigidity, and they apply to any competent turning shop. What differs between suppliers is what happens when you need the achievable column: MW+ quotes it with the setup and inspection cost stated up front rather than discovering it after the PO. | |||
Five things that make a turned part cost more than it needs to
- A tolerance the fit does not need. Tightening a whole drawing from ±0.01 mm to ±0.005 mm can add 20–40% to unit cost. Tighten the journal that carries the bearing and leave the rest at ISO 2768-m — see what actually drives lathe pricing.
- A slenderness ratio past 8:1 on a standard lathe. It forces a steady rest, a second setup, or a move to Swiss-type. Say so on the drawing and it gets quoted on the right machine first time.
- Off-axis features quoted as a second operation. Cross-holes, flats and keyways are nearly free on a live-tool lathe and expensive on a separate mill. Group them so one clamping does the work.
- Material chosen by habit. Free-machining brass C360 and 303 stainless cut several times faster than 316L, Ti-6Al-4V or Inconel 718. Where the application allows it, the cheaper alloy is cheaper twice.
- No thread relief, no chamfer. Both are free when they are on the drawing and both become hand-deburring operations when they are not.

Standard 2-axis CNC turning achieves ±0.01mm. Live tool turning holds ±0.005mm. Swiss-type turning routinely achieves ±0.001mm on critical bearing diameters, with concentricity held to 0.001mm on dedicated setups. Cpk ≥1.67 is maintained on critical dimensions. All tolerances verified with Zeiss Contura G2 CMM and documented in FAI or PDF dimensional reports.
Standard CNC turning handles up to Ø500mm diameter and 1,000mm length. Swiss-type CNC turning covers Ø1–32mm precision parts. Heavy-duty lathes handle diameters up to Ø800mm for large industrial components such as wind turbine shafts and pump impellers.
2-axis CNC turning moves the tool in X and Z to produce cylindrical shapes — best for shafts, pins, and bushings at high volume. Live tool turning adds powered milling, drilling, and tapping tools on the lathe turret plus C-axis and optional Y-axis, enabling off-axis features in a single setup. Swiss-type turning uses a guide bushing adjacent to the cutting zone for ultra-rigid support, enabling ±0.001mm on small-diameter parts (Ø1–32mm) such as medical screws, pins, and electronic contacts.
Over 70 materials: Aluminium (6061-T6, 7075-T6, 2024, 6082, 5083), Stainless Steel (303, 304, 316L, 17-4PH, 420, 440C), Carbon and Alloy Steel (1018, 1045, 4140, 4340, 8620), Copper and Brass (C110, C360, C932 Bronze, Beryllium Copper), Titanium (Ti-6Al-4V Grade 5), Superalloys (Inconel 718, Hastelloy C276, Monel K500), and Engineering Plastics (PEEK, PTFE, Delrin/POM, Nylon 6/66, Ultem PEI).
