What Is CNC Turning?
CNC turning is a precision machining process used to create accurate cylindrical and concentric components by removing material from rotating stock. The controlled toolpaths deliver stable diameters, clean surface finishes, and consistent dimensional repeatability for both prototypes and production parts.
How CNC Lathes Operate
A spindle rotates the raw material while cutting tools shape external and internal features such as profiles, bores, grooves, and threads. This method ensures stable geometry and predictable accuracy.
Turning Configurations
Different types of lathes handle different levels of work, from basic turning of round parts to advanced machines that produce very small or complex shapes. Each type helps improve stability, tool control, and accuracy during machining.
Turning Workflow
The machine executes programmed feeds, speeds, and tool motions to achieve precise dimensions.

CNC Turning Design Guidelines
Effective design choices help reduce machining time, improve accuracy, and maintain stable part geometry during turning.
| パラメータ | 仕様 | なぜ重要なのか |
| Internal Radii | Avoid sharp corners; recommended radius: 2.6 × tool diameter. | Prevents tool vibration and ensures stability in deep pockets. |
| Threads & Tapped Holes | Depth = 3× Ø (small) or 4× Ø (larger threads). | Prevents tool breakage and ensures strong thread engagement. |
| 最小肉厚 | Metals: 0.3–1.0 mm / Plastics: 1.2–1.5 mm. | Prevents vibration, deflection, and machining marks. |
| Hole Sizes & Depth | Min diameter: 0.50 mm / Max depth: 4× diameter. | Ensures reliable chip evacuation and precision bore accuracy. |
| アンダーカット | Supports square, full radius, and dovetail profiles. | Using standard profiles reduces machining time and cost. |
| Text & Engraving | Min width: 0.6 mm / Min depth: 0.1 mm. | For turned parts, laser engraving is preferred for finer marking. |
| Avoid Over-Constraint | Design for stable surfaces and supported geometries. | Reduces the need for excessive fixturing and complexity. |
| DFM Review | Engineering check for manufacturability and tool access. | Ensures high-quality output and efficient production cycles. |

よくある質問
CNC旋盤加工
What file formats do you accept?
We accept all standard CAD and engineering formats used in CNC machining:
- STEP (.step / .stp)
- IGES (.igs / .iges)
- Parasolid (.x_t / .x_b)
- SolidWorks (.sldprt)
- DXF / DWG for 2D drawings
- PDF for dimensioned technical drawings
Providing a technical drawing with GD&T improves accuracy, especially for parts needing precision CNC turning.
What materials can be turned?
We machine a wide range of metals and engineering plastics commonly used in precision CNC turning. Metals include aluminum (6061, 7075), stainless steel (304, 316, 17-4), carbon steels, brass, copper, titanium, and high-temperature alloys such as Inconel. Plastics such as POM, Nylon, PEEK, PTFE, PVC, and ABS are also supported for custom CNC turned parts. Material selection is validated based on machinability, dimensional stability, and final application requirements.
What tolerances can you achieve?
Typical CNC turning tolerances are ±0.005″, while tight-tolerance CNC turning services can achieve ±0.001″ or better on critical diameters, shoulders, and mating surfaces. Roundness can be controlled to ≤ 0.002″, with concentricity typically held within ≤ 0.005″ depending on geometry and tool access. All tolerance requirements are confirmed during DFM review to ensure the design is manufacturable.
Do you offer live tooling?
Yes. Our CNC turning services include live tooling and multi-axis turning, enabling milling, drilling, slotting, and threading operations within a single setup. This improves concentricity, reduces tool changes, minimizes fixture requirements, and shortens lead time — especially for complex turned-milled components.
What surface finishes do you offer?
We provide a full range of finishing options for metal and plastic turned parts:
- As-turned
- ビーズブラスト
- パウダーコーティング
- Anodizing (Type II / Type III)
- Polishing / Electropolishing
- ブラックオキサイド
- Zinc & nickel plating
Finishes are selected based on durability, corrosion resistance, friction behavior, or cosmetic needs. Surface roughness can reach Ra 0.8 μm for high-precision turning applications.
