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.

Maximum CNC Turning Capabilities

Our CNC turning capabilities are engineered for consistent accuracy, smooth finishes, and efficient production cycles across metal and plastic components. Each setup supports reliable machining for both prototypes and large-batch manufacturing.

Surface Finishing for CNC Turning

Precision-turned parts benefit from specialized surface treatments that enhance strength, durability, and overall performance. These treatments are ideal for optimizing the functionality of shafts, bushings, and cylindrical components.

Como moído

The quickest and most economical option, leaving visible tool marks and potentially sharp edges or burrs. Surface roughness is approximately 125 µin Ra, and burrs can be removed upon request.

Hard Chrome Plating

A thick chromium coating that boosts hardness, wear resistance, and durability. Perfect for high-stress parts like shafts and pistons.

Niquelagem

A thin, electroplated nickel layer that enhances wear and corrosion resistance. Provides a bright, attractive finish for functional parts.

Óxido preto

A chemical treatment that creates a dark, matte black surface on steel parts. Offers mild corrosion resistance and reduces light reflection.

Polished Finish

A smooth, glossy finish achieved by mechanical buffing. Ideal for decorative parts requiring enhanced shine and low roughness.

Brushed Finish

A linear, satin-like texture created using abrasive belts or brushes. It reduces minor imperfections and offers a clean, decorative appearance.

Custom

Need a specific finish? Submit an RFQ, and we’ll work with you to find a tailored solution for your project.

Bead Blast

Creates a smooth, matte finish by media-blasting, typically with glass beads, offering an improved aesthetic and uniform surface texture.

Key Features of CNC Turning

Heading	Descrição

CNC Turning Design Guidelines

Effective design choices help reduce machining time, improve accuracy, and maintain stable part geometry during turning.

Parâmetro	Especificação
Internal Radii	– Avoid sharp internal corners; CNC tools naturally create radii. – Recommended internal radius: 2.6 × tool diameter. – Deep pockets: tool length should not exceed 10× diameter for stability.
Roscas e furos roscados	– For threads Ø1.5-6 mm: depth = 3× diameter. – For threads Ø6 mm: depth = 4× diameter. – Custom threads and fine-pitch threads available upon request. – For turned parts, laser marking is recommended for identification.
Espessura mínima da parede	– Metals: 0.3-1.0 mm. – Plastics: 1.2-1.5 mm. – Thin walls increase vibration, deflection, and machining marks.
Hole Sizes & Depth	– Minimum hole diameter: 0.020″ (0.50 mm) depending on tool availability. – Recommended maximum depth: 4× diameter for reliable chip evacuation. – For precision bores, reaming or boring improves tolerance accuracy (±0.002″ typical).
Cortes inferiores	– Supported profiles: square, full radius, dovetail, and custom reliefs. – Specialized tools may increase machining time or cost.
Text & Engraving	– CNC milling text: minimum 0.6 mm width and 0.1 mm depth. – For turned parts or finer marking, laser engraving is preferred.
Avoid Over-Constraint	– Parts should not require excessive fixturing; design for stable flat surfaces and supported geometries. – Avoid ultra-thin features, unsupported tabs, and unnecessary complexity.
DFM Review Available	– Our engineers check your part for manufacturability, tolerance risks, tool access, and stability — ensuring efficient machining and high-quality output.

Perguntas mais frequentes

Torneamento CNC

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:
1. As-turned
2. Bead blasting
3. Revestimento em pó
4. Anodizing (Type II / Type III)
5. Polishing / Electropolishing
6. Óxido preto
7. 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.
How do you ensure concentricity and runout accuracy?
Concentricity and runout are controlled through:
1. Precision collets, soft jaws, and balanced workholding
2. Single-setup machining when possible
3. Live tooling alignment verification
4. Controlled toolpath strategies for rotational accuracy
5. CMM inspection of critical features
  These methods allow precision CNC turning of parts that require tight alignment across multiple diameters or threaded sections.
Can you handle both prototypes and mass production?

Yes. We support rapid prototype machining, low-volume batches, and high-volume production. Prototypes benefit from flexible tooling and fast machine setup, while production orders leverage automated turning centers, multi-axis operations, and consistent process control. Both small and large quantities receive identical quality assurance steps.
How fast is delivery?

Prototype turned parts can ship in as fast as 1–3 days, depending on complexity, tolerances, and finishing requirements. Low-volume runs typically take 5–10 days, while mass production depends on part count and process routing. All orders follow a predictable schedule, with real-time communication throughout manufacturing.
