What Is CNC Turning?
CNC turning is a machining process that uses a rotating workpiece and a fixed cutting tool to create round parts like shafts, bushings, and threaded rods. It’s ideal for parts that are symmetric around a central axis.
Common in industries like automation, aerospace, electronics, and medical devices, CNC turning offers fast production, excellent surface finishes, and tight tolerances — making it perfect for both prototypes and large-volume parts.
Materials
We support a wide range of metals and plastics to meet different project needs — from strength and durability to weight and appearance.
The table below lists the most common materials we work with, but we can also machine others — including titanium, PEEK, PTFE, or customer-supplied materials upon request.
| Material | Properties | Typical Use |
|---|---|---|
| Aluminum (6061, 7075) | Lightweight, corrosion-resistant, easy to machine | Enclosures, mechanical parts, heat sinks |
| Stainless Steel (303, 304, 316) | High strength, corrosion-resistant | Shafts, fittings, medical parts |
| Brass | Easy to machine, attractive finish | Connectors, decorative parts |
| Mild Steel / Alloy Steel | Durable, cost-effective | Brackets, structural components |
| POM (Delrin) | Hard, low-friction, dimensionally stable | Bushings, sliding parts |
| Nylon | Flexible, tough, wear-resistant | Spacers, insulating parts |
| ABS | Good impact strength, easy to process | Prototypes, covers, housings |
Not sure which material is best for your part? Just ask — we’ll help you choose the right one.
Surface Finishing Options
| Finish Type | Description | Compatible Materials |
|---|---|---|
| As-Machined | Slight tool marks, ±0.01mm tolerance | All metals & plastics |
| Anodizing (Type II) | Decorative, corrosion-resistant, color options | Aluminum |
| Anodizing (Type III / Hardcoat) | Wear-resistant, thick layer for harsh use | Aluminum |
| Electropolishing | Brightens and smooths stainless surfaces | Stainless steel |
| Passivation | Improves corrosion resistance | Stainless steel |
| Zinc Plating | Cost-effective corrosion protection | Steel |
| Powder Coating | Durable colored coating | All metals |
| Brushing / Polishing | Improves surface appearance | Aluminum, brass, stainless steel |
| Custom Finishes | Let us know what you need | On request |
Tolerances
Our standard tolerances for CNC turned parts follow ISO 2768-mK or customer-specified drawings. For most applications, the following tolerances apply:
- General tolerance for turned dimensions: ±0.05 mm (±0.002″)
High-precision tolerance capability: up to ±0.01 mm (±0.0004″), upon request
Standard thread tolerances: per ISO or ANSI/ASME thread specifications
Surface finish (as-turned): 3.2 μm Ra or better
Concentricity and runout: dependent on geometry, can be held to < 0.02 mm for precision parts
If your part requires tighter tolerances or has critical features (like fits, threads, sealing surfaces), please specify them clearly in your drawings. We review every order to ensure manufacturability and cost-effectiveness.
Applications
Automation & Machinery
Custom shafts, bushings, spacers, and couplers used in assembly lines and mechanical systems.
Medical Devices
Small precision parts like pins, inserts, and sensor housings machined from stainless steel or PEEK.
Aerospace Components
Lightweight turned parts such as threaded fasteners and alignment pins with tight tolerances.
Electronics & Connectors

Key Benefits of CNC Turning
Highly Efficient for Round and Axial Parts
CNC turning is the best choice for round components like shafts, bushings, spacers, and threaded parts — offering great speed and repeatability, even for complex designs.
Tight Tolerances & Smooth Surface Finish
Our CNC lathes can achieve tolerances down to ±0.01 mm and deliver consistent, clean surfaces — ideal for press fits, sealing surfaces, and moving parts.
Cost-Effective for Prototypes & Production
Turning is one of the most efficient ways to machine rotational parts, helping you cut lead time and lower costs — whether you’re ordering 10 pieces or 10,000.
Versatile in Materials & Design
We work with aluminum, stainless steel, brass, POM, nylon, and more — handling features like grooves, undercuts, tapers, and other custom geometries with ease.
Frequently Asked Questions
What materials do you support for CNC turning?
We work with a wide range of metals and plastics — aluminum, stainless steel, brass, copper, POM (Delrin), nylon, and more. Not sure which one to use? Just ask — we’ll help you choose.
Can you handle low-volume or prototype orders?
Absolutely. We support small runs starting from just 10 pieces. Perfect for testing a design or starting small.
What tolerances can you achieve?
Standard tolerance is ±0.05 mm, but we can go as tight as ±0.01 mm if needed. Just let us know in your drawing.
Can you provide surface finishes?
Yes — we can arrange anodizing, plating, polishing, sandblasting, powder coating, and more. Tell us the finish you need, and we’ll make it happen.
How long does it usually take?
Samples usually take 3–7 days. Production lead time depends on the part and quantity — but we always aim to deliver fast and on time.
Can you work without a 3D file?
Yes. If you have a 2D drawing, a sketch, or even a sample photo, send it over. We’ll review and confirm what’s possible.
Do you ship internationally?
Yes, we ship worldwide — via DHL, FedEx, or other couriers. Let us know your country and shipping preference, and we’ll take care of the rest.
How do I get a quote?
Just send us your 3D file (STEP/STL), quantity, material, and any special requirements. You’ll get a quote within 12 hours — often faster.
Want a fast quote? Just upload your file on our form — we’ll take care of the rest.
Can you provide material certificates or inspection reports?
Yes. We can include RoHS certificates, material composition reports, and full QC inspection reports if needed — just mention it when you place the order.
What file formats do you accept?
STEP, STP, STL, IGES, PDF — we work with most standard formats. If you’re unsure, just send what you have.
Do you provide samples before production?
Yes, we can provide a prototype or sample run for confirmation — especially helpful if your part has special requirements.
What if there’s a quality issue?
We take quality seriously. If something’s wrong, we’ll refund or remake — no hassle. Your satisfaction comes first.
