What is CNC Turning? How CNC Turning Works
CNC turning is a subtractive process ideal for producing cylindrical or spherical components with high accuracy. In this process, the workpiece is clamped in a spindle and rotated while a stationary cutting tool shapes it to the desired geometry.
Using programmed G-Code, raw stock is loaded into the chuck of the lathe spindle. As the spindle rotates, fixed cutting tools perform operations such as facing, threading, knurling, drilling, boring, and taper turning. Once complete, the finished part is separated from the stock and prepared for post-processing.
This automation allows CNC lathes to repeat operations efficiently with minimal setup time, ensuring consistent accuracy and cost-effectiveness across production runs.

CNC Turning Design Guidelines
Optimize your CNC turning projects with TUOWEI’s expert design guidelines. Our engineering team ensures every part is manufacturable, precise, and cost-efficient from prototype to production.
| Features | Recommended size |
|---|---|
| Radii | Minimum internal radius of 0.5 mm recommended. Larger radii (up to 3 mm or more) enhance tool access and reduce stress concentrations. |
| Threads and Tapped Holes | External and internal threads can be precisely cut. Standard thread sizes from M1.6 and larger are feasible. Ensure a minimum thread length of 1.5× the diameter for stability. |
| Minimum Wall Thickness | Minimum wall thickness: 0.8 mm for metals, 1.5 mm for plastics to maintain structural integrity without compromising the machining process. |
| Text | Engraving should have a minimum character height of 2 mm and a depth of at least 0.5 mm to ensure legibility after machining. |
| Holes | Minimum hole diameter: 0.5 mm. For deep holes, maintain a diameter-to-depth ratio of 1:10 to prevent tool deflection and ensure hole quality. |
Surface Finishes For CNC Turning Services
Here are some surface finishing techniques that are commonly used to enhance the quality and performance of the machined parts:
Polishing smooths the surface, providing a high-gloss finish that improves both appearance and resistance to wear.
This process adds a protective oxide layer to metal surfaces, increasing corrosion resistance and enhancing aesthetic appeal.
Bead blasting involves spraying fine beads onto the surface to create a smooth, matte finish with a uniform texture.
Electroplating adds a thin metal coating to a surface, offering enhanced corrosion resistance, wear protection, and improved conductivity.
Lapping is a precision process that improves surface flatness and smoothness, reducing surface roughness for high-tolerance applications.
Shot peening involves bombarding the surface with small spherical media, improving fatigue resistance and reducing stress concentrations.

Frequently Asked Questions
CNC Turning
What’s the difference between CNC milling and CNC turning?
Both CNC milling and turning are subtractive manufacturing methods, but their approach differs.
In CNC milling, the workpiece remains fixed while the cutting tool moves across multiple axes to create intricate features such as holes, slots, and pockets, ideal for complex, non-cylindrical parts.
In CNC turning, the workpiece rotates while a stationary cutting tool shapes it, making it the most efficient method for producing cylindrical parts like bolts, rings, and rods.
At TUOWEI, we combine both processes when required, delivering cost-efficient, high-quality parts tailored to your design needs.
What is a CNC turning center, and what parts can it make?
A CNC turning center is an advanced, computer-controlled machine used to produce cylindrical parts with high precision. TUOWEI’s turning centers are capable of performing multiple operations, facing, drilling, threading, boring, grooving, and contouring within a single setup. This versatility allows us to deliver complex geometries and high-volume production of parts such as screws, bushings, shafts, and precision pins, ensuring both efficiency and repeatable accuracy.
Can TUOWEI produce plastic turned parts
Yes. TUOWEI’s CNC turning services handle both metal and plastic materials with equal precision. Common plastics we machine include ABS, Nylon, Polycarbonate, PTFE (Teflon), and Acetal. Each plastic has unique benefits—for example, Nylon offers durability and wear resistance, while Acetal provides dimensional stability and excellent machinability. By optimizing cutting speeds and tooling, we ensure that every plastic-turned part is manufactured with high accuracy and surface quality.
What parts can CNC turning produce?
CNC turning at TUOWEI specializes in manufacturing cylindrical and symmetrical components around a central axis. Typical parts include shafts, pins, rods, bushings, pulleys, and threaded components. The process also enables the creation of internal bores and complex contours, delivering tight tolerances and smooth finishes. These qualities make CNC turning ideal for automotive, aerospace, medical, and industrial machinery applications requiring precise fits and reliable performance.
