CNC turning remains essential for producing high-precision cylindrical components efficiently. PlasticHubs delivers precise and reliable CNC turning services tailored for complex geometries, tight tolerances, and fast-moving production demands.
CNC turning is a subtractive machining process in which a cutting tool removes material from a rotating workpiece to create precise cylindrical or conical shapes. It is commonly performed on CNC lathes and turning centers—machines engineered to maintain stable rotation, repeatable tool movements, and consistent dimensional accuracy.
These CNC turning machines can handle everything from simple shafts to complex stepped geometries, making CNC turning an ideal method for producing bushings, spacers, threaded parts, and other round components with reliable precision.
CNC turning operates on a straightforward principle: the workpiece rotates at controlled speeds while a stationary cutting tool moves along programmed paths to remove material and shape the part. Through precise coordination of spindle rotation, tool positioning, and feed rates, the machine forms accurate external and internal features. Modern turning centers automate these motions seamlessly, enabling consistent production of round, threaded, or contoured components with minimal manual intervention.
Here are the CNC Turning we can do. If your project calls for a custom turning solution, our team is ready to assist and provide the most suitable approach.
Taper turning creates conical profiles by gradually changing the diameter along the workpiece. This method is ideal for connectors, pins, and components requiring controlled angular transitions.
Ball turning forms precise spherical or curved surfaces using a dedicated ball-turning attachment, often used for joints, ornamental parts, and motion components requiring smooth radius transitions.
Chamfer turning cuts angled edges at the ends of a part to remove sharp corners, improve assembly alignment, and enhance overall component safety and appearance.
Parting cleanly separates a finished component from the raw stock by cutting deep into the rotating material, ensuring a precise final length with a smooth cutoff surface.
Thread turning produces internal or external threads directly on the lathe, offering accurate pitch, depth, and profile for both standard and custom thread forms.
Boring enlarges existing holes with high precision, achieving exact internal diameters and fine finishes for bushings, housings, and any component requiring stable internal geometry.
Knurling imprints patterned textures, often diamond or straight lines, onto cylindrical surfaces to improve grip, enhance aesthetics, or prepare the surface for press-fit applications.
Grooving creates narrow, controlled recesses on the outer or inner diameter, used for O-rings, retaining clips, or functional relief areas.
Facing smooths and squares the end of a workpiece by cutting across the face, ensuring a flat, clean, and dimensionally consistent surface.
Drilling on a turning center forms accurate axial holes by feeding a stationary drill into the rotating part, establishing the base for subsequent boring or threading operations.

This CNC turning service delivers high-precision parts with tolerances of ±0.005 mm, handling workpieces up to 1500 mm in length and 500 mm in diameter, with minimum feature sizes down to 1 mm. There is no minimum order quantity (starting from 1 piece), and mass production orders are completed in 15 business days or less.
CNC turning delivers excellent accuracy on diameters, tapers, and threads because the part rotates on a stable axis, ensuring consistent concentricity and tight tolerances.
For components that are round or symmetric, turning removes material faster and more uniformly than most other processes, improving overall production efficiency.
The continuous rotation of the workpiece naturally produces clean, refined surfaces, making turning ideal for shafts, bushings, and sealing interfaces.
Fast cycle times, easy automation, and minimal tool changes allow turning to scale well, keeping unit costs low for both small and high-volume runs.
Here are the primary materials we support for CNC turning. Each material brings its own machining characteristics, allowing us to match the right solution to your part’s performance needs.
Here is a list of standard CNC turning surface finishes available at PlasticHubs. For custom surface finishes, please don’t hesitate to contact us.
Produces a clean, uniform appearance directly from the cutter, with visible but fine tool marks and dependable dimensional accuracy.
Creates a smooth, glossy surface, ideal for clear plastics or parts that require improved transparency and refined visual quality.
Applies a matte, even texture that reduces glare and hides minor machining marks, suitable for both aesthetic and functional surfaces.
Offers customizable colors and finishes while adding a protective coating, often used for housings, prototypes, and display parts.
Used for metal components, providing enhanced corrosion resistance, improved hardness, and a uniform decorative appearance.
Adds a thin metallic layer to metal parts for increased wear resistance and visual appeal, often used in premium or high-contact components.
Delivers precise marking of logos, text, or identification codes without affecting part integrity, suitable for both plastics and metals.
CNC turning supports a broad range of industries by delivering precise rotational components essential to mechanical systems and engineered assemblies. From electronics and automotive to medical devices and industrial equipment, turned parts play a vital role in ensuring reliability and performance across many applications.
PlasticHubs turned out some of the cleanest nylon parts we’ve ever ordered. Dimensions were spot-on, and the team kept us updated the whole way. Solid experience.
