CNC Turning

CNC Turning refers to an automated precision manufacturing process in which a computer numerical control (CNC) system is programmed to drive the lathe spindle, rotating the workpiece while controlling the cutting tool to move along a predetermined path. This process performs cutting operations such as external cylindrical surfaces, internal holes, threads, and end faces on rotary parts.

What is CNC Turning?

CNC turning is a subtractive manufacturing process in which a metal rod is rotated while a cutting tool is precisely applied to the workpiece surface to remove excess material and form the final part. Our CNC lathes are equipped with live tooling, enabling the machining of flat features and holes, as well as both outside diameter (OD) and inside diameter (ID) threading.

Finished turned parts can be left with their original machined surface (with visible tool marks) or bead blasted for a more uniform texture. Once the production run is complete, all parts undergo strict inspection, are carefully packaged, and promptly shipped.

CNC turning FAQs

What Are The Advantages Of CNC Turning?2025-09-09T13:44:54+08:00

CNC turning is ideal for manufacturing cylindrical parts due to its high precision, efficiency, and cost-effectiveness. It offers tight tolerances, fast production speeds, and excellent repeatability, making it perfect for both small and large production runs. The process minimizes material waste and lowers labor costs, making it an economical choice.

What Parts Can Be Made With A CNC Turning Machine?2025-09-09T13:44:33+08:00

CNC turning is widely used to produce high-precision cylindrical components across various industries. Common parts include shafts, pins, axles, valve components, and surgical instruments, among others.

How Does CNC Turning Work?2025-09-09T13:44:07+08:00

For cylindrical components like pins, shafts, spacers, or any parts with rotational symmetry, CNC turning is often the most cost-effective machining method. Lathes create these parts quickly, accurately and with excellent repeatability. At Horizon, we provide high-quality CNC lathe services to meet your exact specifications.

What Is CNC Turning?2025-09-09T13:41:49+08:00

CNC turning is a cutting process where the primary motion is the rotation of the workpiece, and the auxiliary motion is the linear or curved feed of the cutting tool. Through the lathe spindle driving the workpiece to rotate and the coordinated targeted movement of the cutting tool, material is gradually removed from the workpiece, ultimately producing the desired product. This process is particularly suitable for manufacturing parts with revolved symmetric features.
Key Differences from CNC Milling

•​Differing Primary Moving Components: In CNC turning, the workpiece rotates while the cutting tool remains stationary or only performs linear feeds; in CNC milling, the cutting tool rotates, and the workpiece is either fixed or moved, allowing the tool to approach the workpiece from multiple directions for processing.
•​Suitability for Different Shapes: Due to the rotational nature of the workpiece, CNC turning excels at processing revolved surfaces (e.g., cylindrical surfaces, conical surfaces, arc surfaces, threads, etc.), typically achieving higher precision and better surface quality compared to milling. In contrast, milling is more flexible, capable of processing planes, complex curved surfaces, irregular profiles, and other non-revolved geometries.

CNC turning delivers dimensional accuracy of up to ±0.01mm or higher. Benefiting from its high degree of automation, it not only enables rapid prototyping but is also well-suited for mass production. By significantly shortening the production cycle, it helps you quickly verify samples and seize the first-mover advantage in the market.
