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.
