Overview: What is CNC Turning?
CNC turning is a manufacturing process used to create cylindrical parts by rotating the workpiece against a stationary cutting tool. The tool removes material to achieve the desired shape and dimensions.
Computer numerical control (CNC) system that automatically controls the tool’s movement path, rotational speed and feed rate according to pre-programmed instructions (G-code), thereby producing the desired shapes—such as outer cylinders, inner bores, end faces, tapers and threads.
On high-precision lathes, ultra-smooth surfaces with a roughness of Ra 0.04–0.01 μm can be achieved by high-speed cutting of non-ferrous metals using finely honed diamond cutting tools, with machining accuracy reaching grade IT7–IT5.
CNC turning is the cornerstone of modern manufacturing. This process is indispensable for producing everything from simple screws to complex aero-engine shafts.
