What Is CNC Turning?

CNC turning is best suited for custom parts with round, cylindrical, or concentric features.

CNC turning is a machining process where the workpiece rotates and a cutting tool removes material to form the required shape. It is commonly used for shafts, pins, bushings, sleeves, threaded parts, and other components that depend on controlled diameters and concentric features.

It is especially suitable for parts that require stable diameters, smooth outer surfaces, and repeatable machining quality.
