What is CNC Turning?
CNC turning is a manufacturing process in which bars of material are held in a chuck and rotated while a cutting tool, typically a single-point cutting tool, is moved parallel to the axis of rotation to create cylindrical shapes. The process is controlled by a computer using CAD/CAM programming.
Unlike milling, where the tool rotates, in turning, the workpiece rotates while the cutting tool remains stationary. This makes turning ideal for creating parts with cylindrical symmetry.
Common Turning Operations
- Facing: Creating a flat surface perpendicular to the rotation axis
- Turning: Reducing the diameter of the workpiece
- Boring: Enlarging an existing hole
- Threading: Creating external or internal threads
- Grooving: Cutting recesses or grooves into the workpiece
- Parting: Cutting off the completed part from the stock material
