# CNC Turning: Precision Machining for Complex Components
What is CNC Turning?
CNC turning is a highly precise machining process that uses computer numerical control (CNC) to shape cylindrical parts. This subtractive manufacturing method rotates a workpiece while a cutting tool removes material to create symmetrical components with tight tolerances.
How CNC Turning Works
The CNC turning process begins with a cylindrical workpiece mounted on a chuck. As the material rotates at high speeds, stationary cutting tools move along multiple axes to remove material. Modern CNC lathes can perform complex operations including:
- Facing – creating flat surfaces
- Taper turning – producing conical shapes
- Grooving – cutting narrow channels
- Threading – creating screw threads
- Drilling – making axial holes
Advantages of CNC Turning
CNC turning offers numerous benefits for manufacturing precision components:
- High accuracy: Can achieve tolerances within ±0.005 inches
- Repeatability: Produces identical parts with minimal variation
- Complex geometries: Capable of creating intricate profiles
- Material versatility: Works with metals, plastics, and composites
- Efficiency: Faster than manual machining with minimal waste
