# 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 components. This subtractive manufacturing technique rotates a workpiece while a stationary cutting tool removes material to create symmetrical parts with tight tolerances.
How CNC Turning Works
The CNC turning process begins with a cylindrical workpiece mounted on a chuck that rotates at high speeds. As the material spins, computer-controlled cutting tools move along multiple axes to remove material precisely according to programmed specifications. Modern CNC lathes can perform complex operations including:
- Facing
- Turning
- Drilling
- Boring
- Threading
- Grooving
Advantages of CNC Turning
CNC turning offers numerous benefits for manufacturing precision components:
1. Exceptional Precision
With tolerances as tight as ±0.0002 inches, CNC turning produces parts with remarkable accuracy and repeatability.
2. High Efficiency
Automated operations allow for continuous production with minimal human intervention, significantly reducing cycle times.
