# CNC Turning: Precision Machining for Complex Components
## What is CNC Turning?
CNC turning is a subtractive manufacturing process that uses computer numerical control (CNC) machines to create precise cylindrical components. This advanced machining technique rotates a workpiece while a stationary cutting tool removes material to achieve the desired shape and dimensions.
## How CNC Turning Works
The CNC turning process follows these key steps:
– A cylindrical workpiece is securely mounted on a rotating spindle
– The CNC machine interprets digital design files (typically CAD/CAM)
– Cutting tools approach the rotating workpiece to remove material
– The tools move along multiple axes to create complex geometries
– Automated processes ensure consistent precision throughout production
## Advantages of CNC Turning
