# CNC Turning: Precision Machining for Complex Parts
## What is CNC Turning?
CNC turning is a subtractive manufacturing process that uses computer numerical control (CNC) machines to create precise cylindrical parts. The process involves rotating a workpiece while a single-point cutting tool removes material to achieve the desired shape and dimensions.
## How CNC Turning Works
The CNC turning process follows these basic steps:
– A cylindrical workpiece is mounted on a rotating chuck or spindle
– The cutting tool moves along two axes of motion (X and Z) to remove material
– The CNC machine follows programmed instructions to create the desired geometry
– Coolant is often applied to reduce heat and improve surface finish
