# 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:
– The workpiece is securely mounted on a rotating spindle
– The cutting tool moves along multiple axes to remove material
– The CNC machine follows programmed instructions to create the part
– The process continues until the final shape is achieved
## Advantages of CNC Turning
CNC turning offers several significant benefits for manufacturing complex parts:
### High Precision
Modern CNC lathes can achieve tolerances as tight as ±0.0002 inches (±0.00508 mm), making them ideal for precision components.
### Repeatability
Once programmed, CNC turning machines can produce identical parts with consistent quality, batch after batch.
### Material Versatility
