Machine Tools: CNC Turning vs CNC Milling

I've had a few emails asking me which is better CNC milling or CNC turning – and this post aims to answer that question. I'll also provide you with some information on the differences between automatics and manual CNC machines

This article is not intended to be an exhaustive guide to either of these processes, but rather a simple overview for those who are looking for more information about these topics. If you're interested in learning more about the details, I recommend reading through our other articles on CNC Turning vs CNC Milling (with photos) and the Pros and Cons of Using a Computerized Machine Tool.

What is CNC Turning

CNC turning is a process that involves using computer numerical control (CNC) machines to shape and finish various materials, such as metals and plastics, into desired shapes and sizes.
This process is typically used in the manufacturing industry to produce precision parts and components for a wide range of applications, including automotive, automation, aerospace, medical, machinery, and industrial.
