What is CNC Milling?
A computer numerical control CNC milling machine is a mill that uses computer code to understand where to make cuts. It uses multi-point cutting tools to craft workpieces and create a custom-designed product with different materials like metal, glass wood, and plastic.
Unlike manual milling, CNC milling can cut at different angles and can move along different axes.
What is CNC Turning?
CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. This is also called “subtraction machining” since it involves material removal.
Summarize
The difference between CNC turning and milling is which part actually moves – the machine itself or the raw material. CNC milling processes involve the material being held in place while the cutting tools rotate around it. CNC turning requires the tools to maintain in the same place while the material is rotated at speed to create the exact shape.
Here are a few more ways in which there is a difference between CNC turning and milling:
Tool Features: The cutting tool is single point for CNC turning and multi-point in milling.
Uses: CNC milling is better suited for machining flat and irregular surfaces, while CNC turning is mainly used for working on cylindrical or conical surfaces
Cutting: CNC turning involves continuous cutting, with the tool maintaining constant contact with the workpiece. CNC milling uses intermittent cutting, where the cutting teeth continuously engage and disengage from the raw material.
Chips: CNC milling always produces discontinuous chips, while CNC turning can produce discontinuous, continuous and fragmented chips.
