CNC Turning vs CNC Milling — What's the Difference?
If you're sourcing precision machined components for the first time, you may have come across the terms CNC turning and CNC milling and wondered what the difference is. Both are core CNC machining processes, but they work in fundamentally different ways and are suited to different types of components.
What is CNC Turning?
CNC turning involves rotating the workpiece at high speed while a cutting tool moves along its length to remove material. This process is ideal for producing cylindrical or round components — shafts, bushes, flanges, sleeves and stepped profiles are all typical turning applications.
At our Stockport facility, our CNC turning services cover a wide range of diameters and materials. We can produce everything from simple turned bushes to complex multi-step profiles with grooves, threads and undercuts — all to tight tolerances.
What is CNC Milling?
CNC milling works differently — the workpiece is held stationary (or repositioned) while a rotating cutting tool removes material as part of our CNC milling service. Milling is used to produce flat surfaces, pockets, slots, holes and contoured profiles that can't be achieved by turning alone.
Milling is particularly suited to prismatic components — blocks, plates and housings — where features need to be machined on multiple faces.
Which Process Do You Need?
The answer depends on the geometry of your component:
- Round or cylindrical parts → CNC Turning
- Flat, square or complex profile parts → CNC Milling
- Parts needing both → We can combine both processes
