CNC Turning: What is it Used for and How is it Done?

If you have ever looked into or are currently looking into getting metal parts and components specially made for a project you’re undertaking, then you may have heard of CNC turning. Whether you have or not, unless you are well-versed in the lingo involved with metal fabrication, it is likely that you aren’t quite sure what CNC turning entails.

That’s why we’ve put together this short guide explaining the basics of what it means and the process it involves.

What is CNC Turning?

What does CNC stand for?

Firstly, let us start by defining ‘CNC’. CNC stands for Computer Numerical Control. This refers to a manufacturing process that is led by a computer program. CNC works in conjunction with CAD (Computer Aided Design), which is what designs the component that CNC machines then make, sending over a code that tells these machines exactly what they need to do, rather than being controlled by a person.

The Turning Process

As for the turning process, this involves bars of raw material being held in place and rotated at a high speed. At the same time, a static cutting tool comes into contact with it in order to shave away at the material along its length and with varying depths in order to create a desired shape.

This is unlike other cutting processes, whereby the cutting tools themselves rotate in order to cut into the material.

So how does this work with CNC? CNC turning, then, works by a code being created and sent to the CNC turning machine, telling it where and how deep it needs to cut into a material in order to accurately create a specific shape.

Metal Fabrication

CNC turning services are commonly used for bespoke metal fabrication. Due to its precision, it makes for a great method to create metal components that need to be uniform in shape and size, such as nuts, bolts, screws and car parts. All of these can be made to a high production volume without compromising on symmetry.

Typically, CNC turning is used to create smaller metal parts, whilst CNC milling would be used for larger metal components.

Various ferrous and non-ferrous metals can be used in the process of creating things with CNC turning, such as aluminium, steel, titanium, copper and more. A wide variety of finishes can also be applied to CNC made components, including paints, powder coatings and metal coatings (such as zinc).
