What is CNC Machining?

Computer Numerical Control (CNC) machining is a process whereby computerised controls are used to machine parts from solid billet into final components.

A range of tooling can be utilised via dedicated programs to ensure that intricate shapes and chamfers can be achieved during the CNC machining process.

Not only can CNC machining be performed on a wide range of materials including stainless steel, inconel, titanium and aluminium, CNC machines are also capable of achieving very tight tolerances.

At GoodFabs, we offer CNC machining services via our CNC mills and lathes on which we produce a whole host of components from basic v-band rings to thin wall tailpipe sections for F1 race teams.

While we could fabricate some of these items, CNC machining enables us to achieve the tight tolerances required whilst boasting the ability to vary the wall thickness within the part itself for example.

The CNC Machining Process

Much of our CNC machining starts with the production and utilisation of a CAD model. These are used to identify the various shapes and requirements for the part to be machined after which our experienced team will create a specific program which will be read by the CNC machine.

As well as specifying the final design of the part, the program will also assign tooling to individual elements of the design to ensure the final part matches as closely as possible the design and desired tolerances.

Parts are held in vices or ‘jaws’ during the CNC machining process on a bed which can tilt and move as required to accommodate the design requirements of the piece. During the machining process a liquid coolant is continually applied to ensure the tools do not overheat and break causing damage not only to the specialist equipment used, but also to the piece itself.

We provide a variety of CNC machining services including CNC milling and CNC turning. If you have a project you would like to discuss, simply contact us today.
