What Is CNC?

For the uninitiated, CNC stands for Computer Numeric Control and refers to the automation of machine tools using computer programmed commands, as opposed to manually operated machinery that uses wheels and levers.

The first “NC” machines were built as early as the 1940s and adapted existing tools to incorporate motors that moved the controls automatically using ‘punch cards’ as code. Soon after, these mechanisms were updated with digital computers and code, creating the modern CNC machines that are revolutionising machining processes today.

Today, CNC is synonymous with CNC Milling Machines and CNC lathes. CNC milling uses  automated multiple axis machines powered by motors and driven by code that can perfectly replicate digital drawings and computer aided design (CAD). CNC devices are much faster and much more accurate than manual milling machines, with the ability to perfectly repeat movements, change tools in seconds (or less, if your equipment is as advanced as MRT’s) and produce complex shapes easily.

The result is identical components that are guaranteed to fit every time.

We specialise in using CNC as a process to finish castings, where tight tolerances or finish is required. The process is much faster and less wasteful than CNC machining solid billet material and provides a much higher quality finish than casting alone.

The marriage of casting and CNC machining  means we can produce components to a tolerance of microns as with purely machined parts, but with the economy and speed of casting the initial form. We can be relied upon by our clients to produce components for medical, military and aviation devices confident in the knowledge that they will exceed expectation.
