What is a CNC mill and how does it work?

CNC stands for Computer Numerically Controlled, and it’s a process that is controlled by a computer. The computer is programmed with a series of commands that tell it what to do and when. CNC machinery is generally used to cut and shape a range of materials.

The most commonly used programming language, which is understood by all machines, is G code. However, manufacturers often prepare their own proprietary language. This is often easier to use and understand, but it is still converted to G code for use by the machine itself.

How does this apply to a milling machine, and how exactly does it work? Let’s take a look!

What is CNC milling?

Milling is a process through which raw materials are cut using a drill-like tool. This tool can operate in both the x and y axis to produce either finished items or the pieces to create finished items. CNC milling is simply this same process but controlled by a pre-programmed computer.

Although many types of materials can be cut using CNC milling with a variety of different tools, they are most commonly used to cut metals. They are extremely efficient at cutting both precision and complex parts. While there are some off-the-shelf machines available, CNC milling can also be customised to suit specific business requirements.

What are its benefits to an employer?

One of the main benefits to an employer of choosing a CNC mill is that it takes the manual strain out of the process, making the workplace much safer and reducing the number of injuries and accidents that operators endure. Musculoskeletal injuries to the back and neck are one of the most common types of injury associated with repetitive and manual processes, and according to the the Office for National Statistics, over 30 million days were lost in a single year from this type of injury alone.

Another key benefit of using a CNC milling process is the precision it affords you. This, in turn, cuts down on waste and reduces your costs. This reduction in costs can be crucial in allowing your business to remain competitive and even win new business.
