How Does a CNC Machine Work? Your Questions, Answered

Do you have the itch to create? Do you love the idea of taking a design and turning it into reality?

If so, then we’ve got the perfect machine for you: a CNC machine.

CNC machines are the premier tool in the manufacturing industry to turn complicated, intricate designs into tangible reality. Different types of CNC machines exist to suit your different creative needs.

If you’re curious about the answers to the questions of what is a CNC machine and how does a CNC machine work, you’re in the right place. In this article, we’ll answer those questions and more.

What is a CNC Machine and How Does a CNC Machine Work?

CNC stands for Computer Numerical Control.

To understand how this plays into machining, you’re going to have to think back to your elementary mathematics days. Do you remember studying the x-y-z coordinate system?

Using this coordinate system, the position of any point in space can be defined. When you have all three coordinate points, you know how far to the right or left it is, how high it is, and how far back it is from your particular vantage point (known as the origin).

A CNC machine uses a computer-drawn file of a design to change the design into thousands and thousands of little points on the coordinate system. Depending on the precision of the CNC machine, these points could have an accuracy up to the thousandths of a millimeter!

With these points, a CNC machine uses a router to cut away material from a block of material until the final design is outputted. The good thing about CNC machine functions is that they can apply to a variety of different materials.

Need to create an intricate piece of wooden furniture? A CNC can help.

Want to manufacture a complex steel beam? A CNC can help here as well.

How Can I Get a CNC Machine?

Now that you know what a CNC machine is and how it works, you’re probably interested in how you can get one.

The first thing you should know is that new CNC machines are expensive. There’s no two ways about it. To get this kind of premium design functionality, you’re going to be looking at a hefty price tag for a new machine.

However, there is another option: looking at used CNC machines for sale. On the used market, CNC machines are much more affordable. The good thing is, just because these machines are used doesn’t mean that their functionality is compromised.

On the other hand, these machines are built to last. As long as the machine was kept in good condition, you should be able to rely on a used machine to work just as well as a new one.
