What Is A CNC Router And What Does It Do?

CNC routers are revolutionizing the way countless individuals and industries bring their works of art to life, optimizing efficiency far beyond what was once thought possible. But what exactly is a CNC router? To help you comprehend its inner workings, here’s an overview of how these powerful machines operate.


CNC routers are state-of-the-art machines that can effortlessly cut through a variety of materials like aluminum, wood, plastic and foam. Instead of relying on human operators to control the process, computer numerical control (CNC) software enables these cutting edge devices to do all the hard work for you!

CNC machines are efficient tools used in manufacturing, as they feature the capability to cut along three axes—the X-axis (front and back), Y-axis (left and right) and Z-axis (up and down). Due to their automated nature, CNC routers can produce complex components faster than a human operator ever could with impressive precision.


Cutting Bed

The CNC’s flat surface, otherwise known as the cutting bed, is where users have to place their materials before beginning work. To ensure that these materials remain in place during operation, operators must employ screws or adhesives for securement around the bed’s perimeter. Alternatively, T-slot decks can be bolted down with clamps and bolts while vacuum suction mechanisms are available on a wide range of CNC tools. No matter which method you choose though – they will all guarantee your material stays put!


To make the cuts, this component is situated at the end of a robotic framework. Its spindle rotates its cutting bit with an adjustable rpm based on what material it’s cutting; softer materials need faster revs while harder materials require slower speeds. With these variable revolutions per minute, precision and accuracy are assured!

CNC Computer

The CNC machine runs through an interdependent system of a computer, controller, and drive systems. By using CAD software to create designs that are then transformed into g-code via a post processor, the user communicates these instructions to the CNC controller which in turn utilizes them to direct its functions. Through this collaboration between components, complex materials can be fabricated with remarkable precision!

Drive Systems

Drive systems encompass the parts that allow the router to move along each of the three axes, and therefore, there is one for each direction. A single drive system consists of a motor, a bearing or guiding system along which the router moves, and a means of moving. Typically, it can move due to a mechanism consisting of a ball or lead screw system or a rack and pinion setup.

Why invest in a CNC preventative maintenance program? It’s simple, a lack of lubrication or unresolved backlash can turn a small issue into huge one. You likely already know that CNC or industrial machine issues can cost your company a lot of money. Luckily, most of these issues can be avoided with proper and regular maintenance.
