So, what is a CNC machine used for?

A CNC machine is a versatile piece of equipment that can be used by DIY hobbyists and large industrial operations alike. In a nutshell, it’s an automated machining technique that can cut a wide range of materials to produce a finished product. 

But there’s much more to it than that. Here’s a primer on CNC machine working, together with a look at five rather surprising CNC machine uses. 

What Is a CNC Machine Used For? CNC Basics

Let’s start at the beginning: what does a CNC machine do? 

CNC stands for “computer numerical control,” and is a reference to the autonomous, computerized nature of the machine. A CNC machine is rather like the opposite of a 3D printer, because it is a “subtractive” rather than an “additive” manufacturing process. 

In other words, whereas a 3D printer builds an object by adding layers, a CNC machine creates by subtracting material from a blank, in much the same way that a sculptor produces a sculpture.

There are a number of advantages to using CNC machines. Primarily, they can be used with a wide range of materials, including plastics, wood, metals of different kinds, glass, wax, composites, and much else. 

CNC techniques are also great for home or hobby projects. Check out used CNC machines for sale to get an idea of what you can use. 

5 Surprising Uses for CNC Machines

So much for what CNC machines do. Now let’s take a look at some of their more interesting applications: 

1. Prototyping

As with 3D printers, one of the more widespread uses of CNC machines is for 3D modeling and prototyping. 

CNC techniques are perfect for crafting realistic prototypes, a crucial part of the design process. It’s also possible to scan or copy objects and model them with a CNC machine in order to create innovative designs. 

2. Furniture Making

Believe it or not, CNC machines are excellent at cabinetry and furniture making

In fact, these machines have remarkable carpentry skills. They can craft cabinets, tables, chairs, countertops, doors, and just about anything else with fantastic precision. 

3. Signs

CNC machines are especially popular when it comes to sign-making. 

The beauty of CNC machine working is that it is effective in a number of different materials and media. So it’s easy and cost-efficient to use them to produce professional-looking signage for any business. 

4. Musical Instruments

Yes, this is certainly surprising. 

But it’s true that CNC machines are used to manufacture superior musical instruments. The precision computer programs used for CNC machining can cut materials to exact specifications to produce beautiful tonal ranges. 

5. Metal Machining

Another interesting use for CNC machines is their ability to work with metals like brass and aluminum. It’s necessary to step up the machine’s cutting power and invest extra time to prepare, but the result is well worth the effort.
