What Is CNC Precision Machining?

What if you could use cutting-edge technology to build almost any components you need for industries, like aerospace and medical parts?

With precision CNC machining, you can do just that. Unfortunately, most people don’t know what precision machining is or how it works, and that means they can’t benefit from this game-changing technology.

What Is CNC Precision Machining?

CNC precision machining is a very specific machining process that helps you manufacture the parts you need using computer-controlled machine tools. Traditionally, this process is conducted by skilled machinist operators, but some companies rely on robots to use this process to manufacture parts at high speed.

Ultimately, precision machining boils down to two key aspects. To begin, you’ll need to use the right cutting tools (the more advanced, the better) to remove the material as needed; this allows you to perfectly match the dimensions of the part that your project requires. Next, you’ll need a CNC (or Computer Numerical Control) machine to control the cutting tool as it works.

Understanding the Precision Machining Process

No matter how big or small the project, precision machining always consists of five steps.

The first step is using CAD (Computer Aided Design) software to design the part you wish to create. The second step is to convert the CAD design to CAM (Computer Aided Manufacturing) so that the CNC machine will be able to understand the design.

The third step is to set the CNC machine up, which involves calibrating the machine, mounting the workpiece, and ensuring that the clamps are tight, and that the coolant is at appropriate levels. The fourth step is to execute the process and let the CNC machine do its work.

The fifth and final step is to inspect the finished part to discover if it is fine “as is” or if it will need any further work (such as polishing or grinding). The good news is that with the right tools (like those available from DATRON), you’ll rarely have to do any additional work on the part.

Types of CNC Precision Machining Equipment

There are many different types of CNC precision machining equipment, allowing you to find the perfect tools to suit your specific needs. This includes milling equipment that uses specialized rotary cutters to remove the excess material from the piece you are working on. Keep in mind there are many kinds of mills, including chamfer mills, end mills, and helical mills.

You’ll also need to utilize CNC turning equipment. This equipment rotates the piece you are working on alongside a rotating cutting tool. Chances are you are familiar with some of the more common turning equipment, including lathes, threads, and external grooves.

Finally, you’ll need CNC drilling equipment to facilitate your precision machining needs. This equipment uses rotating multi-point drill bits to create cylindrical holes in the various workpieces you are working on.

Types of CNC Precision Machining Tools


One reason CNC precision machining is so fulfilling is that it allows you to work with many specialized tools. This includes spot drills that are used to make small starting points that you will further work on using a twist drill. Another important tool is the end mill, which you can use to remove excess material in a quick and orderly fashion.

Face mills are precision tools that help you make flat sections of material before you carry out your cutting. Speaking of precision tools, you can use reamers to expand existing holes in the workpiece while maintaining the tight tolerances your project requires.

Depending on your needs, other specialized tools are available. This includes hollow mills, gear cutters, fly cutters, and thread mills. When in doubt, we recommend you contact us with questions about which tool is best for which job.

Precision CNC Machining Applications

While CNC machining has a number of potential applications, it is used primarily in three industries. This includes the automotive industry, the medical industry, and the aerospace industry.

At a glance, those are very different industries, so why do they all rely very heavily on CNC precision machining? In short, each industry requires specialized parts that require tight tolerances due to safety regulations. With precision machining, you can repeat the machining process very easily (good for larger-scale operations), and you can rest assured everything will be as tight and safe as it needs to be.

Advantages of Precision CNC Machining

Still on the fence about whether you need to use CNC machining for your purposes? That may change when you understand the many benefits this process has to offer.

First, this process is more accurate due to the computer at the heart of it, and the parts you create will be clean and free of defects. Second, it speeds production up at every stage of the process: by running machines up to 24 hours a day, you can meet your production needs in no time, and you can then use manual assembly lines to further speed things up.

Third, CNC machines can help reduce your overall costs, which is great for your bottom line. Throw in the fact that they reduce your energy consumption and keep your employees safe, and there are plenty of reasons to start precision machining today!
