It is no secret that CNC turning has been the cornerstone of the manufacturing industry for decades. And there are good reasons for this. This machining process is used to create high-precision parts because it’s accurate, efficient, and economical. In today’s blog post, we will explain the workings of CNC turning in greater detail. If you wish to learn more about CNC turning, this blog post is for you.

What Is CNC Turning?

CNC turning is a subtractive machining process that involves rotating a workpiece around a stationary cutting tool. The workpiece is held in a chuck and spun at a high speed around a non-rotating cutting tool, which removes material from the piece to give it the desired shape. This machining process is computer-controlled, ensuring the production of intricate components.


Advantages of CNC Turning

High level of precision and accuracy

It is one of the aspects that makes precision CNC turning the go-to subtractive machine process. As computer-controlled machines, CNC turning machines can create precise, consistent cuts. The CNC precision-turned parts produced are identical. 

Efficiency in mass production

Precision CNC turning allows for producing CNC precision-turned parts in bulk quantities. Since the process is computer-controlled, it is capable of making large quantities of CNC precision-turned parts while maintaining top quality.


CNC turning is a flexible machining process that produces a wide range of complex CNC-turned parts, including cylinders, cones, spheres, and many more. Since CNC machines are preprogrammed, operators can adjust as needed.

Cost-effective compared to manual machining

Hiring people to perform manual machining is far more expensive than using CNC turning machines. While the initial investment in CNC turning machines might be higher than manual equipment, the long-term cost savings are worth it.


What Is the Difference Between CNC Turning and CNC Milling?

CNC turning and CNC milling may be confusing to people who are not familiar with these two processes. We will help you understand the differences between CNC turning and CNC milling. 

Workpiece motion

The primary distinguishing factor between CNC turning vs. CNC milling is the workpiece motion. The CNC turning process is directly the opposite of CNC milling. In CNC turning, the workpiece rotates against a stationary cutting tool to remove the material. In CNC milling, on the other hand, the workpiece is held stationary while multi-point cutting tools move along the axes to remove material. In other words, the CNC milling machine moves the cutting tool around the workpiece.

Cutting tool

Another aspect that differentiates CNC turning from CNC milling is the tooling. In precision CNC turning, a single-point cutting tool is used to remove material from a rotating workpiece. CNC milling, on the other hand, uses multi-point cutting tools such as end mills, drills, and ball-nose cutters to cut the workpiece. 


CNC turning works best for creating parts with rotational symmetry. These include cones, cylinders, and spheres. CNC milling is preferred for producing intricate 3D geometries. 


When Should I Choose CNC Turning?

Rotational symmetry

As mentioned, CNC turning is best suited for producing cylindrical and oblong-shaped components. If you want to create CNC-turned parts that take on rotationally symmetrical forms, CNC-turning is the way to go.

High precision and repeatability

The CNC turning process is computerized and highly monitored to produce high-precision parts. That is why it is the go-to process for manufacturers looking to create precision-turned parts that demand consistent accuracy.

Large quantities

CNC turning is preferred for manufacturers who are looking to produce identical CNC turned parts in large quantities. The process is automated and can churn out hundreds and hundreds of CNC precision-turned parts 24/7. 

Specific materials

Choose CNC turning if your goal is to produce machinable parts that take on cylindrical forms. 

Cost-Effectiveness for One-off Prototypes, Small & Large Batches

CNC machining is a cost-effective manufacturing process for producing one-off prototypes, small and large series. The initial investment for CNC machining suppliers might be high, but the reduced labor requirements, minimal waste, and speed will save them money in the long run. For clients who need small-series prototypes and one-off parts, CNC machining is a more cost-effective option than other processes that require molds.

1. What Types Of Parts Can Be Made With CNC Turning?

CNC turning is best suited for creating parts with rotational symmetry. Examples of such parts include cones, spheres, and cylinders.

2. What Are The Advantages Of CNC Turning Compared To Traditional Machining?

Unlike traditional machining, CNC turning produces high-precision parts because the entire process is computer-controlled. Moreover, the process is economical and suitable for one-off prototypes.

3. How Is CNC Turning Different From CNC Milling?

The main difference between these two processes lies in the movement of the workpiece. In CNC turning, the workpiece does not move. Instead, it is held in a chuck and rotated against a stationary cutting tool. CNC milling, on the other hand, involves rotating cutting tools around the workpiece, which is stationary.

4. When Is CNC Turning The Most Cost-Effective Option?

CNC turning is cost-effective when it comes to the production of symmetrical parts in any quantity. The main factors contributing to its cost-effectiveness include its speed and minimal waste. The CNC machining suppliers bear the high initial investment in the machine. So the cost per part becomes low for customers whether the quantity is small or big.

5. What Are The Limitations Of CNC Turning?

CNC turning is preferred for creating parts with rotational symmetry, meaning it is unsuitable for complex geometries. CNC milling is recommended for building parts with complex geometries and features.
