CNC Turning Process

What is CNC Turning

CNC turning, also known as computer numerical control turning, is a subtractive machining technique that involves a cutting device being set against a rotating piece to remove material. It is typically done using a CNC Lathe, also known as a turning center that cut the material, which includes metal, wood, and even plastic.

Overview of CNC Turning Process

The CNC turning process, like most other traditional mechanical CNC machining processes, employs computerized controls to operate and manipulate machine tools that cut and shape stock material. Furthermore, the process follows the same basic production stages as all CNC machining processes, which include:

  • Creating a CAD model
  • Creating a CNC program from the CAD model
  • Configuring the CNC lathes
  • Carrying out the turning operation

In the CNC turning, workpieces is held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. The difference between CNC turning and manual lathe turning is that the CNC machine is automated and can produce complex contours in one operation, eliminating additional set-ups.

CNC Turning Materials

CNC turning can be done on any material that is hard enough to produce chips when cut. The shorter the chips produced by a material, the easier it is to cut and remove chips from the work area. If a chip does not break off the workpiece quickly, it will create a wire that will likely wrap around the tool or spindle, reducing cutting power. Material that is too soft will smear rather than produce chips, and it will also interfere with the cutter.

Benefits of CNC Turning

CNC turning machines are quick and precise, allowing for the efficient production of complex and specialized products. CNC turning has lots of advantages, including:

Cost Savings

CNC turning requires less labor than traditional manual machining methods because it is a largely automated process. This minimizes the need for workers to monitor machines for long periods of time and reduces the risk of injuries associated with manual machining techniques. Every business seeks ways to reduce costs while maintaining quality. Businesses can improve their bottom line by utilizing CNC lathes, which provide significant cost savings. CNC lathes enable the efficient production of complex and specialized products because they work faster and more accurately.


When CNC machinery is used, safety is greatly improved. Because there is no bending or crouching required to operate the machines, ergonomic conditions for workers are greatly improved. This results in fewer workplace accidents and less fatigue, reducing the risk of human error in the turning process significantly.


CNC turning has made a significant impact on production speeds. With CNC machines, manufacturers can produce more parts in less time than they could with previous methods. The increased efficiency of CNC turning also means that manufacturers can reduce manpower needs and other costs while boosting productivity. In addition, automatic tool changes increase accuracy and reduce waste generated by human error in changing tools manually.


CNC machines have a high level of accuracy (within 0.0015″). Once a program is written, each part will come out exactly the same as the last one. The process can also be repeated with 100% consistency as many times as required.

CNC turning is ideal for producing cylindrical parts that require exceptional concentricity and precision.
