These machines are programmed to accurately and precisely cut and shape various materials, including metals, plastics, and wood. In this article, we will discuss everything you need to know about CNC turning.
What is CNC Turning?
CNC turning is a machining process in which a cutting tool, typically a non-rotary tool bit, is fed into a rotating workpiece. The cutting tool is moved along the axis of the workpiece to produce cylindrical parts with precise dimensions. CNC turning is often used to create parts for the automotive, aerospace, and medical industries, among others. This process can be used with a variety of materials, including metals, plastics, and wood. The CNC turning process is performed by a computer-controlled machine tool called a lathe, which can be programmed to produce complex parts with high precision and accuracy. Overall, CNC turning is a versatile and efficient manufacturing process that is widely used in modern industry.
How Does CNC Turning Work?
CNC turning is a subtractive manufacturing process that uses a computer-controlled lathe to cut and shape materials into cylindrical parts. The process involves a cutting tool being fed into a rotating workpiece, which is then moved along the axis of the workpiece to produce parts with precise dimensions.
The CNC turning process begins with a design, which is created using computer-aided design (CAD) software. The design is then converted into a code that the CNC machine can understand, called G-code. This code is loaded into the CNC machine, which controls the movement of the cutting tool and the rotation of the workpiece.
Once the CNC machine is set up and the code is loaded, the cutting tool is brought into contact with the workpiece. The tool is then moved along the axis of the workpiece, removing material and creating the desired shape. The machine may also use coolant to help keep the cutting tool and workpiece cool during the cutting process.
The CNC machine can be programmed to make a variety of cuts, including facing, turning, drilling, and boring. This allows for the creation of complex shapes and designs with high precision and accuracy. The machine can also be programmed to make multiple cuts in a single operation, reducing the time and cost required to produce a part.
CNC turning is used in many industries to create parts out of various materials, including metals, plastics, and wood. The process is especially useful for creating parts with complex shapes or tight tolerances, as it allows for high precision and accuracy. Overall, CNC turning is an efficient and versatile manufacturing process that has become increasingly popular in modern industry.

For example, materials that are prone to chipping or cracking, such as ceramics or glass, may be difficult to machine without causing damage to the part or the machine.
Cost
CNC turning can be an expensive manufacturing process, particularly for small production runs. The cost of the machine, tooling, and programming can be significant, and may not be justifiable for small-scale production.
Tool Wear
CNC turning involves the use of cutting tools, which can wear down over time. Tool wear can lead to a decrease in precision and accuracy, as well as an increase in the time and cost required to produce parts.
Surface Finish
CNC turning can produce parts with a high degree of precision and accuracy, but the surface finish may not be as smooth as other machining methods. Parts may require additional finishing processes, such as sanding or polishing, to achieve the desired surface finish.
