What Parts Consist of A CNC Machine?

Before introducing the parts of the CNC machine, let’s first repeat what is CNC machining.

What is CNC Machining

CNC machining is a term commonly used in manufacturing and industrial applications. But exactly what is CNC? And what is a CNC machine?

The term CNC stands for ‘computer numerical control’, and the CNC machining definition is that it is a subtractive manufacturing process that typically employs computerized controls and machine tools to remove layers of material from a stock piece, known as the blank or workpiece, and produces a custom-designed CNC machined part.

This process is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and finds application in a variety of industries, such as large CNC machining, CNC machining parts and prototypes for telecommunications, and CNC machining aerospace parts, which require tighter tolerances than other industries. Note there is a difference between the CNC machining definition and the CNC machine definition one is a process and the other is a machine. A CNC machine is a programmable machine that is capable of autonomously performing the operations of CNC machining.

Subtractive manufacturing processes, such as CNC machining, are often presented in contrast to additive manufacturing processes, such as 3D printing, or formative manufacturing processes, such as liquid injection molding. While subtractive processes remove layers of material from the workpiece to produce custom shapes and designs, additive processes assemble layers of material to produce the desired form and formative processes deform and displace stock material into the desired shape. The automated nature of CNC machining enables the production of high precision and high accuracy, simple parts, and cost-effectiveness when fulfilling one-off and medium-volume production runs. However, while CNC machining demonstrates certain advantages over other manufacturing processes, the degree of complexity and intricacy attainable for part design and the cost-effectiveness of producing complex parts is limited.

While each type of manufacturing process has its advantages and disadvantages, this article focuses on the CNC machining process, outlining the basics of the process, and the various components and tooling of the CNC machine (sometimes incorrectly known as a C and C machine). Additionally, this article explores various mechanical CNC machining operations and presents alternatives to the CNC machining process.

YIJIN Hardware Custom CNC Machining Parts

It is not difficult for us to see from this paper What is CNC Machining and What parts of CNC machines are simply introduced. Now let’s take a look at the pictures of some main parts of the CNC machine.

CNC Lathe Bed

The tool turret travel over the cnc lathe bed, which is specially hardened so any kind of machining can’t affect them.


CNC lathe machine chuck grips the component which is to be machined. Chuck itself has many parts. Jaws are mounted on the chuck to grip the machined parts.


The headstock of a cnc lathe machine has the main motor of the cnc lathe machine which drives the main spindle. Chuck is mounted on this main spindle.


The tailstock is mostly used to give an extra gripping force for component machining. For long components machining, they provide an extra force on the other end so the machining process can complete smoothly. You can see in the above picture at the one end chuck is gripping the component and on the other end, the tailstock is providing the extra force.

Tailstock Quill

Actually, you move the whole tailstock forward or reverse, but in that way, it is not used to grip the part, but the tailstock is traveled to a point near the component and then it is set there, you actuate the tailstock quill which travels either with hydraulic pressure or pneumatic pressure to grip the component.

Foot Switch or Foot Pedals

Footswitches are used to actual the chuck and tailstock quill. Through these pedals, cnc machinists open and close the chuck to grip the component, the same way the tailstock quill is taken to a forward position or reversed through these pedals.

CNC Control Panel

The brain of the cnc machine, and all the cnc programs are stored inside this panel, cnc machinists control the whole machine through the keys on this panel. CNC machinists start/stop the machine move axis by pressing different keys on this panel.

They can enter a new program by using this panel, programs can be transferred by using the USB port on this panel as well. So this is the main part that controls the whole cnc machine.

Tool Turret

The tool is mounted on the tool turret which is used for component machining. Tool turrets vary in shape and the number of tools that can be mounted on them.


This article mainly tells the story of what is what are the parts of CNC machine tools and CNC machine tools and their physical figure, Yijin solution you can see here very happy, if you like this article, I hope you can share this article with the people around you, if you want to buy the product, you can send mail, send to us your specific needs, We’d be happy to give you a realistic quotation, thank you
