CNC machining processes mainly include CNC drilling, CNC turning and CNC milling. All these processes differ from each other and have their own uses as well as applications.
Factories are constantly in search of novel CNC technologies that can be employed to increase the pace of production while reducing costs.
At the end of this write-up, you will have a complete understanding of the CNC machining process, CNC turning, as well as its applications on the basis of different factors.
What Is CNC Machining?
A manufacturing procedure in which already programmed computer software guides the direction of manufacturer equipment and machinery is called CNC (Computer Numerical Control) machining.
The procedure can be employed to regulate a span of complex machinery.
Three-dimensional cutting work can be handily achieved with the utilization of CNC machining in one set of prompts.
Computer Numerical Control machines (CNC machines) enhance the various production procedures.
Such machine devices get all the work done manually. For example, shaping and processing materials.
CNC Machining Processes
CNC is actually a developing process where computer software that is already programmed commands the factory machinery and tools’ movement.
Following are the common CNC machining processes.
- CNC turning process
- CNC milling process
- CNC drilling process
- CNC Grinding Process
- CNC Sawing Process
- CNC Finishing Process
CNC Turning Process
It is a process in which the rotating cutting equipment cuts the material. CNC turning is also called subtraction machining because, in this process, you get the desired shape through material removal
Steps Of CNC Turning
This process has four main steps.
Step 1
Adding and loading the basic material in the machine.
Step 2
Cutting the material according to the required design and pre-set data.
Step 3
Cut-out parts of material move towards the post-processing like assembly and welding, left behind the CNC turning.
Step 4
Extraction of the finished product through some methods such as splitting or sawing.

8 Main Advantages Of CNC Turning
CNC turning has high demand due to the benefits it offers, such as;
- It produces products with high tolerances.
- It is also used for including exact rotational features in a product that has already b
- een made with the help of another method.
- The parts used to be machined from various materials like plastic and metal CNC turning.
- It provides rapid market testing and prototyping.
- It makes sure the quality finishes of any part.
- It is adaptable to a large number of materials.
- Its accuracy and precision rate are much higher as compared to other machining processes.
- It works perfectly even for the production of large volumes.
Is CNC Turning Right For My Project?
CNC turning is a great option for your project if you have a bar stock with axial symmetry. CNC turning works greatly on parts that have large dimensions.
Thus, it will provide you the best quality and exact end products.
If your project is to make intricate components, turning is completely perfect for your project.

Common CNC Turning Applications
CNC turning is widely used in molds, making toys, furniture and prototypes. It is used primarily for manufacturing highly precise metal parts, mainly for engineering plans. Furthermore, it creates cylindrical surfaces perfectly.
CNC Milling Process
CNC milling is also a CNC machining process in which a computer is used to control a machine that molds shapes into plastics, metals, and other substances.
Furthermore, CNC milling processes have a powerful resemblance with drill presses and computer-controlled routers.
5 Top Advantages Of CNC Milling
The most common advantages of CNC milling are given below.
- It has a high rate of removing the metal.
- CNC milling a circular cutter.
- CNC milling is cost-effective as compared to other CNC machining processes.
- It takes less time to divide the material into pieces.
- It is used for a wide range of milling tasks.
Is CNC Milling Right For My Project?
If your project involves parts that are not cylindrical, round, or conical, CNC milling is best for your project. As CNC milling applications are discussed above, you should use CNC milling if your project involves any of those applications.
In some cases, both CNC milling and CNC turning can be used one after another for the manufacturing of a product.
