We are all familiar with old milling machines, and we know what their capacity is. But today, the addition of a computer numerical control system or CNC has caused their efficiency to increase significantly, and the machine is used for accurate and quality cuts. CNC milling machine is a type of milling machine intelligently designed for the machining process under computer programs.
Given that at SOZN, we strive to provide advanced and different services using the CNC milling machine, in this article, we intend to explain to you important and vital information about them.

What is CNC milling?
A CNC milling machine is a machining and milling machine controlled by computer programs, and human resources involvement is minimized. Due to their inherent properties, these machines are used to cut and machine many materials and perform parts’ production processes from zero to the end. The exciting thing about applying CNC milling services is that the position taken out of them is ready to be sent to the market without assembly.
How does a CNC mailing machine work?
When you are looking to work with CNC milling machines, you need to prepare the engine both for hardware and software. The operation of these devices can be summarized in the following four steps:
- Design a CAD model
- Convert CAD model to a CNC program
- Launch of CNC milling machine
- Execution of milling operations
This machine’s milling process is done by creating a two-dimensional or three-dimensional design with AutoCAD software’s help. The prepared system must be converted to a file format compatible with the CNC machine, the layout of which is G-Code. In the next step, by turning on the machine motor, you can perform the cutting and milling process and finally receive the workpiece.
What are the main CNC milling parts?
There are several ways to get acquainted with the CNC milling machine that anyone can choose according to their circumstances, but knowing the CNC milling parts is a perfect and appropriate solution. When you get acquainted with the milling machine’s different features, you see its working procedure and its result.
Machine interface: The machine interface refers to the part of the CNC milling parts with which the operator is in direct contact, during which it is possible to plan the work of the machine and how to execute it. This page may be touch or buttoned. But next to it, there is a screen so that the operator can enter the milling coordinates and movement specifications with buttons.
Column: this part is one of the machine’s support and structural components responsible for maintaining and supporting all CNC milling parts. This part consists of a fixed base to which different parts of the device are connected. The column is responsible for assisting the milling process and maintaining the cooling systems and the oil tank. Depending on the horizontal and vertical CNC milling machine, the machine column’s design is variable, and it is possible to use different patterns for it.
Knee: It is a movable and adjustable part attached to the machine’s column, and its function is to support the saddle of the device and the table of the CNC milling machine. This part of the machine can be adjusted along the Z-axis, and the operator can use it to change the height of the machine table for three-dimensional cuts. This tool may adjust the size and pressure of the threads and has different designs on different devices.
Saddle: The part is said to be mounted above the Knee and acts as a support for the desk. This part of the CNC milling parts can move parallel to the axis of rotation and therefore prepare the working conditions so that it is possible to adjust the work sample horizontally. Thus, the saddle and elbow’s simultaneous operation in these devices causes movement in different dimensions to make more complex cuts.
Worktable: Refers to the part of the CNC milling machine mounted on top of the saddle and is responsible for holding the workpiece or holding device. Depending on the device used, this part can be adjusted horizontally and vertically or in combination.
Most of this piece’s work is a function of the movement of its two lower parts, namely saddle and Knee. Of course, their design and dimensions vary according to the size of the CNC milling machine, and you can make changes to the size of the table according to its efficiency.
Arbor: It is one of the parts used on the machine’s shaft, placed inside the spindle in horizontal milling machines, and provides the installation conditions for various machining tools. This piece is used in different dimensions and diameters, mostly changed according to the milling machine type.
Ram: Refers to one of the CNC milling parts that are commonly used in vertical machines, and its location is fixed on top of the column. This tool acts as a spindle holder and support. Due to the milling process changes, it is possible to change the RAM position in terms of length and movement conditions.
Spindle: One of the CNC milling parts is attached to the machine’s column responsible for holding the arbor. The spindle is responsible for regulating the machine’s speed and acts as a bridge between the electric motor and the cutting tool. The spindle’s location in the vertical CNC milling machine and the horizontal CNC mill is different. Still, there is not much difference between them in terms of efficiency.
Machine tool: It is a machine held by a spindle and used to cut and remove part of the material. Different milling tools are used for these machines, which may be used for flooring or simply cutting horizontally or vertically or even angular cutting. For this reason, the choice of milling tool depends on other factors such as the material of the workpiece as well as the geometric conditions of the cut. But in general, these tools have a high ability to cut different materials with different physical and chemical conditions.
Benefits of CNC milling service
The benefits of CNC milling service are enormous. When a tool path is created, and a device is programmed, a section can be run 1 or 100,000 times. CNC machines are built for precision and reproducibility, which makes them cost-effective and efficient. CNC machines can also work with raw materials from aluminum and base plastics to exotic materials such as titanium, making it an ideal device for almost any job.
SOZN Group hopes that the information provided about CNC milling parts can resolve your ambiguities in working with this machine and, on the other hand, help you in purchasing the device. But if you are still unsure, contact SOZN for more information. This company supports 3-axis, 4-axis, 5-axis milling, and right angle milling capabilities to rapidly create designs from simple straight lines to complex geometric shapes.
