What Is 4 Axis CNC Machining?
In the world of precision parts machining and customization, CNC (Computer Numerical Control) machining is a cornerstone technology. Among the various types of CNC machining, 4 axis CNC machining holds a significant place. Let’s explore what 4 axis CNC machining is and how it relates to the services offered by GreatLight CNC Machining Factory.

Understanding 4 Axis CNC Machining
CNC machining uses computer – controlled machines to shape materials into precise parts. Traditional 3 axis CNC machining operates along the X, Y, and Z axes. In contrast, 4 axis CNC machining adds an additional rotational axis. This extra axis allows for more complex and intricate part geometries to be machined.
The fourth axis is typically a rotational axis, often referred to as the A, B, or C axis. For example, if the X, Y, and Z axes control linear movement in the horizontal, vertical, and depth directions respectively, the fourth axis can rotate the workpiece around one of these linear axes. This rotation enables the machine to access different sides of the workpiece without the need for manual re – positioning, which is a major advantage over 3 axis machining.
Advantages of 4 Axis CNC Machining
Enhanced Complexity: With the ability to rotate the workpiece, 4 axis CNC machining can produce parts with undercuts, angled holes, and complex curved surfaces that would be difficult or impossible to achieve with 3 axis machining. For instance, in the aerospace industry, components with complex geometries are often required, and 4 axis machining can create these parts with high precision.
Improved Efficiency: Since the workpiece can be rotated during machining, multiple sides of the part can be machined in a single setup. This reduces the time spent on re – positioning the workpiece, which in turn increases the overall production efficiency.
Higher Precision: By minimizing the need for manual re – positioning, 4 axis CNC machining reduces the potential for errors that can occur during the re – clamping process. This results in higher precision and better surface finish of the machined parts.

Additionally, GreatLight’s adherence to ISO quality standards, including ISO 9001:2015 certification, guarantees the quality and reliability of the 4 axis machined parts.
Comparison with Other Machining Methods
When compared to 3 axis CNC machining, 4 axis machining offers greater flexibility and the ability to create more complex parts. However, it is also more expensive in terms of equipment and programming. On the other hand, 5 axis CNC machining, which has two additional rotational axes compared to 3 axis machining, can create even more complex geometries than 4 axis machining. But 4 axis machining is often a more cost – effective solution for parts that don’t require the extreme complexity achievable with 5 axis machining.
