This advanced manufacturing process represents a significant leap forward from traditional machining methods, offering a host of capabilities that are revolutionizing the way complex parts are produced.
4 - Axis Machining involves the utilization of Computer Numerical Control (CNC) machines that can move along four axes simultaneously. In a standard three - axis machining setup, operations occur along the X, Y, and Z axes, which are responsible for linear movements in different directions. However, 4 - Axis Machining adds an additional rotational axis, typically denoted as the A or B axis. This extra degree of freedom enables the cutting tool and the workpiece to interact in ways that were previously unattainable. For instance, it allows for continuous machining around the circumference of a part, opening up the possibility of creating intricate geometries and features that would be extremely challenging, if not impossible, with 3 - axis machining.
The applications of Yigu Technology 4 - Axis Machining span across a wide range of industries, from aerospace and automotive to medical and electronics. As manufacturers strive to meet the ever - increasing demands for high - quality, complex components, understanding the advantages of 4 - Axis Machining becomes crucial. In the following sections, we will delve deep into the numerous benefits that this technology brings to the manufacturing table, exploring how it can transform production processes and drive innovation.
2. Key Advantages
2.1 Increased Efficiency and Productivity
In the manufacturing landscape, efficiency and productivity are the cornerstones of success. 4 - Axis Machining offers a significant edge in this regard when compared to traditional 3 - Axis Machining.
Traditional 3 - Axis Machining typically requires multiple setups for complex parts. Each setup not only takes time for tool changes but also for manual adjustments to ensure the workpiece is properly aligned. For instance, in the production of a complex automotive engine component, a 3 - Axis machine might need to be re - set up 3 - 5 times, with each setup taking approximately 30 - 60 minutes. This not only lengthens the production time but also increases the chances of human error during the adjustment process.
In contrast, 4 - Axis Machining can perform multiple operations in a single setup. A case study by a leading automotive parts manufacturer showed that when switching from 3 - Axis to 4 - Axis Machining for the production of a specific transmission part, the production time per unit was reduced from 8 hours to 5 hours. This was achieved because the 4 - Axis machine could access multiple sides of the workpiece without the need for re - clamping. The additional rotational axis allowed for continuous machining around the circumference of the part, enabling features on different surfaces to be created in one go. As a result, the company was able to increase its production output by 30 - 40% within the same time frame, making 4 - Axis Machining a game - changer for both small - scale prototyping and large - scale production runs.
2.2 Improved Accuracy and Precision

6. FAQs
What is the difference between 4 - axis machining and 3 - axis machining?
The primary difference lies in the additional rotational axis in 4 - axis machining. In 3 - axis machining, operations are limited to the X, Y, and Z linear axes. This restricts the machine to move the cutting tool in straight - line directions, which is suitable for simple geometries like flat - surface milling, basic drilling, and simple 2D or 2.5D operations. For example, when manufacturing a simple rectangular bracket, a 3 - axis machine can easily mill the flat surfaces and drill holes in a straightforward manner.
However, Yigu Technology 4 - axis machining adds a rotational axis, typically denoted as the A or B axis. This extra degree of freedom allows the workpiece or the cutting tool to rotate while the machining process is ongoing. Consider a scenario where you need to create a part with angled holes on the side of a cylindrical component. With a 3 - axis machine, you would need to re - position the workpiece multiple times, which is time - consuming and can introduce errors. In contrast, a 4 - axis machine can rotate the workpiece around the additional axis, enabling the creation of these angled holes in a single setup. This not only improves the efficiency of the machining process but also enhances the precision of the final product, as there are fewer chances for cumulative errors that can occur during multiple setups.
