4-axis machining refers to adding a rotating axis, usually A or B axis, to 3-axis machining to achieve rotational motion on the fourth axis.

This machining method can produce more complex parts and components, and can process parts with three-dimensional surfaces.
By adding the fourth axis, the part can rotate along the rotating axis, thereby achieving machining at different angles. For example, by installing a fixture on the rotating axis, it is possible to process annular workpieces. Moreover, more complex machining operations can be achieved by programming the rotation angle on the rotating axis.

4-axis machining is often used for complex parts machining in industries such as automobiles, molds, and aerospace. In addition to various machining operations of 3-axis machining, complex surface curves can also be machined without disassembling the workpiece. At the same time, 4-axis machining has a high degree of automation and a fast processing speed, making it more suitable for mass production.

Compared with 3-axis machining, 4-axis machining has a wider range of applicability and can process more complex and precise parts and components. The main features are:
1. With internal or external surfaces. Under the control of the fourth rotating axis, complex curved surface processing can be achieved, such as ellipses, spirals, cones, spheres, etc.
2. Complex shapes. 4-axis machining can be processed at different angles, and parts can be processed at various angles of the rotating axis. The processed workpiece has a more complex shape and higher precision.
3. Fast processing speed. Compared with traditional manual processing and forming processing, 4-axis machining has a higher level of automation and processing speed, which can not only improve production efficiency, but also ensure processing accuracy and quality.
4. Wide range of applications. 4-axis machining is widely used in mold manufacturing, automobiles, motorcycles, aviation, aerospace, electronics and other industries, and can manufacture some parts with complex shapes, such as bearing seats, aluminum threaded transfer joints, and molds with complex shapes.
Therefore, 4-axis machining adds a rotating axis on the basis of 3-axis machining, has higher processing accuracy and more complex processing forms, and is suitable for the processing and manufacturing of parts with complex shapes and high precision requirements.
