3 Axis vs 4 Axis vs 5 Axis CNC Milling: Differences Contrast
Multi-axis milling, as the number of axes increases, the machining capacity is also enhanced accordingly, and more complex part designs can be processed. 5-axis CNC milling allows the largest machining range and flexibility, while 3-axis and 4-axis are relatively low.
3-axis CNC milling
- Definition: The most basic CNC milling configuration with three linear moving axes (X, Y, Z axes).
- Machining capabilities: Suitable for plane milling, grooves, bosses and other simple three-dimensional shapes.
- Application range: Widely used in mold manufacturing, automobiles, aerospace and other industries.
- Limitations: Complex bevel or curved surface machining is not easy because the tool axis is fixed.
4-axis CNC milling
- Definition: A rotary axis is added to the 3-axis, usually the A axis (rotation around the X axis) or the B axis (rotation around the Y axis). Machining capabilities: Capable of more complex bevel machining, but still limited to a single rotary axis.
- Application range: Suitable for machining parts with inclined surfaces or specific angle requirements.
- Advantages: Improved machining flexibility and can reduce the re-clamping of workpieces.
5-axis CNC milling:
- Definition: It has three linear moving axes (X, Y, Z axes) and two rotation axes (usually A axis and B axis or C axis).
- Machining capabilities: It can perform complex three-dimensional surface machining, including inclined planes, curves and complex spatial surfaces.
- Application range: It is very suitable for industries such as aerospace, medical equipment, and mold manufacturing, and is used to machine complex parts such as impellers, molds, etc.
- Advantages: It provides extremely high machining flexibility and precision, and can complete the machining of the entire part in one clamping.
