In today’s era of advanced product design, precision and efficiency are non-negotiable. That’s where 5-axis CNC milling shines — a cutting-edge solution enabling engineers and innovators to achieve complex geometries, intricate angles, and high-performance parts in a single setup.
Compared with traditional 3-axis machining, 5-axis CNC milling offers two additional rotational axes, providing a full range of motion that simplifies tool access, reduces setup time, and enhances surface finish.
If you’re looking for an expert partner in this domain, Boona Prototypes is a trusted name with deep expertise and advanced infrastructure tailored for prototype and low-volume precision production.
I. How Does 5-Axis CNC Milling Work?
Unlike conventional 3-axis systems that move along the X, Y, and Z axes, 5-axis CNC machines add two extra axes of rotation. This allows the cutting tool to approach the part from virtually any direction — ideal for undercuts, holes on compound angles, and freeform surfaces.
5-Axis Types:
-
Simultaneous (True) 5-Axis: All five axes move together to maintain tool alignment.
-
3+2 Axis (Positional): The rotational axes orient the part, then the milling occurs in 3 axes.
