You probably know about 3-axis CNC milling. You might even be familiar with 5 axes. But did you know there’s also 6-axis CNC milling? Find out about this manufacturing marvel! The CNC milling machines most will be familiar with only operate on 3 axes: X, Y, and Z. This configuration is simple — just imagine a 3D printer and, instead of an extruder, it has a cutting tool that spins really really fast! Things get even more interesting with 5-axis CNC milling machines, which additionally execute rotations about the X- and Y-axes. The benefit is the ability to keep the cutting tool perpendicular to the material surface on multiple planes. This way, you can mill forms with overhangs that would be impossible to cut with a 3-axis machine (without a pause in milling to reorient the material, that is). And then there’s 6-axis CNC mills. The addition of another rotation axis, usually about the Z-axis this time, can cause a significant improvement in speed compared to 5-axis configurations. And that’s exactly the technological marvel we explore in this article.  The primary benefit 6-axis CNC milling offers over the closely-related 5-axis configuration is faster cutting times. With ...
