CNC 5 Axis Milling Machines VS 3 Axis Machines: What's The Difference?

In CNC machining, moving from a 3 axis to a 5 axis milling machine will change your production. Knowing what sets them apart will help you in making a decision.

Movement and Complexity

3 Axis: Since 3 axis machines move on only the X, Y, and Z axes, they can do less very complex jobs. However, 5 axis machines are equipped with rotational movements about both the X and Y axes to be able to make more complicated geometries and detailed designs with increased accuracy.

Efficiency and Setup

Parts can be machined in a single setup with 5 axis machines. There is no need for several repositionings and setups as is usually the case with 3-axis machines. This procedure saves time, generally increasing efficiency and consistency.

Surface Finish

The advanced movement of 5 axis machines enables smoother and more accurate tool paths. These result in better surface finishes. This reduces the need to have further finishing processes.

Cost and Investment

While 5 axis machines are more of an up-front investment, their capacity for handling complicated tasks with enhanced efficiency usually pays for itself in the form of savings for high-demand, intricate projects.

Conclusion

Choosing between CNC 3 Axis and 5 Axis Milling Machines depends on your intended machining application. For complex, high-precision work, 5 axis machines are handy, while 3 axis machines remain optimal for less complicated and cost-effective tasks.
