4 Axis CNC Machining in 2020: The Definitive Guide

The addition of a 4th Axis to your machine can add flexibility and customization to the process. A 4th axis allows the easier creation of arcs and complex designs, in manners not possible with a 3-axis setup. The ability to index certain materials like gear teeth, allows for a much more precise creation than using other techniques. Wrapping, and continuous curved applications can be done superbly with a CNC machine using the 4th axis and CAM software.

Key Takeaways:

  • Adding a 4th Axis to a CNC machine adds flexibility and customization options not previously available.
  • Rotary tables with worm gear are a good way to use the 4th axis in a low-intensity environment.
  • A timing belt usually prevents the gearing down required to be effective, even in combination with servos.

“A 4th axis is typically either used in an “indexing” mode or a “continuous” mode. When indexing, no cutting happens until the 4th axis is stopped (and often locked with a brake of some kind).”
