Description:

The 4th axis adds a great deal of additional functionality to your CNC machine that you wouldn't normally get otherwise. A 4th axis can be used to cut along an arc, or be used in what is called indexing mode or continuous mode, meaning the cutting is done from a stationary point or while in full (continuous) rotation. The 4th axis makes machining something complex like a gear possible.

[4th Axis with Tail Stock] is therer a harmonic or planitary gearbox in nthe headstock, or is it just driven by the pully?

No, the motor shaft is directly coupled to the chuck via timing belts and drive pulleys. The mechanical advantage in this system is by using a small drive pulley on the motor shaft to the larger drive pulley on the shaft of the chuck.

[4th Axis with Tail Stock] what I need to buy to make this work on my GreenBull machine and the redfly?

Since this 4th axis already comes with a stepper motor, you will need a driver and some cable to connect to the driver from where the 4th axis will be placed. If you have extra space in the redFly electronics enclosure, you can fasten the driver there. You will also need some wire to connect the driver to the breakout baord.
