To the left is the control pendant for the VF series. The current models come with the Acu-Rite LCD graphical digital readout as standard equipment.

Controls on the Panel:
At the top left is the spindle speed display. Under the display is the speed setting knob and the forward - stop - reverse switch.

In the middle and are under the white safety bar making them a bit hard to see are the joysticks for axis selection  

Just below the joysticks are the geared knobs for sensitive feed rate setting. Feed rates are displayed on the digital readout.  On the knee mills X and Y have the feed knobs and the vertical knee lift just had the joystick for rapid positioning. On the bed mill versios all 3 axes have feed knobs.
Below the feed knobs are the yellow buttons for the rapid traverse for each axis. 

The lower switches are for the worklight and coolant on the left and an
E-stop on the right.
The electronics cabinet is oversized to allow for future upgrading to a CNC.  The X and Y axis already have CNC class amplifiers and axis motors, as well as the spindle drive.  You can see in the top left corner of the panel a blank space where the CNC control can be fitted.  Minimal wiring changes and pre-fitted components make the CNC upgrade very economical.
