Quill on a CNC Machining Center – what is it ?

On a CNC machining center, the quill is an extendable part of the spindle that is used to machine areas that are difficult to reach. The spindle is the Z axis, and the quill is the W axis.

You can program the Z and W axes independently – position the Z axis at some point, and then extend the W alone. The max. quill traverse distance could be between 500 to 1000 mm. The quill’s rapid rate is typically lower than that of the other axes, maybe 5 to 10 m/min against the 20-40 m/min of the other axes.
