 What's New?
I have used this rotary axis drive arrangement for quite a few jobs and it is very accurate and easy to use.
The new quill drive will allow fast peck drilling and quick retract movement for engraving operations where you must raise and lower the tool often.
Because it uses the rack and pinion drive on the spindle it cannot compete with a Z axis ballscrew drive in terms of accuracy in all conditions.

 Electric Traction Drives
A quill is described in the dictionary as, "the hollow stem of a feather" and "a bobbin or spindle", as well as a "feather" and, alternatively, what a porcupine has on its back.
In railway traction terms, a quill drive is where a hollow shaft is placed round the driving axle and the motor drives the quill rather than driving the axle as it does with a nose suspended drive.
The big advantage of such drives is that all the weight of the motor is carried in the bogie frame (so it is a frame mounted motor) instead of it being directly supported by the axle and therefore partially unsprung.

Quill drive is most suited to open hole drive and especially core drilling.

 John Stuart Mill [Internet Encyclopedia of Philosophy]
If a person is asked a question, and is at the moment unable to answer it, he may refresh his memory by turning to a memorandum which he carries about with him.
To expel it from these, is to drive it from its stronghold: and because this had never been effectually done, the intuitive school, even after what my father had written in his Analysis of Mind, had in appearance, and as far as published writings were concerned, on the whole the best of the argument.
As for the axioms which, together with the definition, form the basis of geometrical reasoning, they are in reality "experimental truths, generalizations from observation." The great argument for their a priori character is that their opposites are inconceivable.
