ABSTRACT:
A face-driver assembly and method for accurate coupling of a face driver with the spindle of a rotary-drive machining device. The assembly includes a face driver, a hub on the spindle defining a prealignment bore, a pair of self-centering coacting tooth sets on the hub and face driver, an engagement post extending into the hub and forming a prealignment shaft closely complementary to the prealignment bore, and a releasable coupling to hold and draw the engagement post rearwardly and thereby join the tooth sets in a manner facilitating final accurate centering.
