A face-driver assembly (10) and method for accurate coupling of a face-driver (102) with the spindle (26) of a rotary-drive machining device. The assembly includes a face-driver, a hub (113) on the spindle defining a prealignment bore (144), a pair of self-centering coacting tooth sets (158, 160) on the hub and face-driver, an engagement post (130) extending into the hub and forming a prealignment shaft (196) closely complementary to the prealignment bore, and a releasable coupling (110) to hold and draw the engagement post rearwardly and thereby join the tooth sets in a manner facilitating final accurate centering. |
