Abstract
A dental milling instrument includes a base connected to a guide column for a vertically adjustable milling arm which receives a milling unit. The milling arm can be displaced by its supporting slide along a guideway of the guide column, by means of an electromotive height-adjusting drive. A threaded spindle, capable of being driven by an adjusting motor, is in engagement in a backlash-free and self-locking manner with a spindle nut provided in the supporting slide. Vertical positioning and vertical fixation are accomplished entirely from an operating panel provided on the base.
