ABSTRACT:
A dental technician's work station is provided with a hand-held machining device and a suction device for removal of dust resulting from machining. Connection of the machining device to the suction device by a common data bus is provided, and the parameters corresponding to the machining device are input and used to control both the hand-held machining device and the suction device. The suction device is thus always adjusted automatically to match the respective handling step using a specific machining bit. An especially fast and certain adjustment of the machining unit and/or the suction device by means of selector keys is effected, these keys having respective symbols for the particular machining bits utilized. The speed of the matching unit and, in an especially advantageous embodiment, the suction device as well, are thus adjusted correctly and simultaneously with a single key stroke.
