Rotary indexing machine

A rotary indexing machine, comprising:

• an indexing plate, which is in at least one operating state configured to accommodate and transport at least one work piece, the indexing plate comprising a plurality of gripping units, which grippers that are regularly distributed in a circumferential direction;
• and
• a clocking cell comprising:
• an accommodating unit with two oppositely-situated accommodating elements, which are configured for together accommodating the at least one work piece from the indexing plate and are further configured to grip the at least one work piece from opposite directions and to clamp the at least one work piece there between, and
• a machining unit for machining the at least one work piece accommodated by the accommodating unit, wherein the machining unit is configured for a turning machining of the at least one work piece accommodated by the accommodating unit, wherein the at least one work piece is driven, in a state when accommodated by the two accommodating elements, by the accommodating unit such that the at least one work piece rotates about a center axis,
• wherein the clocking cell further comprises a bridge unit, which extends at least partially over the indexing plate in an axial direction and is configured to guide the two accommodating elements of the accommodating unit in a shared coordinate system, wherein the machining unit is arranged on the bridge unit and wherein the clocking cell is movable as a whole with respect to the indexing plate, and
• wherein the clocking cell further comprises a drive unit by which the clocking cell is movable as a whole with respect to the indexing plate, and the drive unit comprises two guiding systems that are respectively arranged on opposing sides of the bridge unit and two drive motors that are arranged on the bridge unit.
