to provide a sequence of machining stations, a load/unload station for the mounting of workpieces on the fixtures and their removal therefrom, and a motor for driving the turntable in an indexing fashion to bring workpieces held in the fixtures successively into registry with the machining stations. Each tool support includes at least one X-Y positioner which in turn supports a machining tool such as a reciprocating drill. Each machining tool, its associated X.Y positioner, and the turntable are actuated by a control such that the turntables index the workpieces to successive machining stations, and at each station, the X-Y positioners repeatedly position their respective machining tools independently of each other such that each machining tool performs a series of repetitive machining operations within a separate predetermined area on the workpiece.
