An actuating assembly ( 50 ) for ink jet printheads consists of a silicon die ( 61 ), which comprises a groove ( 45 ) and a lamina ( 64 ), and of a structure ( 75 ) produced monolithically in the same production process. The actuating assembly ( 50 ) comprises a microhydraulics ( 63 ), the latter in turn comprising a plurality of channels ( 67 ) and chambers ( 57 ), made inside the structure ( 75 ) by means of a sacrificial metallic layer ( 54 ). A conducting layer ( 26 ) forms a single interconnected equipotential network used as the electrode during the processes of electrochemical etch stopping on the groove ( 45 ), of electrodeposition of the sacrificial layer ( 54 ) and of the latter's subsequent removal.
