ABSTRACT:
The drilling unit comprises a cross-piece secured to the base and two carriages supporting said two operating heads and sliding on said cross-piece. The two carriages are each displaced independently of one another along the axis by means of two nut and screw pairs, each of which is associated with one of the carriages. The screw of each nut and screw pairs is actuated by a corresponding reversible electric motor mounted on the cross-piece, whereas the nut is mounted on the corresponding carriage displaced outwards with respect to the head so as to allow the heads to move individually into a common machining zone on the table.
