Spraying machine for cutting by electroerosion (electron discharge machining) with an electrode wire including: - a supporting structure with a baseplate composed of vertical elements arranged so as to delimit a container which is open towards the machining zone, the workpiece and its clamping system being mounted on posts fixed directly to these elements, and - a lower machining head equipped with two rollers (12, 13) intended to trap and entrain the wire (8), and arranged so that the used wire, leaving the lower machining head, is already in the space delimited by the elements of the baseplate and acting as a receptacle and in the bottom of which it is accumulated. A motor drives the two rollers (12, 13) with a rotational speed which is programmable and accurately slaved. Their pressure on the wire can be adjusted as a function of their diameter. They are arranged also to act as a wire guide and as contacts supplying the electrical current to the wire. <IMAGE>
