Punching machine used advantageously, but not only, to prearrange substrates (20) for electrical micro-circuits, such as for example green-tape sheets, the machine having a supporting table movable on two axes (x, y) of the horizontal plane in cooperation with a punching stand (21), the punching stand (21) supporting a punching actuator movable on a vertical axis (z) and having at its lower end a mould element (44) and a matrix element (45), the flat table (19) which supports the substrate (20) being movable along the axis (x) and being rigidly associated at the lower end with a second flat table (12) movable along the axis (y), at least the actuations of the flat table (19) along the axis (x), those of the flat table (12) along the axis (y) and those of the punching actuator (22) along the axis (z) being achieved by means of the relative linear motors (13a, 13b, 13c, 13d) arranged with their axis parallel to the respective axis of movement (x, y, z), and at least the flat tables (12, 19) moving on a relative pneumostatic support and guide system (41, 42, 43; 141, 142, 143). <IMAGE> |
