System (10) for clamping sheets being machined, in particular flat sheets of glass to be machined on a vertical drill (12) or a similar operating machine, comprising a fixed work surface (15) for resting a sheet (L) in a respective machining position (P1) and one or more suction cups (21) which are associated with a vacuum circuit (26, 26a, 26b), wherein, when the sheet (L) is arranged in the machining position (P1), the suction cups (21) are activated by the vacuum circuit (26, 26a, 26b), in particular sucking air through them, so that the suction cups (21) cooperate making direct contact with the surface (L') of the sheet (L), resting on the work surface (15), so to clamp the sheet (L) stably in the machining position (P1), so that it may be machined. The clamping system (10) allows advantageously the clamping, so that they may be machined, both of sheets of "low emission" glass, which typically have a coating on one of their two surfaces, and of varyingly shaped sheets of glass, secure clamping of which would not be possible using simply pressers.
