Abstract: A fixture for drilling sheets of fragile material is connectable to a movable machining head having a supporting structure and a rotary member, and includes a supporting frame, a shank for connecting the supporting frame to the supporting structure, and a first and at least a second powered spindle for a first and, respectively, a second drilling tool and extending in opposite directions with respect to the supporting frame; the spindles being rotated about respective axes parallel to each other by a transmission, an input member of which is connected to the rotary member of the machining head.

Abstract: A machine for working sheets of fragile material has a base; a supporting surface for supporting the work sheets; and a machining head powered to move over the supporting surface and perform machining operations on the sheets; the supporting surface having a partition wall movable between a partitioning position extending above the supporting surface and defining, on the supporting surface, two completely separate work stations, and a rest position in which the wall is located clear of the supporting surface.
