A numeric-control work-centre for machining plates of glass, marble and natural or synthetic stones comprises: a bench, defining a work surface, designed to receive the plates to be machined; two fixed side members, set at the two sides of the work surface; an overhead cross-member, guided over the two side members like an overhead-travelling crane, in a horizontal direction Y orthogonal to the horizontal direction X of the cross-member; and a carriage, which is mobile in the aforesaid horizontal direction X on the cross-member, present in which are two work heads carried by a slide, mounted on the carriage so that, during machining of the edge of a plate, consecutive passing of the first tool and of the second tool in any order is obtained with one and the same movement of the carriage and/or of the cross-member of the work-centre.
