Numerically-controlled work centre for machining plates of glass, stone, marble and the like, with two or more machining heads

摘要

A numeric-control work-centre for machining plates of glass, marble and natural or synthetic stones comprises: a bench (2), defining a work surface (3), designed to receive the plates (L) to be machined; two fixed side members (4), set at the two sides of the work surface (3); an overhead cross-member (5), guided over the two side members (4) like an overhead-travelling crane, in a horizontal direction Y orthogonal to the horizontal direction X of the cross-member (5); and a carriage (6), which is mobile in the aforesaid horizontal direction X on the cross-member (5), present in which are two work heads (7, 11, 10, 10a) carried by a slide (24), mounted on the carriage (6) so that, during machining of the edge of a plate (L), consecutive passing of the first tool (9) and of the second tool (16) in any order is obtained with one and the same movement of the carriage (6) and/or of the cross-member (5) of the work-centre.
