Abstract

La présente invention concerne un centre de travail multifonctionnel à commande électronique pouvant être utilisé pour usiner des plaques de pierre naturelle ou synthétique ou des plaques de verre. Le centre de travail est conçu pour effectuer à la fois les opérations de coupe sur une plaque (L1, L2) et les opérations d'usinage sur les bords des parties de plaque (L1A, L1B, L2A, L2B) obtenues suite à l'opération de coupe, sans qu'il soit nécessaire d'agencer un plan sacrificiel au-dessus du sommet de la machine pour effectuer l'opération de coupe. Le dessus de machine (3) est pourvu d'une pluralité d'unités de support et de maintien (8) montées de manière mobile dans une direction horizontale Y sur des traverses de support respectives (9), qui à leur tour sont montées de manière mobile sur le sommet de machine (3) dans une direction X perpendiculaire à la direction Y. L'unité de commande électronique (E) du centre de travail positionne une pluralité d'unités de support et de maintien (8) sélectionnées pour recevoir une plaque (L1, L2) à découper de manière à toutes les maintenir sur les deux côtés de la ligne de coupe (T). Après la réalisation d'une opération de coupe, les parties de plaque (L1A, L1B, L2A, L2B), qui ont été subdivisées à partir de ladite plaque (L1, L2), sont séparées par un mouvement le long de ladite seconde direction horizontale (X) des traverses (9) portant certaines desdites unités sélectionnées (8) et/ou un déplacement d'au moins certaines desdites unités sélectionnées le long de ladite première direction horizontale (Y). De cette manière, la tête d'usinage (7) du centre de travail peut effectuer l'usinage des bords des parties de plaque mentionnées ci-dessus (L1A, L1B, L2A, L2B) sur le même sommet de machine (3). En variante, les unités de support et de maintien (8) peuvent également réaliser un mouvement vertical, qui peut être utilisé pour séparer les parties de plaque coupées.
