Vertical portal centers

Decades of experience in the construction of vertical machining centres have led to this new machine concept. The gantry design offers highest rigidity and accuracy for surface milling. The two work tables enable a very efficient pendulum machining, and by synchronisation of the two Y-axes also the machining of long parts. The large traverse paths of the Y-axes do not affect the accuracy of the machining geometry at any position of the tables.
