The FXB vertical machining center's double table version is shown equipped with CMS' patented "ring pressing device" for routing parts from stacked aluminum sheets. This eliminates the need for hundreds of screws or rivets to hold the sheets together for the routing of the groups of nested parts, which are held in place only by micro tabs which join them to the stack of sheets. This process is then followed by the difficult, tedious handwork of removing the micro tabs which still remain on these parts, which were created for the sake of the traditional production method. FXB's "ring pressing device" provides the most efficient, cost effective, high quality and automated process available for stacked sheet aluminum production.
