Johnford DMC Series double-column moving table bridge mill is created from a one-piece Meehanite® cast iron bridge/column assembly that takes up 30 percent less floor space than comparable C-frame vertical machining centers. Available in both moving table and sliding column (fixed-table) versions, the bridge mills have a long base casting with complete support of the table over the full 51 inches of Y-axis travel, allowing massive loads to be machined.
