Johnford DMC Series double-column moving table bridge mill is created from a one-piece Meehanite cast iron bridge/column assembly that reportedly 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, ranging from 36- x 36- x 30-inches of travel up to 60-ft. x 20-ft., 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.

The Y and Z axes hold fixed loads at all times while the X-axis carries the only dynamic load allowing for tight machining and tight tolerances during high-speed machining operations. Because there is no table overhang, X-axis pitch and yaw are eliminated. The spindle centerline-to-column distance is minimized offering further rigidity. The machine's heavily ribbed cast iron construction provides long tool life and part surface finish. The combination of twin screw-type conveyors and a caterpillar conveyor ensures complete chip removal with little manual cleaning. Additionally, finite element analysis (FEA) is used to design each bridge mill, simulating the effects of real world conditions, including vibration, heat, fluid flow and other physical impacts.
