Johnford double columns are created from massive Meehanite iron castings. These bridge mills have a long base casting with complete support of the table over the full X-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 complete surround table guarding with 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.
The DMC-4100LH feature rigid box ways in Y and Z and Schneeberger roller ways in X for high load carrying capacity. Heavy duty 35HP, 2 speed gearbox driven spindles provide heaving cutting power and torque.
