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.nbsp
