The Franklin Web Plasma Cutting system is a combination of unique
material handling and high performance CNC Plasma cutting machine.
Raw sheets are automatically retrieved and loaded by a Programmable
Gantry system. Each plate is loaded onto the infeed conveyor and
squared by hydraulic pushers. The plates are then moved by the
powered roller conveyor on the driven plasma slat table. Once the
webs or other parts are cut, the plasma slat table conveys forward
unloading the completed parts and skeleton.
The CNC Plasma Cutting Machine contains
brushless AC servo drives and planetary gear boxes providing positioning
speed up to 1000 IPM. Planetary gear boxes in both X and Y axis
virtually eliminate backlash while providing a smooth consistent
motion. A two (2) inch wide stainless steel band positions the
carriages. Proper X-axis pinion engagement is assured via a unique
spring cam arrangement. Built per ISO 230-2 Acceptance Code for
machine tools using a laser interferometer. Both X and Y axis
contain an .018" accuracy (in 72" travel), .005"
repeatability.
The Web Plate Conveyor is located
directly under the overhead Gantry loading rails. The conveyor
uses AC/VF drives and contains hydraulic datum pushers for squaring the
loaded sheet.
The preceding material can be stored in
programmable bin locations while the current sheet is being
processed. Floor mounted low rail on the material load end
provides easy loading of heavy stacks direct to storage
area.
The Vacuum Gantry can load up to two (2) plasma lines
with storage depths up to 80-ft travel. The gantry is semi-automatic
with touch screen control. Bin locations are programmable by plate
size and section. Sheet sizes are optional from 20-60 foot in
length x 72" wide. Vacuum lifter has material contact sensors
and vacuum monitor for safe automatic pick and place operation.
