SCRAP REMOVAL
The scrap removal system is designed to remove scrap material from the cutting area after processing. The
system components are: scraper plates attached to the lower pallet, scrap tray mounted on top of the fume
collection plenum, and a scrap cart with removable scrap totes.
When cutting has completed on the lower pallet and the pallets change positions, the lower pallet will move from
the main frame to the load frame. As the pallet moves, the scraper plates push scrap accumulated on the scrap
tray into scrap totes located near the load frame end of the main frame.
When the pallet lls the scrap cart, pull the scrap cart out of the main frame and empty the totes.
Clean the scraper plates to remove laser slag as needed. To remove a plate, pull the pin from the hinge and
lift the plate out. Clean the scrap trays if slag build-up prevents the scraper plates from functioning properly or
inhibits proper fume collection. Also clean the pull-out totes.
Fire hazard is present in the processing area
through interaction of the laser beam with
materials present in the work area.
Debris and ne particulate generated from laser cutting some materials, (i.e. plastics, aluminum, fabrics, etc.),
can present a re hazard if allowed to accumulate. Good housekeeping practice should be followed so the area
below the cutting zone is inspected daily and cleaned on an as-needed basis or every 1000 hours of operation.
The fume collection plenum (air collection duct) below the cutting zone should also be checked for debris
accumulation. Removable covers are provided for this inspection and cleaning. See Section 3 - SAFETY,
FIRE, for more information.
PALLET GUIDE RAILS
Maintenance required for the pallet guides consists of periodic cleaning of the guide rails in the Main Frame
and Load Frame.
Remove dirt and debris from the entire length of the upper and lower rails on a regular basis. As a guideline,
inspect the rails weekly and, if necessary, clean with a stiff brush and a non-ammable, nontoxic solvent.
