Laser
Edge Mechanics from Aerotech
The
hard cover design provides protection from sparking
and
other debris introduced in the laser process. The robust
impregnated
aluminum
cover is protected with a Teflon
TM
coating
that provides a Rockwell 62 hardness making it
impervious
to scratching.
Side
seals keep dirt and particulates out of the stage,
protecting
bearing surfaces and linear encoders from
contamination.
The vertical orientation of the sealing
surface
deflects debris away from the stage. Competitive top
seal
designs can collect this debris, requiring a periodic
cleaning
maintenance procedure and the eventual failure
and
replacement of the sealing mechanism.
Direct-drive
linear motors provide the highest acceleration
and
velocity with the lowest maintenance and total cost of
ownership
of any competing drive technology. Direct drive
has
superior velocity control to ensure good edge quality on
laser
cutting and marking processes, while linear encoder
feedback
greatly improves overall system accuracy and
repeatability.
Laser
Edge mechanics include direct-drive rotary stages.
These
stages come in many configurations to meet the
price/performance
goals of laser manufacturing
applications.
LaserEdge rotary stages use slotless, brushless
motors
for cog-free operation. Clear apertures up to 100 mm
provide
clearance for beam delivery or feed-through of
pneumatic
or electrical control signals.
