The AirBeam Series is ideal for Computer-To-Plate systems,
photoplotters, wafer scanning systems, and factory automation
applications. It provides straight, stiff, cog-free motion at
resolutions less than a micron. The AirBeam combines
breakthrough linear servo motor technology and an ultrasmooth
air bearing way in a single structural beam. The linear
motor and modular, serviceable moving cable set are
uniquely mounted inside the main beam, minimizing particulate
generation. The integral linear motor allows carriage
speeds up to 1 meter per second, and accelerations up to 1
G. The linear encoder mounts just below the upper surface,
minimizing Abbé error. A laser interferometer option is available
for particularly demanding OEM applications with resolution
down to 2.5 nanometers. Since the air bearing carriage,
linear motor, and linear encoder are non-contact
devices, the AirBeam provides virtually unlimited life without
particle generation.
Danaher Precision Systems’ unique clog-free air bearing
technology provides superior reliability while eliminating
costly filtration requirements, and requires minimal air consumption.
The AirBeam series mounts via 3 points, eliminating
degradation of positioning accuracy due to imperfect
mounting surfaces. Locking, D sub-mini connectors with
strain-relieved cables mount on the box beam end plate to
provide convenient access to motor and limit/encoder signals.
An auxiliary connector is provided for user signals, and
terminates on the air bearing moving carriage. Please contact
one of our Applications Engineers when high stability is
needed. An optional solenoid may be added which rapidly
disables compressed air to the moving carriage, resulting in
a “Coulomb welded” state. In this state, motion between the
spar and carriage is eliminated at the atomic level, and the
only relative movement is due to thermal phenomena.
