Aerotech's ASR1200 series
is an extension of the successful ASR1100 series direct-drive rotary stage.
The ASR1200 includes the integral pneumatically operated collet chuck for automated
material handling that is found on the ASR1100, but the ASR1200 also includes
a sealed water jacket for wet cutting processes.
Integral Collet Design
The collet chuck on the ASR1200 accepts ER16 series collets, which are readily
available in sizes that support tube diameters from 0.5 mm to 5.8 mm. The collet
is retained with a threaded retaining cap that enables quick-changeover. The
collet is configured in a "fail-safe" mode where full clamping force
is applied when no air pressure is present.
Air is delivered to the
rotating collet assembly through a custom-designed frictionless, seal-less rotary
union. This 100% noncontact rotary union design ensures a lifetime of maintenance-free
operation. The combination collet chuck and rotary union also has significantly
less friction and inertia than external assemblies created from discrete parts.
This reduced inertia improves system performance by allowing higher peak acceleration
and reducing position error during laser machining operations.
Fluid Delivery System
The ASR1200 includes a fluid delivery system and seal assembly to support wet
cutting processes. The rear of the unit has a quick release fitting for fluid
input and an NPT thread that allows the user to customize the length of the
"water jacket" to match the length of the tube material. Inside the
ASR1200 is an O-ring assembly that seals the tubing against the I.D. of the
ASR1200 shaft. This seal assembly rotates with the tubing, eliminating troublesome
torsion-induced errors that are present when working with thin-walled tubing
or extremely flexible materials such as Nitinol.
Direct Drive
The ASR1200 series utilizes Aerotech's direct-drive brushless motor technology
to maximize positioning performance. Direct-drive technology is optimized for
24/7 production environments because there are no brushes to replace and no
gear trains or belts to maintain. Direct drive also provides quicker acceleration
and higher top speeds than gear- or belt-driven mechanisms, which means higher
total overall throughput.
The low maintenance and high throughput characteristics of the ASR1200 provide
a stage that yields the lowest total cost of ownership while the integral water
jacket and pneumatic collet provide unmatched levels of integration and ease
of use.
