Aerotech’s AXR integrated two-axis rotary assembly provides high-speed machining capabilities for complex 3D part geometries. The precision-aligned system allows accurate positioning on a hemispherical surface. Multiple frame sizes with direct- or gear-driven options provide a wide range of load carrying capability.

Direct-Drive Yaw Axis

All AXR series rotary combinations feature a direct-drive yaw (B) axis. Direct-drive motors exhibit significantly higher throughput and maintenance-free operation when compared to gear- and screw-driven technology. With peak rotation speeds of up to 1000 rpm, the AXR is capable of supporting high-speed machining processes. A high-resolution encoder enables the axis to run at extremely slow speeds while maintaining excellent velocity regulation and positioning accuracy.

High-Capacity Tilt Axis

The AXR has both direct-drive and gear-driven tilt (A) axis configurations to meet the performance requirements of your specific application. The direct-drive version provides the highest possible operating speed and accuracy for demanding applications. A modular counterbalance system and different yaw mounting heights are available to balance offset loads. The tilt axis can be equipped with a brake to hold axis position when power is removed. For large load applications, the gear-drive units provide significantly higher continuous torque output while the drive mechanism limits motion in the power-off state. The precision anti-backlash gearing enables this higher torque output while still maintaining excellent accuracy and repeatability performance.

Material Handling

The AXR comes standard with an integral rotary union that provides a single pneumatic control signal to the yaw-axis tabletop for customer supplied air- or vacuum-actuated tooling. The AXR can also be outfitted with a 3-jaw manual chuck for maximum part-holding flexibility.

Scalable Product Solutions

With both direct-drive and gear-driven platforms, various yaw table locations, a scalable counterbalance, standard pneumatic feed-through, and an optional 3-jaw chuck, the AXR can be configured to meet the requirements of most two-axis rotary assemblies.

Specifications

AXR Specifications

1. Certified with each stage.

2. On-axis loading is listed.

3. All error motion specifications are measured at 60 rpm.

Ordering Information

AXR Two-Axis Rotary Assembly

AXR Series (Required)

Axis Configuration (Required)

Yaw Axis Configuration (Required)

Note: 0E option not available on gear-driven AXRs (150G). Gearbox has sufficient holding torque to balance maximum moment load.

Brake Configuration (Optional)

Sealing Configuration (Optional)

Counterweight Configuration (Optional)

1. Offset loads include both the payload and stage unbalance.

2. A linear combination of counterweight kits can be employed to achieve balance. See counterbalance chart to determine if application falls within balance limits.

Integration (Required)

Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.
