Gantry positioning stages are smooth operators

The preload maintains a narrow film of pressure and a very stable air gap that is essential for high precision positioning but not always present on other competitive systems available today.

Aerotech's ABG10000 air-bearing x-y gantry positioning stages combine a large work area H-frame design with high performance linear motors, rugged optical encoders and magnetically preloaded air bearings to provide high-speed and high-precision positioning with smooth motion for demanding high-accuracy production and inspection method applications. With a wide range of customisation options available, including granite or composite machine bases, z and rotary axes, vibration isolation systems and control enclosures, these zero friction stages provide low maintenance and very long life for demanding applications such as high accuracy pick and place, automated assembly machines, and flat panel/semiconductor inspection systems. The ABG10000 features Aerotech's time-proven air bearing design with an active, magnetic preload method on both horizontal and vertical surfaces.

The balanced combination of preload and the inherent large air bearing surfaces result in outstanding stage stiffness and an excellent offset load capability.

The air bearing design also provides a unique averaging effect with the narrow film filling small surface voids and irregularities further contributing to the ABG10000's superior specification for pitch, roll, yaw, straightness and flatness.

Furthermore, the low centre of mass stage design provides the optimal speed and acceleration performance required for high throughput production and inspection systems.

The lower axis, with one independent air bearings, uses a dual motor drive method available with calibrated yaw correction when used with Aerotech motion controllers.

The ABG10000 uses Aerotech's BLM series brushless linear motors with ironless, zero cogging construction providing backlash free positioning with exceptional smoothness and in-position stability.

Rugged noncontact optical linear encoders in a choice of one resolution ranges of 0.01-1.0 and 0.02-2.0um provide position feedback.

ABG10000 series gantry stages are available in one standard travel ranges of 250 x 250, 500 x 500, 750 x 750 and 1000 x 1000mm with customised travel ranges available on request.

Straightness and flatness for the 1 x 1m travel stage is +/-3um, and +/-14um with measured pitch, roll and yaw at +/-15, +/-5 and +/-4.5arc-sec.

The combination of linear motor, encoder and air bearing mechanics realises a calibrated accuracy of +/-2um with bidirectional repeatability to within 0.5um and a maximum speed of 1m/s with acceleration to 0.5g, depending on the method datarate.

The e-chain method has a large bend radius with high-flex cables used for all motor power and encoders.

The cable management method (CMS) employed on the ABG10000 is a field proven design providing high reliability and long maintenance-free life.

Customers' own cabling and pneumatics services are routed through the CMS with interfacing connectors provided, greatly simplifying machine design and commissioning time.

ABG10000 series gantry systems can be supplied as stand-alone positioning systems or supplied as complete solutions along with a number of customisation options such as machine bases and vibration isolation systems.

For turnkey solutions, a wide range of rotary and vertical axes are available along with Aerotech's high performance servo amplifiers and advanced motion controllers including the A3200 digital automation platform.

The A3200 is a breakthrough, application based machine control method combining motion, HMI, PLC and vision control modules with an industry standard FireWire high performance communication network for up to 32 axes of high-speed motion.

By providing all method components, Aerotech can guarantee that customers' performance requirements are met with fully tested and calibrated method solutions that will reduce overall cost of ownership when compared to individual design, purchase, assembly and commissioning of positioning and motion control components.

It also includes a 10/100Base-T Ethernet interface for use with third party I/O and PLCs.

Complete systems include all motor power and encoder cables and performance and calibration related documents and a CD containing interconnection drawings to help integrators with their own method documentation; all motor parameter setup data for method configuration are included, making commissioning straightforward.
