Aerotech has launched a wide-base version of its ABL1500 air-bearing linear translation stage for high-precision positioning of heavy and offset loads.

It can also be used as a base for X-Y systems where maximum support is essential.

The ABL1500WB has a nominal width of 400mm and is available in four travel options from 200 to 500mm.

With a powerful dual linear motor drive and choice of standard precision or high-accuracy linear encoders, the stage can support a direct load of 60kg with submicron resolution and accuracy, and with speed/acceleration up to 2m/sec and 2g.

Aimed at high-throughput manufacturing and test applications in semiconductor or nanotechnology production that require high-performance scanning or step and repeat positioning, the all-aluminium stage benefits from Aerotech’s active air preload system for certified straightness/flatness of under +/- 2.0um for the 500mm travel version (+/-0.5um for the 200mm version).

A choice of standard or HALAR calibrated accuracy is available for each travel version and each encoder option.

HALAR calibration includes an extensive interferometer-based measurement procedure for improved accuracy and repeatability, with the variation between the encoder position and the actual stage position placed as a look up table in the Aerotech motion controller.

For the 500mm travel version, HALAR calibration yields a straight line accuracy of +/- 0.5um with a bidirectional repeatability of +/-0.2um.

Aerotech’s active air bearing design maintains equal pressure on both vertical and horizontal bearing surfaces and distributes the stage load over the maximum area, resulting in high stage stiffness with strong offset load handling characteristics.

With brushless linear servo motors, non-contacting encoders and air bearings, the stage has negligible friction and is specified for a 30,000 hour MTBF life with minimal maintenance requirements.

The dual BLMC series brushless linear servomotors provide smooth, backlash-free motion and a choice of Aerotech’s PWM or linear technology amplifiers allows the user to select the best performance characteristics for the application.

HP series PWM amplifiers will suit micron-level resolution and provide high speeds and acceleration performance, but for ultimate position and speed control combined with nanometre level in-position stability Aerotech’s HL and ML series linear stage amplifiers are essential – according to the company.

The ABL1500WB may be supplied individually or with other Aerotech positioning mechanics as a multi-axis engineered system, complete with chain-type cable management and orthogonality to within 2 arc-sec.

Engineered systems enable OEMs and machine builders to realise their automation needs and can include granite base, cabinet frames, special fixtures and a choice of advanced motion and machine controls that combine to improve development timescales, production throughput and the final quality of the customers’ product.
