Design Features

The ATS5000WB was designed to meet the needs of the most demanding applications. A rigid base, fully sealed metal waycovers and high-performance brushless servomotor make the ATS5000WB the stage of choice in industrial applications such as laser machining, ceramic scribing or any other application requiring high accuracy in a production environment.

Rugged Construction

The greatest attention to detail is evident in all aspects of the ATS5000WB\'s design. The tabletop utilizes stainless steel Helicoil™ inserts to protect mounting holes against thread wear. An integral metal waycover is provided to protect the stage from hot sparks or debris. Both the metal waycover and tabletop are treated with a hardcoat (Rockwell 62 hardness) that is scratch-resistant and provides outstanding protection in the harshest applications.

To further provide the stage with protection from a caustic environment, the ATS5000WB utilizes Aerotech\'s unique tensioned side-strap system. The straps are in a vertical orientation that prevents debris from accumulating on top of them and are tensioned to create a tight seal. An optional air-purge fitting is available that allows air to be forced into the body of the stage. This creates a positive pressure that prevents any particulate, no matter how fine, from entering the stage.

To aid in system assembly, the base mounting holes are located outboard of the stage. Therefore, the stage can be mounted without removing the hardcover.

Improved Performance

By increasing the overall width of the stage, the spacing between the linear bearings was dramatically increased. This wider spacing allows the ATS5000WB to handle high cantilever loads and still maintain the high accuracy expected of an Aerotech product. In XY systems, this wider base translates into greater support for the upper axis, effectively increasing its performance, particularly when handling a heavy load.

High precision options include noncontact linear encoders with submicron repeatabilities and HALAR and HALSF factory calibrations that further improve the standard accuracy, straightness and flatness specifications.

Motor and Drives

Included with all ATS5000WB series stages is Aerotech\'s high performance BM series brushless servomotor. Aerotech manufactures a wide range of matching drives and controls to provide a fully integrated and optimized solution. For maximum performance, a linear motor version is available – please refer to the ALS5000WB.
