A-GPA-XY
Vacuum-preloaded aerostatic guides. The X-axis beam uses alumina ceramic, offering better accuracy, stability and wear resistance than marble. A-GPA-XY linear-motor stages combine air-bearing guides and linear motors in a compact, low-profile structure with coplanar XY marble and 300*300 or 400*400mm travel. Excellent accuracy and straightness suit tiny-step or ultraprecise planar scanning, precision optical alignment, assembly and machining.
