A-ABT-XY-360*360
A-ABT-XY-360*360 combines marble structure, linear motors and air bearings for high accuracy, straightness and flatness. It suits tiny-step/ultraprecise positioning, optical alignment, assembly, machining and semiconductor microscopy inspection. A higher-precision ceramic version uses high-purity alumina air-bearing structures/guides. Compared with granite/metal, alumina offers lower expansion and improved straightness, hardness and wear resistance.
