ABRT-400空氣軸承精密直驅(qū)轉(zhuǎn)臺(tái) | ABRT-400 Air-Bearing Direct-Drive Rotary Stage | ABRT-400精密氣浮直驅(qū)轉(zhuǎn)臺(tái)
ABRT-400 是 Aerotech 的 μARC 角度和旋轉(zhuǎn)裝置校準(zhǔn)系統(tǒng)的核心。ABRT-400 是一個(gè)大的具備納米級誤差運(yùn)動(dòng)性能的旋轉(zhuǎn)空氣軸承主軸。這種高精度空氣軸承主軸是用鋼緊密配合μARC周圍的花崗巖結(jié)構(gòu)的CTE建造的。空氣軸承配備有不影響旋轉(zhuǎn)的接頭和滑環(huán)以通過真空或空氣，并且實(shí)現(xiàn)電氣連接到被測裝置。
ABRT-400 可以用作高精度測量設(shè)備的標(biāo)準(zhǔn)角度標(biāo)定，X射線衍射，蛋白質(zhì)晶體或高精度加工應(yīng)用。
