Slide way and body of the linear ball stage is in one unit, and Gothic arc-groove ground precisely to meet requirement of high parallism and high flatness.Gothic arc-groove formed by dual arc-grooves individually on upper and lower rails of body. Ball moving in single groove is structured by 2 point-contact, and total 4 contact point in dual arc-groove to form strong rail construction. In case of rails of SUS-STAGE is to set ball assembly in arc-groove to save traditional adjustment and revision time. In addition, without adjustment screw would save accuracy problem and maintenance time caused by loosen screw, and cheaper as well.
