1. the regulating method of a static pressure extensible guide straight-line degree, this hydrostatic slideway comprises moving guide rail (1), decides guide rail (2), moving guide rail (1) and decide to isolate by static pressure oil film (3) between guide rail (2), it is characterized in that:

  • when moving guide rail (1) is being decided to move on the guide rail (2), minimum point is a reference point when moving with moving guide rail (1), and each point is at the straightness error of short transverse when measuring moving guide rail (1) motion;

    Deciding to adorn secondary guide rail (4) on the guide rail (2), the moving direction of secondary guide rail (4) is identical with moving guide rail (1), and is synchronized with the movement with moving guide rail (1), and secondary guide rail (4) is gone up dress electromagnetic coil (5), on moving guide rail (1) relevant position electromagnetic core (6) is housed;

    Go up the height error value of each point with respect to reference point according to the moving guide rail of measuring (1), required power when measuring each point and being depressed into reference point calculates electromagnetic core (6) and produces the needed current/voltage value of this suction;

    Pass to the current/voltage value of each point correspondence on the electromagnetic coil (5) of secondary guide rail (4), the suffered electromagnetic force of electromagnetic core (6) each point makes guide rail (1) go up each point and moves on the straight straight line of reference point all the time.
