The basic principle is though three root ball screw control platform, by the measurement of nozzle, three motor to adjustable height accordingly, easily implemented leveling!
Selection basis and method on allowable contact stress of rolling ball-socket nozzle were described. Based on empirical formula and test data, several factors affecting allowable stress were analyzed.
