For the error adjustment in vertical direction, according to the detection result of the dial indicator, if the overall position of the tailstock end mechanism is lower than the position of the spindle box, it is necessary to remove and lift the tailstock end mechanism, and add standard cop- per plates to the lower plane of the sliding table to ensure the tailstock end mechanism is coaxial with the spindle box mechanism in vertical direction.
