Ball screw support Installation steps: install to the platform and base.
1, Make slide and ball screw link temporary fixed by screws, to design the fixed end of temporary fixed to the base, the fixed end moving slider makes the screw set, adjust the screw to the center of the slider move smoothly.
2, When using the fixed end of the support seat as the reference point, adjust the screw and the sliding table, or the gap between the screw and the connecting block. When using the fixed end of the support seat as the reference point, the axle height of the high-speed support seat is high. (supports are square)
3, Move the support end of the slider to the screw, adjust the center point of the screw, move to the left to the right to check whether the slide is smooth, and then fix the system on the base for a while.
