7-4 Tailstock Center Line Adjustment
Fig. 7-3
1. First, unclamp the tailstock body clamping lever
○ A
, and then loosen the two hexagon head
screws (shown as
○ B
) on both right and left side which lock the tailstock body and base together.
Determine the direction and amount of the misalignment for adjustment by positioning a test
bar between two dead centers. Unscrew the rear ‘gib screw’ (say one half turn). Then screw in
front side’s gib screw and tighten the other until the required setting or correct alignment is
achieved. Carefully retighten the rear and front gib screws which were loosened before and
recheck alignment. Retighten the two hexagon head screw carefully and re-clamp the tailstock.
(figure 7-4)
2. After tailstock body clamping lever is released, if the handwheel is turning tightly, the probable
cause is that the clamping blocks have not loosened. To solve the situation, please push the
tailstock body clamping lever forward one time for remedy.
