8.3 Leveling on the Z-axis bed (column bed)

※ Setting the reference point for the Z-axis level
(1) Place the level in either side of the column and read one-end gradation of the water
bubble of the level.
(2) Turn the level by 180 degrees before moving to the opposite side of the column.
Then, read the gradation in the same direction.
(3) With a plain screwdriver, adjust the reference point screw to set the level to an
intermediate gradation between initial gradation (before rotation) and gradation after
180 degrees of rotation.
(4) Repeat steps 1) through 3) above until rotation in either direction comes up with the
same result.
1) Place the completed level in the grinding side
of the column in the X and Z directions. Then,
while feeding the Z axis to the coordinates of
"Z0. Z310. Z625. Z9350. Z1250." in five distinct
steps, perform the leveling in the same way
with the X-axis leveling above.
▪ However, you must be careful for the change
to the X axis leveling while working on the Z
axis. (It is recommended to place another
level on the table for your reference.)
▪ It is recommended to make coordinate settings for the leveling in advance.
