1) Level
’s Zero Point Setting
① First, place the level at the center of the table and read the dimension of one part of
the level droplet accurately.
② At the same po
sition, rotate the Level 180 ° to read the droplet dimension in the same
direction.
③ Use the “- ”
screwdriver to rotate the origin adjustment screw so that the middle of the
droplet dimension (halfway between the two directions) between the first droplet
dimension and the droplet dimension when turning 180˚can move.
④ Repeat ①∼③
in order to make sure to adjust the water droplet to the same position
when turning in both directions.
※ How to read Level (example)
End position of right hand side water droplet
＋End of left hand side droplet ÷ 2＝Level
dimension (-50 + -40)÷2＝ -45
▪ The above level is 45 μ/m higher on the left.
※
When setting a level or leveling a machine, it
is a good practice to read the standard level
instead of reading the one on one side.

※ Note) Matters to be noted when performing the level operation
Prior to starting absolute level operation for 5-axes machine, be sure to check
the table top accuracy in advance, and correct in case of any irregularity.
▪ Table top accuracy check
(1) B-axis machine reference point
(2) Height difference in Y-axis direction table
