ⓐ
Measure
Install the level on the grinding side of the
column in the X- and Z-axis direction and
set the reference point. Feed the Z axis in
3-divided stroke and check the greatest
difference of the level changes.

Measuring point
: Z0., Z800. (Z1000.), Z1600. (Z2000.)
▪
Tolerance: 0.030mm / full stroke

Correct
Incorrectness of the X-Y straightness of the

in the machine feeding level. So refer to
"Machine Leveling" later in this manual and
perform the leveling again.

indicator on the spindle head. Set either
end of the straight edge to “0” and move
the Z axis to check the greatest difference
(measurement in the middle of the
movement).

If the straight edge is not available, use
the sides of the square that is required for
measuring the squareness between X and
Y axes.
▪
Measuring point
: both ends and center of straight edge
