15.5 Squareness between coordinate axes
1) X – Y Squareness
ⓐ
Measure
Place the square on the table deck in the X-axis direction and install the indicator on
the spindle head. Check the squareness between X and Y axes. The greatest
difference is the measurement.
▪
How to measure : As shown below, set both
ⓑ
and
ⓒ
to "0" and calculate "
ⓑ－ⓐ
"
and "
ⓒ－ⓓ
". If
ⓐ
and
ⓓ
are the same symbol (+/-), add "
ⓑ－ⓐ
" to "
ⓒ－
ⓓ
", if not, deduct the smaller value from the greater one.

Squareness between X and Y can be corrected using the level in the column bed (Z
axis).
(1) Place the square graplate (surface plate) vertically in the X-axis direction and
install the indicator on the spindle head. Measure the parallelism between square
graplate and X axis. Take a note of the difference and direction.
(2) Then, present the indicator to the square graplate in the Y-axis direction and
measure the overall squareness. Take a note of the difference and direction.
(3) Set the bottom of the square graplate to “0” and move up and stop the Y axis at
the top of the square graplate. Tighten the level block evenly on one side of the
column bed. (Generally, the squareness can be approximately corrected by
moving the applicable axis twice as much as the changes to the indicator
gradation.)
(4) Repeat the steps above until you get the satisfactory result.
(5) When done, check the machine level and, if it's not proper, perform the machine
leveling again.
※
Note that the squareness takes priority over the level. So ignore the absolute
level and focus on the feeding level when performing the leveling.
