3) Shaking of the table
①
Measure
Install the indicator at the end of the spindle
and place the height measuring block
500mm away from the table center in the X
and Z directions before setting the reference
point ("0"). Then, rotate the B axis by each
90
˚ and measure the difference.
▪
Measuring point
: If the table center is set as "0"
From "X500.Z500", rotate the B axis by
each 90
˚ four times to measure 4 points
▪
Tolerance: 0.025mm
②
Correct
The shaking of the table is caused by a
problem with the parallelism between table
bottom and deck. So if you want to correct
the shaking, you should scrape the bottom
or grind the deck as appropriate.

15.7 Squareness in division of index table
1) How to measure
(1) Place the square horizontally on the table
deck. While moving the X axis, correct the
parallelism between square and X axis.
▪
To correct the parallelism, use the handle
of a screwdriver to impact on certain points
of the square.
(2) While indexing the B axis, clamp the square
to the table lest that it should move.
(3) While indexing the B axis totally 4 times, one for each 90 degrees, measure the X-
axis parallelism totally 4 times accordingly. The greatest difference is the
measurement.

Measuring point: 0
