Resetting the locating push position
The locating pin or bush may be mis-positioned
from the B-axis reference point or from the right
angle (0
˚, 90˚, 180˚, 270˚) due to such as an
impact on the table. Even if they are correctly
positioned from the reference point or each right
angle, performing the locating will move the
table accordingly.
(1) Pull out the positioning pins (2-SPB 10X50)
from the problem-making locating bush and
loosen the bolts (6-BB12×30).
(2) Refer to "Resetting the reference point for
the B axis" above to set the exact
reference point for the table.
(3) Perform the table locating.
⇒
The locating bush in the table will take
place in the locating pin position.
(4) Tighten up the locating bush fixing bolts (applicable bolts only)
(5) Perform the table unlocating and turn the table to tighten up the bush bolts. Then,
reset the B-axis reference point before performing the table locating to check if there
still occurs an interruption.
(6) While indexing the B axis by each 90
˚, correct t
he positions of the other three
locating bushes respectively.
(7) When done, place the square horizontally
on the table deck. While turning the X axis,
adjust the parallelism between X axis and
square. Clamp the square to the table so
that it does not move when indexing the B
axis. While indexing the B axis by each 90
˚,
measure the parallelism of the X-axis
direction to check if the error of division
squareness falls below the tolerance.
