③ Runout : Result of deducting the smallest value from A, B, C and D from the
▪ Tolerance: 0.013mm
3) Correction
Perform the measuring on pallet 1 and pallet 2 and decide which one you should correct.
(1) A, B, C, D: If pallet 1 and pallet 2 show similar results in height distribution, grind the
liner of the table locating pin for the correction. If the results are different, remove the
liner from the locating cup and grind it as necessary.
(2) 1, 2, 3, 4 : If a tilt is found in the Z axis direction (if A is similar to B; C is similar to D,
and A is significantly different from D; B is significantly different from C), use the level
bolt (APC side) on the front X axis to move the axis up/down for the correction. If a
tilt is found in the X-axis direction, perform the scraping of the sliding plate under the
table again.
※ Adjusting the table locating pin liner and the pallet locating cup liner
① Refer to "Parallelism of Pallet Deck" above in this manual to measure the
parallelism.
② Calculate the grinding size of the liner based on the measurement.
③ Loosen the bolts on the locating cup. (Loosen the bolts on the locating pin, if this is
the case.)
④ Insert M8 bolts (x2) into the tap hole (used for the lifting work) of the locating cup and
tighten them slightly until you can remove the liner. (For the locating pin, use the pin
puller to lift it up slightly)
⑤ Remove the liner and grind it based on the calculation "②" above. Then, install it
back to the original.
⑥ Tighten up the bolts for the locating cup or locating pin. (For the locating pin, use the
pin puller or other similar tool to impact on the center bolt place in advance.)
⑦ Measure the parallelism again and repeat the steps above until you get a
satisfactory result.
