10.7 Squareness in division of index table
1) How to measure
(1) Place the square horizontally on the pallet
deck. While moving the X axis, correct the
parallelism between square and X axis.
(2) While indexing the B axis, perform the
clamping so that the square should not
move.
(3) While indexing the B axis totally 4 times,
one for each 90 degrees, measure the
parallelism totally 4 times accordingly. The
greatest difference is the measurement.
▪ Tolerance: 0.012mm/300mm
2) Correction
As the angle division of the index table is performed using the precise curvic coupling, it
is unlikely to make an error. However, if you encounter a significant error, that's because
the curvic coupling inside the table is contaminated with dust and impurities, or it is
defective, damaged, or worn out. If this is the case, clean inside the table or replace the
curvic coupling with a new one.
