(5) When the specified parallelism for the scale
mounting bracket is not obtained
Insert spacers below the feet and make adjustment by
placing a dial gauge at 2 in Fig. 3-7 to adjust the
parallelism to within 0.15 mm (0.006") throughout the
length between may be obtained at the alignment marks.
For scales equipped with a center foot plate (effective
length 1,250 to 1,600 mm (49.21 to 62.99 inch)), make
sure that the parallelism near the center foot plate is also
within 0.15 mm (0.006").

3-4-2. Mounting of the slider
(1) When parallelism and flatness of the mounting
surface are already satisfied
When the mounting surface is finished and its
parallelism and flatness satisfy the specifications
below, just mount the slider using two M4×14 hex
socket head cap screws and two plain washers (S).
The mounting dimensions differ depending on the
clearance between the B and C surfaces.
Flatness of C surface
Parallelism of C surface to
machine table movement
Parallelism between B
and C surfaces
Clearance between B and
C surface
• If clearance between B and C surfaces is set to
between 8.7 and 8.9 mm
Move the machine table till the mounting surface comes
just at the slider. First use the spacers provided to fill the gap
between the mounting surface and slider, and then secure
the slider. Then remove the screws which fix slider holder.
(If the gap is still not filled, check the gap between the B
and C surfaces and adjust it is necessary.)
