〈1〉 When the mounting surface already meets
parallelism and flatness requirements
When the scale mounting surface is finished and meets the
parallelism and flatness specifications below, just mount
the scale. (For scales of L<1050 mm/41.34", use two
M4×10 hex socket head cap screws and two plain washers
(large); for scales of L≧1050 mm/41.34", use three M4×10
hex socket head cap screws and three plain washers
(large). Tightening torque: 350 N·cm/35 kgf·cm)
Flatness of A, B surfaces
Parallelism of A, B surfaces to
machine table movement
Provide the range shown in Fig. 3-5 for surface A.
The above tolerances suppose no quick change in the
48
surfaces and no obstacle in the way between the right and
left mounting surfaces.

〈2〉 When the scale mounting surface is a casting
surface
Mount the scale using mounting brackets
(1) When the scale mounting surface is a casting
surface and parallelism is not satisfied
Use mounting brackets and adjust so that the
parallelism specified in 〈1〉 may be satisfied.
The mounting brackets need only cover the length of at
least the scale feet. However, the brackets must be
long enough for the parallelism of the right and left feet
of the scale to be measurable.
