Caution: A work part shall be mounted on a machined plane or a plane with equivalent precision,
and the flatness shall be 0.01 mm/m or less. If sufficient flatness is not secured, the table
is deformed when mounting and fixing a work part, causing malfunction.
Flatness refers to the height difference between the maximum value (peak) and
minimum value (trough) of surface distortion.
The length of screws used to mount a work part must the effective screw depth
described here or less.
If a screw is screwed in more than the effective screw depth, the end may get into
