Mounting the Master LM Rail

Using a Temporary Reference Surface
You can use a reference surface provided near the LM
rail mounting position on the base to achieve straight-
ness of the LM rail from the rail end. In this method, two
LM blocks must be joined together and fixed to a mea-
surement plate, as shown in Figure 4-15.

Using a Straight-edge
After temporarily fastening the mounting bolts, using a
straight-edge as a reference as shown in Figure 4-16,
use a dial gauge to check the straightness of the side
reference surface of the LM rail from the rail end, and at
the same time, fully fasten the mounting bolts.
To mount the subsidiary LM rail, follow the procedure
described on p. 4-3.
