Example of Mounting the LM Guide When the Master LM Rail
Is Not Provided with Set Screws
Mounting the Master LM Rail
After temporarily fastening the mounting bolts, firmly
press the LM rail to the side reference surface at the
position of each mounting bolt using a small vise and
fully fasten the bolt. Perform this in the proper order
from one rail end to the other. (Figure 4-9)
Mounting the Subsidiary LM Rail
To mount the subsidiary LM rail in parallel with the correctly mounted master LM rail, we
recommend adopting the methods below.
z Using a Straight-edge
Place straight-edges between the two rails, and arrange
the straight-edges in parallel with the side reference
surface of the master LM rail using a dial gauge. Then,
secure the mounting bolts in the proper order while
using the dial gauge to ensure straightness of the
subsidiary rail axis, using the straight-edge as the
reference. (Figure 4-10)
