Linear Way L

Mounting methods of datum track rail
The following methods may be used to mount the datum track rails of Linear Way and Linear Roller
Way. Select the method most suited to the specifications of the machine or equipment.
1 Use of mating reference mounting surface of bed
Firmly push the reference mounting surface of the track rail against the mating reference mounting surface of
the bed using a small vise or clamp. Tighten the mounting bolt at the position of the vise. Fix the track rail by
repeating this procedure from one end of the rail to the other in succession.
2 Use of a temporary reference surface
Prepare a temporary reference surface
near the mounting surface of the bed
and temporarily fix the track rail. Next,
fix an indicator stand on the top face of
the slide unit as shown in Fig. 43. Apply
the indicator probe to the temporary
reference surface and fix the track rail
by tightening the mounting bolts in
succession from one end of the track
rail to the other while checking the
straightness of the slide unit movement.

3 Use of straight-edge
After temporarily fixing the track rail,
apply an indicator probe to the
reference mounting surface of the track
rail as shown in Fig. 44. Tighten the
mounting bolts one by one, while
progressively checking the straightness
of the track rail in reference to the
straight-edge from one end of the track
rail to the other.
