Linear Way L

Mounting methods of attendant track rail
The following methods may be used to mount the attendant track rail. Select the method most suited to the
specifications of the machine or equipment.
1 Use of reference mounting surface
Firmly push the reference mounting surface of the track rail against the reference mounting surface of the bed
using a pressure plate or small vise. Fix the track rail by tightening the mounting bolt at the position of the
pressure plate or vise. Tighten the mounting bolts one by one starting from one end of the track rail to the
other.
2 Use of mounted datum track rail as the reference
Fix the datum track rail correctly, fix one attendant slide unit correctly in the direction of motion, and
temporarily fix the other slide units and the attendant track rail. Then, fix the attendant track rail by tightening
the mounting bolts one by one from one end of the track rail to the other while checking the smooth
movement.
3 Use of straight-edge
After fixing the track rail temporarily, apply the indicator probe to the reference mounting surface of the track
rail (as shown in Fig. 44). While checking the straightness in reference to the straight-edge, fix the attendant
track rail by tightening the mounting bolts one by one from one end of the track rail to the other.
4 Use of datum side Linear Way
As shown in Fig. 45, set an indicator
stand on the top face of the datum
slide unit and apply the indicator probe
to the reference mounting surface of
the attendant track rail. While checking
parallelism of the two rails, fix the
attendant rail by tightening mounting
bolts one by one from one end of the
track rail to the other.
