The rail that has been tightened can now be used as a reference rail. Using a vernier calipers
or other accurate tool, measure the distance between the two rails, and adjust each end until
they are the same. Tighten a bolt snugly at each end of the rail.
The next step is to install the table,
and to use the table to align the
rails.
Firmly bolt the table to ball slides 1 and
2 on the firmly secured rail as shown in
the diagram. Then position ball slide 3 at
the left end of the adjusting rail, and bolt
the table to this ball slide. Move the ball
slide 3 to right and bolt the table to the ball
slide 4.
Move the table to one end of the rails,
and start tightening the adjusting rail
bolt sequentially to the specified torque
while checking excessive friction of table
movement. Continue moving the table
down the rail tightening each adjacent
bolt until they have all been tightened.
This method of assembly is for general industrial machinery where smooth linear motion is the
overall objective. When precision accuracy is required, read on to the following procedure.
