Floor Condition: Crowned
The flatness of the floor plays an important step in the leveling
procedure of the machine. To properly level the machine the
weight bearing points must be as far from the centerline of the
machine frame as possible.
Should a condition known as crowning exist the weight bearing
points of the machine may not be far enough from the machine
centerline to ensure a stable machine.
Under these conditions, a procedure known as Half-Shimming
should be used.

To move the weight bearing points further from the machine
centerline the use of half-shims of .125" thick on top of the base
plate as shown is recommended.
After the half-shims are installed and the machine frame is
leveled, use the rocking test to determine that the machine frame
is stable enough to allow production without damaging the
machine.
Under extreme conditions the use of half-shims may not move
the machine weight bearing points far enough from the machine
centerline to ensure the machine frame is stable.
Under these conditions, a more suitable location must be found
for the machine, or a new foundation for the machine will be
necessary.
