Leveling & Mounting; Assembly - Southbend SB1063 Owner's Manual

Model SB1063
Leveling & Mounting
Although not required, we recommend that
you level your machine and mount it to the
floor. Because this is an optional step and floor
materials may vary, mounting hardware is not
included.
We strongly recommend securing your
machine to the floor if it is hardwired to the
power source. Consult with your electrician to
ensure compliance with local codes.
Leveling
Leveling machinery helps precision components,
such as bed ways, remain straight and flat
during the lifespan of the machine. Components
on an unleveled machine may slowly twist due to
the dynamic loads placed on the machine during
operation.
For best results, use a precision level that
is at least 12" long and sensitive enough to
show a distinct movement when a 0.003" shim
(approximately the thickness of one sheet of
standard newspaper) is placed under one end of
the level.
See the figure below for an example of a high
precision level.

Bolting to Concrete Floors
To prevent the Model SB1063 from tipping
and causing a crushing hazard when heavy
workpieces are mounted off-center, we strongly
recommend that you bolt the mill to a concrete
floor or pad.
There are many different methods of securing
the mill to the floor. Lag shield anchors and lag
bolts are available in the sizes required for this
mill. Also, cutting the floor and pouring footings
with embedded J-bolts is another method.
Research options and select the best choice that
fits your specific conditions.
Note: This machine has an oversized electrical
box with a control arm mounted to the top. Below
the electrical box are two additional support legs
(see Figure 13). These adjustable legs are only to
be used as supports and should not be fastened to
the floor or be used as jack bolts to help level the
mill.

Assembly

This machine has been fully assembled and
tested at the factory for break-in and conversion
to CNC operation. No assembly is required;
however, retain the tool box, its tools, and
the manual downfeed handle from the initial
non-CNC configuration. Spindle feed is CNC
operated only.
