Setting Spindle Speed
The Model SB1024 uses a variable pulley system
to set infinite speeds within the speed range
selected. The Model SB1025/SB1026 requires
re-positioning the V-belt on the pulleys to change
spindle speed.
Use the appropriate section below for the mill to
select the correct spindle speed.
Setting SB1024 Spindle Speed
1.
Start the spindle rotation.
2.
Slowly rotate the speed handwheel shown
in Figure 34 until the desired speed is
displayed in the speed indicator window for
the speed range selected.
For the Model SB1024 ONLY, always make
sure that the spindle rotation has been started
and is at a constant speed before using
the variable speed handwheel to adjust the
spindle speed. Otherwise, the moving parts
inside the belt housing could be damaged and
void the warranty.
