GRINDING FLYWHEEL
MANUAL MACHINES:
Feed grinding wheel downward by turning feed handle
clockwise (Figure 22). Grind surface until flat and free of
defects or to desired depth.
POWERHEAD MACHINES:
1. Power the grinding head down to the work piece using the
power column up/down switch (as a safety feature, the
power column will not function if the grinder motor is
running).
2. Start table, grinder head motor, and coolant flow.
3. Rotate the fine feed hand knob clockwise (Figure 23) to
lower grinder head until stone contact is made. (if machine
is equipped with the auto grind feature, proceed to step 4)
Continue to feed grinder head down to grind surface until
flat and free of defects or to desired depth.
4. This step is for machines equipped with auto grind only:
a. Determine depth of grind (amount of material to be
removed).
b. Rotate graduated dial to that amount lined up with
pointer (Figure 24)
c. Select the down feed rate with the variable feed rate
dial.
d. Start to auto grind by depressing the “on” switch.
e. Auto grind will stop feeding and turn off when the preset
depth is reached (feed may temporarily stop as it
senses the grinder motor being overloaded and then
restart automatically during the auto grind process until
finished).
f. Turn off table, grinder head motor, and coolant after the
work piece sparks out.
SURFACE FINISH:
Keep the grinding wheel cutting at all times never allow the
wheel to coast for a long period of time without feeding it downward. Long periods
of coasting will cause the grinding wheel to glaze and load up. The only exception
to this is when it is desired to obtain a very smooth finish. A wide variety of surface
finishes are obtainable using the grinder without varying the grit size of the
grinding wheel. This range of surface finish is obtained by varying the pressure
exerted on the grinding wheel. A coarse finish is obtained by feeding heavily then
backing off the work piece quickly. Smoother finishes are obtained by backing off
the work piece then coming back down with a very light feed pressure.
