3. A grinding wheel in good condition will give
a clear sound at any tap point. If it does not,
the wheel is damaged. Do not use
damaged wheels.
4. Place a grinding wheel onto the shaft of the
grinding wheel seat (Figure 8).
5. Place the large washer onto the shaft, then
thread the flat nut (left-hand threads; rotate
counterclockwise to tighten) onto the wheel
seat shaft. See Figure 9. Tighten the flat nut
using the provided arbor wrench.
6. To remove a grinding wheel, reverse the
above procedure.
Removing Wheel Assembly
1. To remove the complete wheel assembly,
remove the center nut (left-hand threads)
from the shaft.
2. Thread the wheel extractor into the shaft of
the wheel seat (Figure 9) and pull off the
wheel assembly.
Wheel Dressing
Dressing procedures may vary depending upon
optional accessories.
The diamond dresser seat provided with this
machine must be used with a magnetic chuck or
an overhead dresser system. These last items
are optional accessories and can be purchased
through your JET dealer.
1. Set the diamond in the overhead dresser, or
in the seat on the magnetic chuck. The
collar of the dresser is about 5°. The collar
should be turned a small degree to keep the
cutting edge in sharp condition. Use the
coolant during dressing of the wheel. Start
dressing in the center of the wheel.
2. If the grinding allowance is between .0008
and .0012 inches, the diamond should pass
through the wheel quickly.
3. If the grinding allowance is .0004 inches, the
diamond should pass through slowly.
4. Repeat the process 2 to 3 times until the
wheel is clean and its corners are square.
NOTE: Do an initial dress before balancing the
wheel to make the wheel round and true to the
spindle. After the wheel has been balanced, do
your final dress.
