4. An undamaged grinding wheel will emit a
clear metallic ring or “ping” sound in each of
these spots. A damaged grinding wheel will
respond with a dull thud that has no clear
tone.
— If you determine from ring test that grind-
ing wheel is damaged, DO NOT use it!
Wheel Dressing
Depending on the type of grinding you do, the
grinding wheel may require periodic dressing.
There are several different types of wheel dressing
devices available on the market (see
Page 22 for
an example). Dressing restores the abrasive qual-
ity of the wheel surface and brings the wheel edge
back to a square form.
Refer to the instructions that accompany your
dressing accessory for complete details on how
to properly dress the wheel.
Always adjust tool rest and spark deflector
after dressing or replacing grinding wheel.
Failure to do so could lead to workpiece
kickback and injury.
ALWAYS visually inspect and perform a
“ring test” on a wheel before assembly. DO
NOT use damaged wheels!
