Grinding with the Grinding
Wheel
WARNING: The grinding wheel can fly
apart and cause injury.
Grinding wheels must always be
checked for cracks or imperfections.
This is done with the “ring test”. Tap
the wheel gently near the outer rim
with the handle of a screwdriver. You
should hear a clear bell-like ring. If
a dull thud occurs, do not use the
wheel. The wheel may be damaged
and could come apart during opera-
tion.
Bring the workpiece into the wheel
1.
gently, without jarring.
When grinding high speed steels
2.
such as drill and tool bits, avoid high
temperature buildup as this can affect
the temper of the steel.
For small workpieces such as drill
3.
bits or chisels, avoid applying pres-
sure to the wheel at a high angle that
could cause the workpiece to become
lodged between the tool rest and the
wheel.
