2. Apply minimum pressure to work surface,
5˚–10˚
FIG. 15
allowing the tool to operate at high
speed. Material removal rate is greatest
when the tool operates at high speed.
3. Maintain a 5˚ to 10˚ angle between
the tool and work surface for wire cup
brushes.
4. Maintain contact between the edge of the wheel and the work
surface with wire wheels.
5. Continuously move the tool in a forward and
FIG. 16
back motion to avoid creating gouges in the
work surface. Allowing the tool to rest on the
work surface without moving, or moving the
tool in a circular motion causes burning and
swirling marks on the work surface.
6. Remove the tool from the work surface before turning the tool off.
Allow the tool to stop rotating before setting it down.
CAUTION: Use extra care when working over an edge, as a
sudden sharp movement of grinder may be experienced.
