maximum safe operating speed is not
exceeded by the nameplate speed of the

DISC GRINDING WHEELS
Grinding wheels should be carefully selected
in order to use the grinder most efficiently.
Wheels vary in type of abrasive, bond,
hardness, grit size and structure. The correct
type of wheel to use is determined by the
job. Use disc grinding wheels for fast
grinding of structural steel, heavy weld
beads, steel casting, stainless steel and

Grinding Operations
Efficient grinding is achieved by controlling
the pressure and keeping the angle between
wheel and workpiece at 10° to 15°. If the
wheel is flat, the tool is difficult to control. If
the angle is too steep, the pressure is
concentrated on a small area causing
burning to the work surface.
WARNING
!
grinding action and put dangerous stresses
on the wheel.
When grinding with a new wheel be certain
to grind while pulling tool backwards until
wheel becomes rounded on its edge. New
wheels have sharp corners which tend to
"bite" or cut into workpiece when pushing
forward.
