Grinding tips
Efficient grinding is achieved by controlling the
pressure and keeping the angle between wheel
and workpiece at 10° to 15° (Fig.10). 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
slow grinding action and put dangerous
stresses on the wheel.
When grinding with a new wheel, be certain
to grind while pulling tool backwards until the
wheel becomes rounded on its edge. New
wheels have sharp corners, which tend to "bite" or cut into work piece when pushing forward.
