Balance of grinding wheel
Balance of grinding wheel is to obtain good smoothness and accuracy of workpiece
after grinding and to keep machine in equilibrium condition. The mark caused by
tremble appearing on the surface ofworkpiece is owing to vibration. This kind of
deformation can be seen by eyes. Vibration often occurs when grinding wheel is not
balanced which iscausedby deviation flange mounting on grinding wheel or obliquity
between flange and spindle.
Grinding wheel balancing steps: (show as figure)
1. Mount the blancingarbor (1) into grinding wheel with flange (2) and lock it
tightly with nuts (3) and place it on the balance base.
2.
Rotate the grinding wheel by hand. When it stops, the bottom point is where
with the most heavy weight. And then adjust weight blocks (4). Loosen
fixing screw (5) while adjusting, move weight blocks (4) and fasten fixing
screw (5).
3. By serveral times of adjustment, make the grinding wheel non-stop at the
certain point means get balanced. To mount a new grinding wheel, first
measure its balance in general and then balance is made after the surface of
grinding wheel is completely corrected and dressed. It’s no need to correct
balance of regulating wheel because it rotates slowly.
