CHAP. 5 GRINDING OPERATION

5.1 MOUNTING, DISMANTLING AND BALANCING
GRINDING WHEEL
5.1.1 MOUNTING AND REMOVING THE GRINDING WHEEL:
1. When mounting or removing the grinding wheel, an extracting nut shall be applied for removing or
mounting the grinding wheel with flange.
2. Before mounting the grinding wheel, it is necessary to check the grinding wheel condition, and
clean the spindle taper surface and the tapered hole of the flange. Fit the grinding wheel to the
spindle, then tighten the grinding wheel lock nut (A) by turning it counter-clockwise (Use an wrench
for slight tightening without need of forced tightening, because the grinding wheel lock nut (A) will
tighten further when the spindle is running clockwise).
3. Before removing the grinding wheel with flange, you need to remove the grinding wheel lock nut (A).
Turn the grinding wheel extracting nut (C) into the flange until it touches the spindle, then apply an
wrench for turning it clockwise which enables the flange to separate from the spindle. Now you can
take out the grinding wheel.
