When mounting a grinding wheel, soft pads are used on what parts of the wheel?

Explanation:
Soft pads (blotters) go on the sides of the grinding wheel where the flanges clamp the wheel. They cushion the wheel and spread the clamping force so the wheel seats evenly and doesn’t crack or become damaged from direct metal-to-wheel contact. Placing pads on both sides helps absorb minor misalignment and reduces vibration, keeping the wheel balanced and safe during operation. Avoid placing pads on the grinding face, hub, or spindle—pads are specifically used between the wheel and flanges on the sides.
