How to Dress a Grinding Wheel (Fast and Easy Way)
Now to the core of the dressing process: rest the tool on the guard and move in back and forth across the spinning wheel, until you get a flat surface on the wheel. This step is the same for whatever tool you decide to use. After dressing the wheel, re-adjust the guard so it is positioned 1/16 of an inch (or a couple mm) from the wheel.
Grinding Operation - an overview | ScienceDirect Topics
The abrasive particles of the wheel with the softer grade would preferentially be pulled off rather than rupturing the surface and causing clogging of the grinding wheel. This is, in effect, a continuous process of self-dressing of the grinding wheel, thus ensuring that the surface of the grinding wheel always has sharp, fresh abrasive particles.
