Why does grinding wheel need to dress?
Dressing. When the sharpness of grinding wheel becomes dull because of glazing and loading, dulled grains and chips are removed (crushed or fallen) with a proper dressing tool to make sharp cutting edges and simultaneously, make recesses for chips by properly extruding to grain cutting edges. Thus, these operations are for the dressing. Trueing.
Why do grinding wheels need washed after dressing?
For your information, a grinding wheel is made of abrasive grains clogged together with a bonded material. After some use, those grains can crack down and become smoother; also, bits of metal can be stuck between them.
