Conditioning of grinding wheels The conditioning of a grinding wheel serves for regeneration by dressing (profiling / sharpening) or cleaning. Conditioning takes place both before the first treatment and after the grinding wheel has worn out unevenly due to the treatment. Conditioning can be divided into two forms: dressing and cleaning.

The ElectroChemical Grinding wheel is a matrix of abrasive particles and copper powder held together by a resin bond. The copper makes the grinding wheel conductive while the abrasives serve to remove the metal oxides from the work piece. The small cavities between the abrasive grains serve as a galvanic cell to facilitate the electrolytic process.

Electrochemical dressing (ECD) is a technique able to sharpen grinding wheels by means of an electrochemical dissolution process of the metallic grinding wheel bond. This dressing process is controlled by the electrolysis process itself or by monitoring the grinding process.

The conditioning of a grinding wheel serves for regeneration by dressing (profiling / sharpening) or cleaning. ... In the case of a single grain diamond, the dressing tool is guided along the grinding wheel during the dressing process so that the abrasive grains break out of the grinding wheel. The correct angle of between diamond and grinding ...

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 guardso it is positioned 1/16 of an inch (or a couple mm) from the wheel.
