Grinding dressers and Wheel Dressers

Grinding dressers or wheel dressers are tools used to dress the surface of grinding wheels.

The purpose of dressing grinding wheels is to minimize vibration and enhance the surface finish. Dressing also dislodges abrasive particles and exposing fresh abrasive from the surface of the wheels. Every abrasive grain of a grinding wheel is in fact is a small cutting tool. When these tiny cutting tools or grains become worn, the grinding wheel loses its effectiveness. Evidence of rounded and worn grains is glazing of the wheel and is obvious when the spinning grinding wheel has a reflective surface.

There are three types of dressers, star dressers, diamond dressers, and dressing sticks. Star dressers are long handled tools that have a row of free running hard and serrated discs that run at right angles to the handle. The following dressers are diamond dressers, which are shorter handled tools that have either a single diamond or diamond matrix on the broad surface of the dresser. Finally, there are dressing sticks, which are composed of a hard material usually silicon carbide with a stronger bonding agent.
