2. Grinding wheel - Wikipedia

   en.wikipedia.org/wiki/Grinding_wheel

   Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface. Trueing the wheel makes the grinding surface parallel to the ...

3. Bench grinder - Wikipedia

   en.wikipedia.org/wiki/Bench_grinder

   The typical wheels on most bench grinders are vitreous-bond wheels. They work best to do their intended task, but they inherently have a risk of cracking. Grinding wheels designed for steel are not to be used for grinding softer metals, like aluminum. The soft metal gets lodged in the pores of the wheel and later expands with the heat of grinding.

   The tolerances that are normally achieved with surface grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [4] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.
