2. 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.

3. 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 ...

4. Grinding machine - Wikipedia

   en.wikipedia.org/wiki/Grinding_machine

   As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications, it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field.

5. Tool and cutter grinder - Wikipedia

   en.wikipedia.org/wiki/Tool_and_cutter_grinder

   The operation of this machine (in particular, the manually operated variety) requires a high level of skill. The two main skills needed are understanding of the relationship between the grinding wheel and the metal being cut and knowledge of tool geometry. The illustrated set-up is only one of many combinations available.
