Cylindrical Grinding - Fine MetalWorking

Cylindrical Grinding is a process where you use a grinding wheel rotating in a horizontal axis to cut or grind a cylindrical work-piece mounted on a chuck or between centers rotating in an axis parallel to the grinding wheel axis, in the same plane. Abrasive particles on the grinding wheel do the cutting of material.

grinding wheels - Sizes

grinding wheels. Grinding wheels consist of abrasive particles bonded by some other substance, which may be anything from rubber to a kind of glass. The bond is meant to fail. As a particle becomes worn, the drag on it increases and friction makes it hotter, just as a plane with a dull blade requires more force than one with a sharp blade.
