Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

However, finish boring or internal grinding may perform this task, but spindle deflection, variation in the harness of the material, and difficulties in precise work-holding make the result unperfect and slow the work. Honing, on the other hand, uses rectangular grinding stones rather than circular grinding wheels to eliminate these irregularities.
