Internal grinding is a three-dimensional hole-finishing method, accounting for 27% of all machine-tool operations on average (and up to 70% in some specialties). Internal grinding must meet high standards in terms of precision (quality class 5–6 for the diameter) and surface quality (surface roughness R a = 0.06–2.5). Most often CNC ...
The rate of metal removal in internal grinding must be decreased solely in order to decrease the cutting force, which directly affects the machining precision, the thermal defects, the surface roughness, the blunting of the abrasive grains, the wheel's radial wear, and other factors.
