The significant difference between cylindrical grinding of internal & surfaces is the Wheel to Work conformity. In Internal grinding, on account of grinding of internal surfaces the arc of contact and thereby the conformity between the wheel and work-piece, is substantially higher.In Internal Grinding, high Wheel-Work conformity results in
Large number of grains in contact with the work-piece > Lower Force per unit grain
Grain and bond fracturing gets hampered due to low Force per grain and can lead to more rubbing and sliding of the abrasive while grinding (Glazing)
Poor coolant availability in the grinding zone
The work material debris (chips) have a higher probability to be entrapped between the wheel and the work, leading to their increased frictional effect
High heat generation due to poor lubricity, higher friction and iability to remove heat effectively from grind zone
