① from the workpiece hole size of the wheel diameter, speed is not very high, so greater surface roughness of bore grinding.

② small diameter of the grinding wheel axis, hanging out, poor rigidity and deformation and vibration, and should not be based on a larger grinding depth and feed rate and low productivity.

③ grinding contact gang area, grinding heat, easy to burn the workpiece.

④ poor cooling conditions, difficult chip, clogging of grinding wheel. Therefore, the wheel wears out quickly, require constant repair and replacement, increased time.

Therefore, the foot hole quality and efficiency rather than cylindrical grinding. But good adaptability in hole, particularly suitable for grinding scold hard holes, blind holes, etc.
