Which risk increases when using CBN grinding wheels at excessive speeds?

A)Excessive thermal cracking of workpiece
B)Increased wheel bondline corrosion
C)Higher spindle motor energy consumption
D)Elevated coolant system bacterial growth

💡 Explanation

Excessive speeds cause increased friction, therefore localized heating of the workpiece exceeds critical temperatures, which introduces thermal shock via **heat conduction**, leading to cracking rather than plastic deformation because CBN is extremely hard.
