← TechnologyWhich risk increases during high-speed internal diameter (ID) grinding of hardened steel bearing races?
A)Thermal stress induced micro-cracking✓
B)Electrolytic corrosion from coolant breakdown
C)Vibrational resonance in grinding spindle
D)Abrasive grain buildup on wheel
💡 Explanation
Micro-cracking risk because of high thermal stress increases from rapid heating and quenching cycles within the localized cutting zone, driven by frictional heat. Localized thermal expansion exceeds the material's yield strength, therefore causes cracks rather than only plastic deformation.
