← TechnologyWhich outcome occurs when the grinding wheel saturates excessively during CBN grinding of hardened steel?
A)Increased surface finish roughness✓
B)Decreased thermal cracking defects
C)Enhanced material removal rate
D)Minimized wheel wear and damage
💡 Explanation
Increased surface roughness occurs because excessive grit saturation of the grinding wheel prevents effective cutting, therefore a rougher surface is produced rather than a smooth one because the abrasive particles no longer effectively shear the material.
