← TechnologyWhich outcome increases when thermal expansion constricts coolant flow to a grinding wheel?
A)Workpiece surface oxidation flaws✓
B)Precise dimensional tolerance control
C)Extended grinding wheel lifespan
D)Improved swarf removal efficiency
💡 Explanation
Surface oxidation flaws increases excessively from constrained coolant. Thermal expansion reduces flow initiating thermal runaway, because the **boiling crisis** prevents effective heat removal, therefore extreme surface temperatures exceed oxidation limits, rather than maintaining expected conditions with optimized heat transfer.
