Which risk increases when the spindle oil viscosity degrades?

💡 Explanation

Increased hydrodynamic bearing metal contact occurs because viscosity is essential for maintaining the fluid film. Therefore, degraded viscosity decreases the fluid film thickness between components, which directly increases the contacting surfaces, rather than alternative outcomes like tool integrity.
