Which risk increases when bearing tolerances tighten excessively in high-speed CNC machining?

💡 Explanation

Lubricant film starvation increases because excessive bearing preload amplifies friction, therefore decreasing lubricant effectiveness rather than improving machining or surface quality as the bearing heats via friction via the excessive radial compressive force.
