Which risk significantly increases when exceeding finish cut tolerances on a CNC lathe threading operation?

A)Elevated tool bit micro-chipping

B)Premature spindle bearing degradation

C)Workpiece thread galling tendency✓

D)Increased collet chuck vibration

💡 Explanation

Workpiece thread galling increases because exceeding tolerances during threading causes surface roughness, leading to greater friction via adhesive wear: the threads seize. Therefore, galling susceptibility is elevated, rather than only tool wear or vibrations.
