Why is Spindle Vibration Dangerous?
High-speed spindle motors in CNC milling and router machines require micron-level precision. Abnormal humming, loud noises, or visible vibration ruin the surface quality of the machined part and lead to broken cutting tools.
Main Causes of Vibration
Causes include worn-out high-speed ceramic bearings, rotor unbalance due to sudden impacts or tool collisions, and electrical imbalances transferring into mechanical vibrations.
Dynamic Balancing and Overhaul
Ignoring the vibration can snap the spindle shaft. Code Elektronik replaces worn bearings with original high-precision variants (SKF, FAG, NSK). After repair, the motor undergoes computerized dynamic balancing to eliminate vibrations before delivery.
