CNC Spindle Maintenance and Troubleshooting Handbook
Direct answer: Daily taper cleaning, correct warm-up, air and coolant checks, vibration monitoring, drawbar inspection, and VFD alarm review prevent many spindle failures. Stop the spindle when abnormal noise, temperature, tool pull-out, or uncontrolled vibration appears.

| Daily | Taper, holder, air, coolant, and warm-up |
