How to Diagnose and Correct Spindle Speed Abnormalities in CNC Machining Centers?
Many operators may panic in such situations—either repeatedly adjusting parameters or blindly replacing components—resulting in unresolved issues and wasted production time. Diagnosis should follow a path from simple to complex, from external to internal, gradually checking electrical, mechanical, and control systems, using alarm messages and measurement tools to locate the root cause. Correction should target the fault through component repair or replacement, parameter adjustment, or optimization of external conditions to restore proper spindle speed.
