Using Accelerometer Data to Diagnose Spindle Problems
Why Accelerometer Monitoring Matters A spindle failure on a deep hole drilling machine stops everything. The machine is down for days while the spindle is rebuilt or replaced. I use accelerometer-based vibration monitoring to detect bearing defects months before they cause failure, so I can schedule repairs during planned downtime. The accelerometer system cost is about 2000-5000 USD for a single machine. The value is in preventing unexpected spindle failures that cause extended downtime. A single emergency spindle replacement can cost 15,000-30,000 USD in parts and labor plus lost production time. ...
