Collapsed Bearings on Bridgeport VMC800
The X axis was immediately tripping out on this 1998 Bridgeport VMC800 when trying to reference we were called in as the customer suspected the faults were caused by a faulty servo drive or servo motor.
The motor passed the insulation and balance tests and the servo drive passed the diode check, so we had to dig deeper.
The next stage was to remove the motor and try and jog the axis. The motor moved freely, but the ballscrew was locked solid.
On closer inspection, we found the bearings had collapsed. New bearings were ordered and this 22 year old machine will live to see another day.
Quite often, faults can be deceptive. It initially appeared that the root cause was an electrical issue, but a few simple tests uncovered a mechanical failure causing the servo drive & motor to overload.

A common failure on Siemens and Heidenhain-controlled CNC machines such as XYZ, Hardinge, Bridgeport, Breton and Dugard is E/R module failure.
Over time, the internal fans stop working and coolant and contaminant ingress occurs. The most common failure type we see is the 16/21 KW (6SN1145-1BA01-0BA1(2/0).
