Job Report #1-Fanuc Servo Spindle Motor Modification

spindle job 1

A customer shipped us this Fanuc Spindle Motor for repair and modification, to fit their application.  Jason, the lead Servo Technician at Repair Zone, had to fully disassemble and machine a keyway into the shaft.  Also, he had to machine the end bells and put new bearings on this unit.  Below is the pictorial of the process that took place, which included our machining center lending a hand.  (Above: Heating speed sensor ring for removal during disassembly)
