Preventive Maintenance Can Prolong Life of Fanuc Spindle Motor

Today’s machine tool spindles are faster and more complex, and the costs associated with repairs are increasing. To help prolong the life of your Fanuc spindle motor, preventative maintenance of your machine’s spindle is key. At TIE, we’ve seen all types of damage from the drive keys being completely sheared off the shaft, overheating, corrosion and more. These motors often operate in a dirty environment and severely contaminated bearings are the most common cause of spindle failure.

Other causes include: crash/impact damage due to human error, lack of lubrication, machine vibration, programming mistakes, misaligned tool, or fixturing that has been mounted incorrectly.
