Tips to Extend Spindle Life | Fabriing and Metalworking

Apr 25, 2012· The ingress of coolant through the spindle seals, labyrinth, or covers must be avoided. The coolant can wash out the grease or oil from the bearings and attack the spindle’s shaft, motor, and electronics. The lesson is to keep the coolant directed at the tool and away from the spindle. This will give you the best chance for long spindle life.
