A precision spindle is manufactured to gage-like exactness and should be handled carefully. Basic precautions should always be taken in preparing a spindle for operation; among these is the simple act of properly lubricating the bearings of the spindle, which is critical to the life of the machine and its performance.
If you’re using an oil-mist lubricated spindle, it is highly recommended that the oil mist be started, either manually or automatically, approximately 10 minutes prior to the start of the spindle. This allows sufficient wetting of the balls and raceways. Spent oil should be present at all of the vents and around the end caps. Additionally, it is highly recommended that the oil mist be allowed to operate for a period of 10-15 minutes after the spindle is shut down. This serves to act as a purging action to prevent the ingress of contaminants as the spindle cools down.
Similarly, if you’re using an oil-air lubricated spindle, allow the lubricator to run for 5-10 minutes and observe the vents and end-caps at the spindle. There should be air and oil present at these points. Once the presence of air and oil has been verified, begin running the spindle. The temperature of the spindle should be monitored closely for the first hour of operation as a safety precaution.
Attention to proper setup and operation should result in a spindle that reaches its rated life-cycle. The cost to replace a high-quality spindle due to failure from overheating or wear should serve as ample incentive to owners of our spindles to require that operators always observe these basic recommendations.
