Spindle Run-in or Cycle Procedure
Monthly: Perform a spindle run-in before operating the machine if the spindle has been
idle for more than 30 days or if the spindle has never been used.
1. Referring to the appropriate Max RPM Spindle table below, run the spindle for
the indicated time, at the recommended speeds, depending on your maximum
spindle speed. Proceed in the order listed in the table.
2. Monitor the temperature at either the front or upper bearing and either the
rear or lower bearing (depending on the type of machine), both of which
should not exceed 55º C (130º F) once the maximum RPM is achieved.
3. If spindle flange temperature does not exceed 55º C (130º F) at any time
during the spindle run-in procedure, then the warm-up procedure is complete.
4. If spindle flange temperature exceeds 55º C (130º F) at any time during the
spindle warm-up, then stop the spindle immediately. Allow the spindle to cool
to room temperature.
5. Restart the warm-up procedure at the last speed used prior to the
temperature spike.
6. Repeat steps 1-3 above until the spindle runs at each specified RPM for the
time specified, below 55º C (130º F).
