    For warm-up, run the spindle at 9,000 rpm for 10-15 minutes or until the spindle bearing supports reach 98º F (human body temperature). This allows bearings, bearing supports and the spindle shaft to reach their designed dimensions and preloads through thermal expansion. Applying loads to a cold spindle will cause premature bearing failure.
