SPINDLE BEARING MONITORING USING ACOUSTIC EMISSION

• Abstract:

  A premature failure of machine tool spindle bearings is a major problem in production and can result in enormous loss in the production and spindle rehabilitation cost. This paper describes a condition monitoring system applied to the spindle of a NC machining centre. During idle run the acoustic emission and vibrations were measured using sensors installed in prepared places. A large number of tests were carried out with varying sensor location, spindle rotating speed and spindle load. Measurements were performed in real industrial environment nine times with six weeks intervals in order to obtain trends. The spindle run out was determined at every measurement time as well.
