High-precision machine tools are important equipment of production line in general . However, it is too
difficult to do failure prediction and maintenance of the spindle bearings. Equipment utilization will be decreased if the
damaged bearing is not replaced in time. This paper designed a set of bearing failure prediction system based on
LabVIEW programming environment, according to the requirement for the maintenance of spindle bearing on production
line. The system will predict the bearing failure through the analysis of the size precision of the parts. The system mainly
consists of two parts, data acquisition system and data analysis system. It achieves the following functions: data analysis
and calculation, data display and storage, system failure alarms, etc.
