Studying and design the equipment system evaluating the quality of CNC machine tool spindle by analysis the vibration according to the total wear criteria

Abstract

Generally, characteristic of spindle - vibration is considered as an important
parameter to evaluate condition of the machine during operation, However, there is
currently no standard to evaluate the performance of the spindle bearing cluster via
vibration. Based on the structure, function of the spindle, analysis of the wear; the
spindle geometry testing standards; standard measurement and analysis vibration on
machine tools; This paper investigates, builds and integrates the equipment system
to assess the quality of the CNC lathe spindle on the basis of vibration analysis
according to the synthetic wear criteria. Carry out a test of the equipment system to
evaluate the performance of spindle bearing through the vibration characteristics.
The test equipment system results show that the testing process has determined the
correlation between the total axial wear of the CNC machine tool spindle and RMS
when analyzing vibration test results of spindle bearing.
