This paper deals with a new experimental approach to analyze radial, axial and tilt error motions of machine tool spindles under load. This work focuses on the identification error of the spindle movements under different machine operation conditions between 500 5000 rev / min and loads in range 50 - 500 N. Errors of the spindle movements are measured on cylindrical workpiece using capacitance sensors for different loads. The analysis of measurements of radial, axial and tilt error motions of machine tool spindle indicates dependence between loads and measured errors. The integration of the error measurements to novel multi-body dynamic models of machine tool spindles is very important for prediction of machine behavior during a cutting process.
