Test and Analysis of Machine Center's Principal Spindle Thermal Characteristics

Abstract

The significance and present situation of machine tool's thermal characteristics test technology is expatiated first. Aiming at certain three-axis vertical machine center's mechanical principal spindle, thermal characteristics test is done when principal spindle's temperature is rise and fall. Spindle thermal error analyser is used to test machine center's thermal errors in X, Y and Z directions and monitoring temperture of spindle. The spindle's temperture and thermal errors are presented and the test results are analyzed at last. The machine center's thermal information are mastered through test data and analysed results.
