Abstract

Abstract

To reduce the thermal deformation of a motorized spindle's shaft body and the common faults of important parts such as bearing in the processing center, a real-time thermal error compensation calculation method based on collecting the temperature change of the motorized spindle and the bearing's common fault diagnosis method were proposed. The thermal error compensation calculation method can improve the machining accuracy of the motorized spindle unit through processing the temperature measurement point data of the shaft body. The fault diagnosis method is used to set different thresholds for different temperature nodes. The threshold corresponds to the fault characteristics of a certain important part inside the motorized spindle unit. When the change in a temperature node exceeds the threshold, the alarm is given to diagnose the faults of a particular part.
