In order to reduce the error caused by the thermal deformation of the process system during the machining process, it is generally necessary to fully cool down to reduce the temperature rise; The machine tool is processed under thermal balance; Precision machining is carried out under constant temperature. Before processing, all parts must be preheated by idling for a period of time, and then processed after reaching the thermal balance state. Because the influence of thermal deformation on the machining accuracy of precision machine tools is more obvious. Due to the large volume and mass of the machine tool, it takes a long time to reach the thermal equilibrium state from the beginning of temperature rise to its temperature basically unchanged. During the heating process, the machine tool continues to deform, and it is difficult to control the processing size of the workpiece.
