Abstract
Experimental studies of the temperature of the working fluid in the spindle bearings of the grinding head of circular grinding machines of different models have been performed. The conditions of the performed experimental researches are described. The influence of ambient temperature and design parameters of grinding head parts on the change of working fluid temperature in the front and rear spindle bearings is considered. It is experimentally proven that the difference in fluid temperatures in the front and rear bearings depends on the operating time of the machine. The time interval of machine operation when thermal equilibrium occurs is set.
