Abstract

PURPOSE:Oil temperature is controlled comparing with atmospheric temperature in such a way that thermal strain of machine tool produced by the temperature rise through circulating oil own, can be prevented. CONSTITUTION:When temperature difference is negative comparing with the setting value in the case of morning, a relay CR2 actuates and its contact point Cr2 closes so that electricity is charged to a heater 9 to heat oil and when designated temperature difference is obtained, the heating stops. When oil for oil hydraulic driving device works, its temperature rises suddenly so that temperature difference between oil and atmosphere is positive over setting value and a relay CR1 actuates. Then, closing its contact point Cr1, oil is cooled through the drive of a motor 8 of a cooler 7. Thus, oil temperature can be controlled always in comparison with atmospheric temperature. For this reason, machine remains constant thermally whole day for avoiding the variation of product accuracy.
