ABSTRACT:
A temperature control system for a machine tool capable of quickly responding to an ambient temperature change. A mechanical section of the machine tool is surrounded by a machine cover. Gas of which temperature is controlled by a temperature controller is discharged from bearing portions of gas bearings in the mechanical section to a region surrounded by the machine cover through a pipe and a gas bearing channel. A branch pipe is provided for directly introducing a part of gas discharged from the temperature controller to a temperature sensor inside the machine cover. The temperature sensor measures the temperature of gas mixture obtained by mixing the gas introduced directly from the pipe with air inside the machine cover in a predetermined ratio. The result of measurement by the temperature sensor is fed back to the temperature controller to control the temperature of the gas supplied to the gas bearings.
